+
+
+## 示例程序详细说明  
+
+本端侧图像分类Android示例程序分为JAVA层和JNI层，其中，JAVA层主要通过Android Camera 2 API实现摄像头获取图像帧，以及相应的图像处理等功能；JNI层在[Runtime](https://www.mindspore.cn/tutorial/zh-CN/master/use/lite_runtime.html)中完成模型推理的过程。
+
+> 此处详细说明示例程序的JNI层实现，JAVA层运用Android Camera 2 API实现开启设备摄像头以及图像帧处理等功能，需读者具备一定的Android开发基础知识。

+
+### 配置MindSpore Lite依赖项
+
+Android JNI层调用MindSpore C++ API时，需要相关库文件支持。可通过MindSpore Lite[源码编译](https://www.mindspore.cn/lite/docs/zh-CN/master/deploy.html)生成`libmindspore-lite.so`库文件，或直接下载MindSpore Lite提供的已编译完成的AMR64、ARM32、x86等[软件包](#TODO)。
+
+在Android Studio中将编译完成的`libmindspore-lite.so`库文件（可包含多个兼容架构），分别放置在APP工程的`app/libs/arm64-v8a`（ARM64）或`app/libs/armeabi-v7a`（ARM32）目录下，并在应用的`build.gradle`文件中配置CMake编译支持，以及`arm64-v8a`和`armeabi-v7a`的编译支持。
+
+本示例中，build过程由download.gradle文件自动从华为服务器下载libmindspore-lite.so以及OpenCV的libopencv_java4.so库文件，并放置在`app/libs/arm64-v8a`目录下。
+
+* 注：若自动下载失败，请手动下载相关库文件并将其放在对应位置：
+* libmindspore-lite.so [下载链接](https://download.mindspore.cn/model_zoo/official/lite/lib/mindspore%20version%200.7/libmindspore-lite.so)
+* libopencv_java4.so [下载链接](https://download.mindspore.cn/model_zoo/official/lite/lib/opencv%204.4.0/libopencv_java4.so)
+
+```
+android{
+    defaultConfig{
+        externalNativeBuild{
+            cmake{
+                arguments "-DANDROID_STL=c++_shared"
+            }
+        }
+
+        ndk{ 
+            abiFilters 'arm64-v8a'
+        }
+    }
+}
+```
+
+在`app/CMakeLists.txt`文件中建立`.so`库文件链接，如下所示。
+
+```
+# Set MindSpore Lite Dependencies.
+include_directories(${CMAKE_SOURCE_DIR}/src/main/cpp/include/MindSpore)
+add_library(mindspore-lite SHARED IMPORTED )
+set_target_properties(mindspore-lite PROPERTIES
+    IMPORTED_LOCATION "${CMAKE_SOURCE_DIR}/libs/libmindspore-lite.so")
+
+# Set OpenCV Dependecies.
+include_directories(${CMAKE_SOURCE_DIR}/opencv/sdk/native/jni/include)
+add_library(lib-opencv SHARED IMPORTED )
+set_target_properties(lib-opencv PROPERTIES
+    IMPORTED_LOCATION "${CMAKE_SOURCE_DIR}/libs/libopencv_java4.so")
+
+# Link target library.       
+target_link_libraries(
+    ...
+    mindspore-lite
+    lib-opencv
+    ...
+)
+```
+
+### 下载及部署模型文件
+
+从MindSpore Model Hub中下载模型文件，本示例程序中使用的终端图像分类模型文件为`mobilenetv2.ms`，同样通过download.gradle脚本在APP构建时自动下载，并放置在`app/src/main/assets`工程目录下。
+
+* 注：若下载失败请手动下载模型文件，mobilenetv2.ms [下载链接](https://download.mindspore.cn/model_zoo/official/lite/mobilenetv2_openimage_lite/mobilenetv2.ms)。
+
+
+### 编写端侧推理代码
+
+在JNI层调用MindSpore Lite C++ API实现端测推理。
+
+推理代码流程如下，完整代码请参见`src/cpp/MindSporeNetnative.cpp`。 
+
+1. 加载MindSpore Lite模型文件，构建上下文、会话以及用于推理的计算图。  
+
+    - 加载模型文件：创建并配置用于模型推理的上下文
+        ```cpp
+        // Buffer is the model data passed in by the Java layer
+        jlong bufferLen = env->GetDirectBufferCapacity(buffer);
+        char *modelBuffer = CreateLocalModelBuffer(env, buffer);  
+        ```
+        
+    - 创建会话
+        ```cpp
+        void **labelEnv = new void *;
+        MSNetWork *labelNet = new MSNetWork;
+        *labelEnv = labelNet;
+        
+        // Create context.
+        lite::Context *context = new lite::Context;
+        context->thread_num_ = numThread;  //Specify the number of threads to run inference
+        
+        // Create the mindspore session.
+        labelNet->CreateSessionMS(modelBuffer, bufferLen, context);
+        delete(context);
+        
+        ```
+        
+    - 加载模型文件并构建用于推理的计算图
+        ```cpp
+        void MSNetWork::CreateSessionMS(char* modelBuffer, size_t bufferLen, mindspore::lite::Context* ctx)
+        {
+            CreateSession(modelBuffer, bufferLen, ctx);  
+            session = mindspore::session::LiteSession::CreateSession(ctx);
+            auto model = mindspore::lite::Model::Import(modelBuffer, bufferLen);
+            int ret = session->CompileGraph(model); // Compile Graph 
+        }
+        ```
+    
+2. 将输入图片转换为传入MindSpore模型的Tensor格式。 
+
+    将待检测图片数据转换为输入MindSpore模型的Tensor。
+
+    ```cpp
+    // Convert the Bitmap image passed in from the JAVA layer to Mat for OpenCV processing
+    BitmapToMat(env, srcBitmap, matImageSrc);
+   // Processing such as zooming the picture size.
+    matImgPreprocessed = PreProcessImageData(matImageSrc);  
+
+    ImgDims inputDims; 
+    inputDims.channel = matImgPreprocessed.channels();
+    inputDims.width = matImgPreprocessed.cols;
+    inputDims.height = matImgPreprocessed.rows;
+    float *dataHWC = new float[inputDims.channel * inputDims.width * inputDims.height]
+
+    // Copy the image data to be detected to the dataHWC array.
+    // The dataHWC[image_size] array here is the intermediate variable of the input MindSpore model tensor.
+    float *ptrTmp = reinterpret_cast<float *>(matImgPreprocessed.data);
+    for(int i = 0; i < inputDims.channel * inputDims.width * inputDims.height; i++){
+       dataHWC[i] = ptrTmp[i];
+    }
+
+    // Assign dataHWC[image_size] to the input tensor variable.
+    auto msInputs = mSession->GetInputs();
+    auto inTensor = msInputs.front();
+    memcpy(inTensor->MutableData(), dataHWC,
+        inputDims.channel * inputDims.width * inputDims.height * sizeof(float));
+    delete[] (dataHWC);
+    ```
+    
+3. 对输入Tensor按照模型进行推理，获取输出Tensor，并进行后处理。    
+
+   - 图执行，端测推理。
+
+        ```cpp
+        // After the model and image tensor data is loaded, run inference.
+        auto status = mSession->RunGraph();
+        ```
+
+   - 获取输出数据。
+        ```cpp
+        // Get the mindspore inference results.
+        auto msOutputs = mSession->GetOutputMapByNode();
+        std::string retStr = ProcessRunnetResult(msOutputs);
+        ```
+        
+   - 输出数据的后续处理。
+        ```cpp
+        std::string ProcessRunnetResult(
+                std::unordered_map<std::string, std::vector<mindspore::tensor::MSTensor *>> msOutputs){
+        
+            // Get the branch of the model output.
+            // Use iterators to get map elements.
+            std::unordered_map<std::string, std::vector<mindspore::tensor::MSTensor *>>::iterator iter;
+            iter = msOutputs.begin();
+
+            // The mobilenetv2.ms model output just one branch.
+            auto outputString = iter->first;
+            auto outputTensor = iter->second;
+
+            float *temp_scores = static_cast<float * >(branch1_tensor[0]->MutableData());
+        
+            float scores[RET_CATEGORY_SUM];
+            for (int i = 0; i < RET_CATEGORY_SUM; ++i) {
+                if (temp_scores[i] > 0.5){
+                    MS_PRINT("MindSpore scores[%d] : [%f]",  i, temp_scores[i]);
+                }
+                scores[i] = temp_scores[i];
+            }
+   
+            // Converted to text information that needs to be displayed in the APP. 
+            std::string categoryScore = "";
+                for (int i = 0; i < RET_CATEGORY_SUM; ++i) {
+                    categoryScore += g_labels_name_map[i];
+                    categoryScore += ":";
+                    std::string score_str = std::to_string(scores[i]);
+                    categoryScore += score_str;
+                    categoryScore += ";";
+                }
+                return categoryScore;
+        }      
+        ```

+  @defgroup calib3d Camera Calibration and 3D Reconstruction
+
+The functions in this section use a so-called pinhole camera model. The view of a scene
+is obtained by projecting a scene's 3D point \f$P_w\f$ into the image plane using a perspective
+transformation which forms the corresponding pixel \f$p\f$. Both \f$P_w\f$ and \f$p\f$ are
+represented in homogeneous coordinates, i.e. as 3D and 2D homogeneous vector respectively. You will
+find a brief introduction to projective geometry, homogeneous vectors and homogeneous
+transformations at the end of this section's introduction. For more succinct notation, we often drop
+the 'homogeneous' and say vector instead of homogeneous vector.
+
+The distortion-free projective transformation given by a  pinhole camera model is shown below.
+
+\f[s \; p = A \begin{bmatrix} R|t \end{bmatrix} P_w,\f]
+
+where \f$P_w\f$ is a 3D point expressed with respect to the world coordinate system,
+\f$p\f$ is a 2D pixel in the image plane, \f$A\f$ is the intrinsic camera matrix,
+\f$R\f$ and \f$t\f$ are the rotation and translation that describe the change of coordinates from
+world to camera coordinate systems (or camera frame) and \f$s\f$ is the projective transformation's
+arbitrary scaling and not part of the camera model.
+
+The intrinsic camera matrix \f$A\f$ (notation used as in @cite Zhang2000 and also generally notated
+as \f$K\f$) projects 3D points given in the camera coordinate system to 2D pixel coordinates, i.e.
+
+\f[p = A P_c.\f]
+
+The camera matrix \f$A\f$ is composed of the focal lengths \f$f_x\f$ and \f$f_y\f$, which are
+expressed in pixel units, and the principal point \f$(c_x, c_y)\f$, that is usually close to the
+image center:
+
+\f[A = \vecthreethree{f_x}{0}{c_x}{0}{f_y}{c_y}{0}{0}{1},\f]
+
+and thus
+
+\f[s \vecthree{u}{v}{1} = \vecthreethree{f_x}{0}{c_x}{0}{f_y}{c_y}{0}{0}{1} \vecthree{X_c}{Y_c}{Z_c}.\f]
+
+The matrix of intrinsic parameters does not depend on the scene viewed. So, once estimated, it can
+be re-used as long as the focal length is fixed (in case of a zoom lens). Thus, if an image from the
+camera is scaled by a factor, all of these parameters need to be scaled (multiplied/divided,
+respectively) by the same factor.
+
+The joint rotation-translation matrix \f$[R|t]\f$ is the matrix product of a projective
+transformation and a homogeneous transformation. The 3-by-4 projective transformation maps 3D points
+represented in camera coordinates to 2D poins in the image plane and represented in normalized
+camera coordinates \f$x' = X_c / Z_c\f$ and \f$y' = Y_c / Z_c\f$:
+
+\f[Z_c \begin{bmatrix}
+x' \\
+y' \\
+1
+\end{bmatrix} = \begin{bmatrix}
+1 & 0 & 0 & 0 \\
+0 & 1 & 0 & 0 \\
+0 & 0 & 1 & 0
+\end{bmatrix}
+\begin{bmatrix}
+X_c \\
+Y_c \\
+Z_c \\
+1
+\end{bmatrix}.\f]
+
+The homogeneous transformation is encoded by the extrinsic parameters \f$R\f$ and \f$t\f$ and
+represents the change of basis from world coordinate system \f$w\f$ to the camera coordinate sytem
+\f$c\f$. Thus, given the representation of the point \f$P\f$ in world coordinates, \f$P_w\f$, we
+obtain \f$P\f$'s representation in the camera coordinate system, \f$P_c\f$, by
+
+\f[P_c = \begin{bmatrix}
+R & t \\
+0 & 1
+\end{bmatrix} P_w,\f]
+
+This homogeneous transformation is composed out of \f$R\f$, a 3-by-3 rotation matrix, and \f$t\f$, a
+3-by-1 translation vector:
+
+\f[\begin{bmatrix}
+R & t \\
+0 & 1
+\end{bmatrix} = \begin{bmatrix}
+r_{11} & r_{12} & r_{13} & t_x \\
+r_{21} & r_{22} & r_{23} & t_y \\
+r_{31} & r_{32} & r_{33} & t_z \\
+0 & 0 & 0 & 1
+\end{bmatrix},
+\f]
+
+and therefore
+
+\f[\begin{bmatrix}
+X_c \\
+Y_c \\
+Z_c \\
+1
+\end{bmatrix} = \begin{bmatrix}
+r_{11} & r_{12} & r_{13} & t_x \\
+r_{21} & r_{22} & r_{23} & t_y \\
+r_{31} & r_{32} & r_{33} & t_z \\
+0 & 0 & 0 & 1
+\end{bmatrix}
+\begin{bmatrix}
+X_w \\
+Y_w \\
+Z_w \\
+1
+\end{bmatrix}.\f]
+
+Combining the projective transformation and the homogeneous transformation, we obtain the projective
+transformation that maps 3D points in world coordinates into 2D points in the image plane and in
+normalized camera coordinates:
+
+\f[Z_c \begin{bmatrix}
+x' \\
+y' \\
+1
+\end{bmatrix} = \begin{bmatrix} R|t \end{bmatrix} \begin{bmatrix}
+X_w \\
+Y_w \\
+Z_w \\
+1
+\end{bmatrix} = \begin{bmatrix}
+r_{11} & r_{12} & r_{13} & t_x \\
+r_{21} & r_{22} & r_{23} & t_y \\
+r_{31} & r_{32} & r_{33} & t_z
+\end{bmatrix}
+\begin{bmatrix}
+X_w \\
+Y_w \\
+Z_w \\
+1
+\end{bmatrix},\f]
+
+with \f$x' = X_c / Z_c\f$ and \f$y' = Y_c / Z_c\f$. Putting the equations for instrincs and extrinsics together, we can write out
+\f$s \; p = A \begin{bmatrix} R|t \end{bmatrix} P_w\f$ as
+
+\f[s \vecthree{u}{v}{1} = \vecthreethree{f_x}{0}{c_x}{0}{f_y}{c_y}{0}{0}{1}
+\begin{bmatrix}
+r_{11} & r_{12} & r_{13} & t_x \\
+r_{21} & r_{22} & r_{23} & t_y \\
+r_{31} & r_{32} & r_{33} & t_z
+\end{bmatrix}
+\begin{bmatrix}
+X_w \\
+Y_w \\
+Z_w \\
+1
+\end{bmatrix}.\f]
+
+If \f$Z_c \ne 0\f$, the transformation above is equivalent to the following,
+
+\f[\begin{bmatrix}
+u \\
+v
+\end{bmatrix} = \begin{bmatrix}
+f_x X_c/Z_c + c_x \\
+f_y Y_c/Z_c + c_y
+\end{bmatrix}\f]
+
+with
+
+\f[\vecthree{X_c}{Y_c}{Z_c} = \begin{bmatrix}
+R|t
+\end{bmatrix} \begin{bmatrix}
+X_w \\
+Y_w \\
+Z_w \\
+1
+\end{bmatrix}.\f]
+
+The following figure illustrates the pinhole camera model.
+
+![Pinhole camera model](pics/pinhole_camera_model.png)
+
+Real lenses usually have some distortion, mostly radial distortion, and slight tangential distortion.
+So, the above model is extended as:
+
+\f[\begin{bmatrix}
+u \\
+v
+\end{bmatrix} = \begin{bmatrix}
+f_x x'' + c_x \\
+f_y y'' + c_y
+\end{bmatrix}\f]
+
+where
+
+\f[\begin{bmatrix}
+x'' \\
+y''
+\end{bmatrix} = \begin{bmatrix}
+x' \frac{1 + k_1 r^2 + k_2 r^4 + k_3 r^6}{1 + k_4 r^2 + k_5 r^4 + k_6 r^6} + 2 p_1 x' y' + p_2(r^2 + 2 x'^2) + s_1 r^2 + s_2 r^4 \\
+y' \frac{1 + k_1 r^2 + k_2 r^4 + k_3 r^6}{1 + k_4 r^2 + k_5 r^4 + k_6 r^6} + p_1 (r^2 + 2 y'^2) + 2 p_2 x' y' + s_3 r^2 + s_4 r^4 \\
+\end{bmatrix}\f]
+
+with
+
+\f[r^2 = x'^2 + y'^2\f]
+
+and
+
+\f[\begin{bmatrix}
+x'\\
+y'
+\end{bmatrix} = \begin{bmatrix}
+X_c/Z_c \\
+Y_c/Z_c
+\end{bmatrix},\f]
+
+if \f$Z_c \ne 0\f$.
+
+The distortion parameters are the radial coefficients \f$k_1\f$, \f$k_2\f$, \f$k_3\f$, \f$k_4\f$, \f$k_5\f$, and \f$k_6\f$
+,\f$p_1\f$ and \f$p_2\f$ are the tangential distortion coefficients, and \f$s_1\f$, \f$s_2\f$, \f$s_3\f$, and \f$s_4\f$,
+are the thin prism distortion coefficients. Higher-order coefficients are not considered in OpenCV.
+
+The next figures show two common types of radial distortion: barrel distortion
+(\f$ 1 + k_1 r^2 + k_2 r^4 + k_3 r^6 \f$ monotonically decreasing)
+and pincushion distortion (\f$ 1 + k_1 r^2 + k_2 r^4 + k_3 r^6 \f$ monotonically increasing).
+Radial distortion is always monotonic for real lenses,
+and if the estimator produces a non-monotonic result,
+this should be considered a calibration failure.
+More generally, radial distortion must be monotonic and the distortion function must be bijective.
+A failed estimation result may look deceptively good near the image center
+but will work poorly in e.g. AR/SFM applications.
+The optimization method used in OpenCV camera calibration does not include these constraints as
+the framework does not support the required integer programming and polynomial inequalities.
+See [issue #15992](https://github.com/opencv/opencv/issues/15992) for additional information.
+
+![](pics/distortion_examples.png)
+![](pics/distortion_examples2.png)
+
+In some cases, the image sensor may be tilted in order to focus an oblique plane in front of the
+camera (Scheimpflug principle). This can be useful for particle image velocimetry (PIV) or
+triangulation with a laser fan. The tilt causes a perspective distortion of \f$x''\f$ and
+\f$y''\f$. This distortion can be modeled in the following way, see e.g. @cite Louhichi07.
+
+\f[\begin{bmatrix}
+u \\
+v
+\end{bmatrix} = \begin{bmatrix}
+f_x x''' + c_x \\
+f_y y''' + c_y
+\end{bmatrix},\f]
+
+where
+
+\f[s\vecthree{x'''}{y'''}{1} =
+\vecthreethree{R_{33}(\tau_x, \tau_y)}{0}{-R_{13}(\tau_x, \tau_y)}
+{0}{R_{33}(\tau_x, \tau_y)}{-R_{23}(\tau_x, \tau_y)}
+{0}{0}{1} R(\tau_x, \tau_y) \vecthree{x''}{y''}{1}\f]
+
+and the matrix \f$R(\tau_x, \tau_y)\f$ is defined by two rotations with angular parameter
+\f$\tau_x\f$ and \f$\tau_y\f$, respectively,
+
+\f[
+R(\tau_x, \tau_y) =
+\vecthreethree{\cos(\tau_y)}{0}{-\sin(\tau_y)}{0}{1}{0}{\sin(\tau_y)}{0}{\cos(\tau_y)}
+\vecthreethree{1}{0}{0}{0}{\cos(\tau_x)}{\sin(\tau_x)}{0}{-\sin(\tau_x)}{\cos(\tau_x)} =
+\vecthreethree{\cos(\tau_y)}{\sin(\tau_y)\sin(\tau_x)}{-\sin(\tau_y)\cos(\tau_x)}
+{0}{\cos(\tau_x)}{\sin(\tau_x)}
+{\sin(\tau_y)}{-\cos(\tau_y)\sin(\tau_x)}{\cos(\tau_y)\cos(\tau_x)}.
+\f]
+
+In the functions below the coefficients are passed or returned as
+
+\f[(k_1, k_2, p_1, p_2[, k_3[, k_4, k_5, k_6 [, s_1, s_2, s_3, s_4[, \tau_x, \tau_y]]]])\f]
+
+vector. That is, if the vector contains four elements, it means that \f$k_3=0\f$ . The distortion
+coefficients do not depend on the scene viewed. Thus, they also belong to the intrinsic camera
+parameters. And they remain the same regardless of the captured image resolution. If, for example, a
+camera has been calibrated on images of 320 x 240 resolution, absolutely the same distortion
+coefficients can be used for 640 x 480 images from the same camera while \f$f_x\f$, \f$f_y\f$,
+\f$c_x\f$, and \f$c_y\f$ need to be scaled appropriately.
+
+The functions below use the above model to do the following:
+
+-   Project 3D points to the image plane given intrinsic and extrinsic parameters.
+-   Compute extrinsic parameters given intrinsic parameters, a few 3D points, and their
+projections.
+-   Estimate intrinsic and extrinsic camera parameters from several views of a known calibration
+pattern (every view is described by several 3D-2D point correspondences).
+-   Estimate the relative position and orientation of the stereo camera "heads" and compute the
+*rectification* transformation that makes the camera optical axes parallel.
+
+<B> Homogeneous Coordinates </B><br>
+Homogeneous Coordinates are a system of coordinates that are used in projective geometry. Their use
+allows to represent points at infinity by finite coordinates and simplifies formulas when compared
+to the cartesian counterparts, e.g. they have the advantage that affine transformations can be
+expressed as linear homogeneous transformation.
+
+One obtains the homogeneous vector \f$P_h\f$ by appending a 1 along an n-dimensional cartesian
+vector \f$P\f$ e.g. for a 3D cartesian vector the mapping \f$P \rightarrow P_h\f$ is:
+
+\f[\begin{bmatrix}
+X \\
+Y \\
+Z
+\end{bmatrix} \rightarrow \begin{bmatrix}
+X \\
+Y \\
+Z \\
+1
+\end{bmatrix}.\f]
+
+For the inverse mapping \f$P_h \rightarrow P\f$, one divides all elements of the homogeneous vector
+by its last element, e.g. for a 3D homogeneous vector one gets its 2D cartesian counterpart by:
+
+\f[\begin{bmatrix}
+X \\
+Y \\
+W
+\end{bmatrix} \rightarrow \begin{bmatrix}
+X / W \\
+Y / W
+\end{bmatrix},\f]
+
+if \f$W \ne 0\f$.
+
+Due to this mapping, all multiples \f$k P_h\f$, for \f$k \ne 0\f$, of a homogeneous point represent
+the same point \f$P_h\f$. An intuitive understanding of this property is that under a projective
+transformation, all multiples of \f$P_h\f$ are mapped to the same point. This is the physical
+observation one does for pinhole cameras, as all points along a ray through the camera's pinhole are
+projected to the same image point, e.g. all points along the red ray in the image of the pinhole
+camera model above would be mapped to the same image coordinate. This property is also the source
+for the scale ambiguity s in the equation of the pinhole camera model.
+
+As mentioned, by using homogeneous coordinates we can express any change of basis parameterized by
+\f$R\f$ and \f$t\f$ as a linear transformation, e.g. for the change of basis from coordinate system
+0 to coordinate system 1 becomes:
+
+\f[P_1 = R P_0 + t \rightarrow P_{h_1} = \begin{bmatrix}
+R & t \\
+0 & 1
+\end{bmatrix} P_{h_0}.\f]
+
+@note
+    -   Many functions in this module take a camera matrix as an input parameter. Although all
+        functions assume the same structure of this parameter, they may name it differently. The
+        parameter's description, however, will be clear in that a camera matrix with the structure
+        shown above is required.

+or vector\<Point2f\> .
+@param dstPoints Coordinates of the points in the target plane, a matrix of the type CV_32FC2 or
+a vector\<Point2f\> .
+@param method Method used to compute a homography matrix. The following methods are possible:
+-   **0** - a regular method using all the points, i.e., the least squares method
+-   **RANSAC** - RANSAC-based robust method
+-   **LMEDS** - Least-Median robust method
+-   **RHO** - PROSAC-based robust method
+@param ransacReprojThreshold Maximum allowed reprojection error to treat a point pair as an inlier
+(used in the RANSAC and RHO methods only). That is, if
+\f[\| \texttt{dstPoints} _i -  \texttt{convertPointsHomogeneous} ( \texttt{H} * \texttt{srcPoints} _i) \|_2  >  \texttt{ransacReprojThreshold}\f]
+then the point \f$i\f$ is considered as an outlier. If srcPoints and dstPoints are measured in pixels,
+it usually makes sense to set this parameter somewhere in the range of 1 to 10.
+@param mask Optional output mask set by a robust method ( RANSAC or LMEDS ). Note that the input
+mask values are ignored.
+@param maxIters The maximum number of RANSAC iterations.
+@param confidence Confidence level, between 0 and 1.
+
+The function finds and returns the perspective transformation \f$H\f$ between the source and the
+destination planes:
+
+\f[s_i  \vecthree{x'_i}{y'_i}{1} \sim H  \vecthree{x_i}{y_i}{1}\f]
+
+so that the back-projection error
+
+\f[\sum _i \left ( x'_i- \frac{h_{11} x_i + h_{12} y_i + h_{13}}{h_{31} x_i + h_{32} y_i + h_{33}} \right )^2+ \left ( y'_i- \frac{h_{21} x_i + h_{22} y_i + h_{23}}{h_{31} x_i + h_{32} y_i + h_{33}} \right )^2\f]
+
+is minimized. If the parameter method is set to the default value 0, the function uses all the point
+pairs to compute an initial homography estimate with a simple least-squares scheme.
+
+However, if not all of the point pairs ( \f$srcPoints_i\f$, \f$dstPoints_i\f$ ) fit the rigid perspective
+transformation (that is, there are some outliers), this initial estimate will be poor. In this case,
+you can use one of the three robust methods. The methods RANSAC, LMeDS and RHO try many different
+random subsets of the corresponding point pairs (of four pairs each, collinear pairs are discarded), estimate the homography matrix
+using this subset and a simple least-squares algorithm, and then compute the quality/goodness of the
+computed homography (which is the number of inliers for RANSAC or the least median re-projection error for
+LMeDS). The best subset is then used to produce the initial estimate of the homography matrix and
+the mask of inliers/outliers.
+
+Regardless of the method, robust or not, the computed homography matrix is refined further (using
+inliers only in case of a robust method) with the Levenberg-Marquardt method to reduce the
+re-projection error even more.
+
+The methods RANSAC and RHO can handle practically any ratio of outliers but need a threshold to
+distinguish inliers from outliers. The method LMeDS does not need any threshold but it works
+correctly only when there are more than 50% of inliers. Finally, if there are no outliers and the
+noise is rather small, use the default method (method=0).
+
+The function is used to find initial intrinsic and extrinsic matrices. Homography matrix is
+determined up to a scale. Thus, it is normalized so that \f$h_{33}=1\f$. Note that whenever an \f$H\f$ matrix
+cannot be estimated, an empty one will be returned.

+components of the jacobian are returned via different output parameters.
+@param aspectRatio Optional "fixed aspect ratio" parameter. If the parameter is not 0, the
+function assumes that the aspect ratio (\f$f_x / f_y\f$) is fixed and correspondingly adjusts the

+
+The function computes the 2D projections of 3D points to the image plane, given intrinsic and
+extrinsic camera parameters. Optionally, the function computes Jacobians -matrices of partial
+derivatives of image points coordinates (as functions of all the input parameters) with respect to
+the particular parameters, intrinsic and/or extrinsic. The Jacobians are used during the global
+optimization in @ref calibrateCamera, @ref solvePnP, and @ref stereoCalibrate. The function itself

+parameters.
+
+@note By setting rvec = tvec = \f$[0, 0, 0]\f$, or by setting cameraMatrix to a 3x3 identity matrix,
+or by passing zero distortion coefficients, one can get various useful partial cases of the
+function. This means, one can compute the distorted coordinates for a sparse set of points or apply
+a perspective transformation (and also compute the derivatives) in the ideal zero-distortion setup.

+/** @brief Finds an object pose from 3D-2D point correspondences.
+This function returns the rotation and the translation vectors that transform a 3D point expressed in the object
+coordinate frame to the camera coordinate frame, using different methods:
+- P3P methods (@ref SOLVEPNP_P3P, @ref SOLVEPNP_AP3P): need 4 input points to return a unique solution.
+- @ref SOLVEPNP_IPPE Input points must be >= 4 and object points must be coplanar.
+- @ref SOLVEPNP_IPPE_SQUARE Special case suitable for marker pose estimation.
+Number of input points must be 4. Object points must be defined in the following order:
+  - point 0: [-squareLength / 2,  squareLength / 2, 0]
+  - point 1: [ squareLength / 2,  squareLength / 2, 0]
+  - point 2: [ squareLength / 2, -squareLength / 2, 0]
+  - point 3: [-squareLength / 2, -squareLength / 2, 0]
+- for all the other flags, number of input points must be >= 4 and object points can be in any configuration.
+
+@param objectPoints Array of object points in the object coordinate space, Nx3 1-channel or
+1xN/Nx1 3-channel, where N is the number of points. vector\<Point3d\> can be also passed here.
+@param imagePoints Array of corresponding image points, Nx2 1-channel or 1xN/Nx1 2-channel,
+where N is the number of points. vector\<Point2d\> can be also passed here.
+@param cameraMatrix Input camera matrix \f$A = \vecthreethree{f_x}{0}{c_x}{0}{f_y}{c_y}{0}{0}{1}\f$ .
+@param distCoeffs Input vector of distortion coefficients
+\f$(k_1, k_2, p_1, p_2[, k_3[, k_4, k_5, k_6 [, s_1, s_2, s_3, s_4[, \tau_x, \tau_y]]]])\f$ of
+4, 5, 8, 12 or 14 elements. If the vector is NULL/empty, the zero distortion coefficients are
+assumed.
+@param rvec Output rotation vector (see @ref Rodrigues ) that, together with tvec, brings points from
+the model coordinate system to the camera coordinate system.
+@param tvec Output translation vector.
+@param useExtrinsicGuess Parameter used for #SOLVEPNP_ITERATIVE. If true (1), the function uses
+the provided rvec and tvec values as initial approximations of the rotation and translation
+vectors, respectively, and further optimizes them.
+@param flags Method for solving a PnP problem:
+-   **SOLVEPNP_ITERATIVE** Iterative method is based on a Levenberg-Marquardt optimization. In
+this case the function finds such a pose that minimizes reprojection error, that is the sum
+of squared distances between the observed projections imagePoints and the projected (using
+projectPoints ) objectPoints .
+-   **SOLVEPNP_P3P** Method is based on the paper of X.S. Gao, X.-R. Hou, J. Tang, H.-F. Chang
+"Complete Solution Classification for the Perspective-Three-Point Problem" (@cite gao2003complete).
+In this case the function requires exactly four object and image points.
+-   **SOLVEPNP_AP3P** Method is based on the paper of T. Ke, S. Roumeliotis
+"An Efficient Algebraic Solution to the Perspective-Three-Point Problem" (@cite Ke17).
+In this case the function requires exactly four object and image points.
+-   **SOLVEPNP_EPNP** Method has been introduced by F. Moreno-Noguer, V. Lepetit and P. Fua in the
+paper "EPnP: Efficient Perspective-n-Point Camera Pose Estimation" (@cite lepetit2009epnp).
+-   **SOLVEPNP_DLS** Method is based on the paper of J. Hesch and S. Roumeliotis.
+"A Direct Least-Squares (DLS) Method for PnP" (@cite hesch2011direct).
+-   **SOLVEPNP_UPNP** Method is based on the paper of A. Penate-Sanchez, J. Andrade-Cetto,
+F. Moreno-Noguer. "Exhaustive Linearization for Robust Camera Pose and Focal Length
+Estimation" (@cite penate2013exhaustive). In this case the function also estimates the parameters \f$f_x\f$ and \f$f_y\f$
+assuming that both have the same value. Then the cameraMatrix is updated with the estimated
+focal length.
+-   **SOLVEPNP_IPPE** Method is based on the paper of T. Collins and A. Bartoli.
+"Infinitesimal Plane-Based Pose Estimation" (@cite Collins14). This method requires coplanar object points.
+-   **SOLVEPNP_IPPE_SQUARE** Method is based on the paper of Toby Collins and Adrien Bartoli.
+"Infinitesimal Plane-Based Pose Estimation" (@cite Collins14). This method is suitable for marker pose estimation.
+It requires 4 coplanar object points defined in the following order:
+  - point 0: [-squareLength / 2,  squareLength / 2, 0]
+  - point 1: [ squareLength / 2,  squareLength / 2, 0]
+  - point 2: [ squareLength / 2, -squareLength / 2, 0]
+  - point 3: [-squareLength / 2, -squareLength / 2, 0]
+
+The function estimates the object pose given a set of object points, their corresponding image
+projections, as well as the camera matrix and the distortion coefficients, see the figure below
+(more precisely, the X-axis of the camera frame is pointing to the right, the Y-axis downward
+and the Z-axis forward).
+

+
+Points expressed in the world frame \f$ \bf{X}_w \f$ are projected into the image plane \f$ \left[ u, v \right] \f$
+using the perspective projection model \f$ \Pi \f$ and the camera intrinsic parameters matrix \f$ \bf{A} \f$:

+@note
+   -   An example of how to use solvePnP for planar augmented reality can be found at
+        opencv_source_code/samples/python/plane_ar.py
+   -   If you are using Python:
+        - Numpy array slices won't work as input because solvePnP requires contiguous
+        arrays (enforced by the assertion using cv::Mat::checkVector() around line 55 of
+        modules/calib3d/src/solvepnp.cpp version 2.4.9)
+        - The P3P algorithm requires image points to be in an array of shape (N,1,2) due
+        to its calling of cv::undistortPoints (around line 75 of modules/calib3d/src/solvepnp.cpp version 2.4.9)
+        which requires 2-channel information.
+        - Thus, given some data D = np.array(...) where D.shape = (N,M), in order to use a subset of
+        it as, e.g., imagePoints, one must effectively copy it into a new array: imagePoints =
+        np.ascontiguousarray(D[:,:2]).reshape((N,1,2))
+   -   The methods **SOLVEPNP_DLS** and **SOLVEPNP_UPNP** cannot be used as the current implementations are
+       unstable and sometimes give completely wrong results. If you pass one of these two
+       flags, **SOLVEPNP_EPNP** method will be used instead.
+   -   The minimum number of points is 4 in the general case. In the case of **SOLVEPNP_P3P** and **SOLVEPNP_AP3P**
+       methods, it is required to use exactly 4 points (the first 3 points are used to estimate all the solutions
+       of the P3P problem, the last one is used to retain the best solution that minimizes the reprojection error).
+   -   With **SOLVEPNP_ITERATIVE** method and `useExtrinsicGuess=true`, the minimum number of points is 3 (3 points
+       are sufficient to compute a pose but there are up to 4 solutions). The initial solution should be close to the
+       global solution to converge.
+   -   With **SOLVEPNP_IPPE** input points must be >= 4 and object points must be coplanar.
+   -   With **SOLVEPNP_IPPE_SQUARE** this is a special case suitable for marker pose estimation.
+       Number of input points must be 4. Object points must be defined in the following order:
+         - point 0: [-squareLength / 2,  squareLength / 2, 0]

+@note
+   -   An example of how to use solvePnP for planar augmented reality can be found at
+        opencv_source_code/samples/python/plane_ar.py
+   -   If you are using Python:
+        - Numpy array slices won't work as input because solvePnP requires contiguous
+        arrays (enforced by the assertion using cv::Mat::checkVector() around line 55 of
+        modules/calib3d/src/solvepnp.cpp version 2.4.9)
+        - The P3P algorithm requires image points to be in an array of shape (N,1,2) due
+        to its calling of cv::undistortPoints (around line 75 of modules/calib3d/src/solvepnp.cpp version 2.4.9)
+        which requires 2-channel information.
+        - Thus, given some data D = np.array(...) where D.shape = (N,M), in order to use a subset of
+        it as, e.g., imagePoints, one must effectively copy it into a new array: imagePoints =
+        np.ascontiguousarray(D[:,:2]).reshape((N,1,2))
+   -   The methods **SOLVEPNP_DLS** and **SOLVEPNP_UPNP** cannot be used as the current implementations are
+       unstable and sometimes give completely wrong results. If you pass one of these two
+       flags, **SOLVEPNP_EPNP** method will be used instead.
+   -   The minimum number of points is 4 in the general case. In the case of **SOLVEPNP_P3P** and **SOLVEPNP_AP3P**
+       methods, it is required to use exactly 4 points (the first 3 points are used to estimate all the solutions
+       of the P3P problem, the last one is used to retain the best solution that minimizes the reprojection error).
+   -   With **SOLVEPNP_ITERATIVE** method and `useExtrinsicGuess=true`, the minimum number of points is 3 (3 points
+       are sufficient to compute a pose but there are up to 4 solutions). The initial solution should be close to the
+       global solution to converge.
+   -   With **SOLVEPNP_IPPE** input points must be >= 4 and object points must be coplanar.
+   -   With **SOLVEPNP_IPPE_SQUARE** this is a special case suitable for marker pose estimation.
+       Number of input points must be 4. Object points must be defined in the following order:
+         - point 0: [-squareLength / 2,  squareLength / 2, 0]
+         - point 1: [ squareLength / 2,  squareLength / 2, 0]

+@cite duda2018 "Accurate Detection and Localization of Checkerboard Corners for
+Calibration" demonstrating that the returned sub-pixel positions are more
+accurate than the one returned by cornerSubPix allowing a precise camera
+calibration for demanding applications.
+
+In the case, the flags **CALIB_CB_LARGER** or **CALIB_CB_MARKER** are given,
+the result can be recovered from the optional meta array. Both flags are
+helpful to use calibration patterns exceeding the field of view of the camera.
+These oversized patterns allow more accurate calibrations as corners can be
+utilized, which are as close as possible to the image borders.  For a

+below) can be used to move the origin of the board to the location where the
+black circle is located.
+
+@note The function requires a white boarder with roughly the same width as one
+of the checkerboard fields around the whole board to improve the detection in
+various environments. In addition, because of the localized radon
+transformation it is beneficial to use round corners for the field corners
+which are located on the outside of the board. The following figure illustrates

+/** @brief Finds the camera intrinsic and extrinsic parameters from several views of a calibration
+pattern.
+
+@param objectPoints In the new interface it is a vector of vectors of calibration pattern points in
+the calibration pattern coordinate space (e.g. std::vector<std::vector<cv::Vec3f>>). The outer
+vector contains as many elements as the number of pattern views. If the same calibration pattern
+is shown in each view and it is fully visible, all the vectors will be the same. Although, it is
+possible to use partially occluded patterns or even different patterns in different views. Then,
+the vectors will be different. Although the points are 3D, they all lie in the calibration pattern's
+XY coordinate plane (thus 0 in the Z-coordinate), if the used calibration pattern is a planar rig.
+In the old interface all the vectors of object points from different views are concatenated
+together.
+@param imagePoints In the new interface it is a vector of vectors of the projections of calibration
+pattern points (e.g. std::vector<std::vector<cv::Vec2f>>). imagePoints.size() and
+objectPoints.size(), and imagePoints[i].size() and objectPoints[i].size() for each i, must be equal,
+respectively. In the old interface all the vectors of object points from different views are
+concatenated together.
+@param imageSize Size of the image used only to initialize the intrinsic camera matrix.
+@param cameraMatrix Input/output 3x3 floating-point camera matrix
+\f$A = \vecthreethree{f_x}{0}{c_x}{0}{f_y}{c_y}{0}{0}{1}\f$ . If CV\_CALIB\_USE\_INTRINSIC\_GUESS
+and/or CALIB_FIX_ASPECT_RATIO are specified, some or all of fx, fy, cx, cy must be
+initialized before calling the function.
+@param distCoeffs Input/output vector of distortion coefficients
+\f$(k_1, k_2, p_1, p_2[, k_3[, k_4, k_5, k_6 [, s_1, s_2, s_3, s_4[, \tau_x, \tau_y]]]])\f$ of
+4, 5, 8, 12 or 14 elements.
+@param rvecs Output vector of rotation vectors (@ref Rodrigues ) estimated for each pattern view
+(e.g. std::vector<cv::Mat>>). That is, each i-th rotation vector together with the corresponding
+i-th translation vector (see the next output parameter description) brings the calibration pattern
+from the object coordinate space (in which object points are specified) to the camera coordinate
+space. In more technical terms, the tuple of the i-th rotation and translation vector performs
+a change of basis from object coordinate space to camera coordinate space. Due to its duality, this
+tuple is equivalent to the position of the calibration pattern with respect to the camera coordinate
+space.
+@param tvecs Output vector of translation vectors estimated for each pattern view, see parameter
+describtion above.
+@param stdDeviationsIntrinsics Output vector of standard deviations estimated for intrinsic
+parameters. Order of deviations values:
+\f$(f_x, f_y, c_x, c_y, k_1, k_2, p_1, p_2, k_3, k_4, k_5, k_6 , s_1, s_2, s_3,
+ s_4, \tau_x, \tau_y)\f$ If one of parameters is not estimated, it's deviation is equals to zero.
+@param stdDeviationsExtrinsics Output vector of standard deviations estimated for extrinsic
+parameters. Order of deviations values: \f$(R_0, T_0, \dotsc , R_{M - 1}, T_{M - 1})\f$ where M is
+the number of pattern views. \f$R_i, T_i\f$ are concatenated 1x3 vectors.
+ @param perViewErrors Output vector of the RMS re-projection error estimated for each pattern view.
+@param flags Different flags that may be zero or a combination of the following values:
+-   **CALIB_USE_INTRINSIC_GUESS** cameraMatrix contains valid initial values of
+fx, fy, cx, cy that are optimized further. Otherwise, (cx, cy) is initially set to the image
+center ( imageSize is used), and focal distances are computed in a least-squares fashion.
+Note, that if intrinsic parameters are known, there is no need to use this function just to
+estimate extrinsic parameters. Use solvePnP instead.
+-   **CALIB_FIX_PRINCIPAL_POINT** The principal point is not changed during the global
+optimization. It stays at the center or at a different location specified when
+CALIB_USE_INTRINSIC_GUESS is set too.
+-   **CALIB_FIX_ASPECT_RATIO** The functions consider only fy as a free parameter. The
+ratio fx/fy stays the same as in the input cameraMatrix . When
+CALIB_USE_INTRINSIC_GUESS is not set, the actual input values of fx and fy are
+ignored, only their ratio is computed and used further.
+-   **CALIB_ZERO_TANGENT_DIST** Tangential distortion coefficients \f$(p_1, p_2)\f$ are set
+to zeros and stay zero.
+-   **CALIB_FIX_K1,...,CALIB_FIX_K6** The corresponding radial distortion
+coefficient is not changed during the optimization. If CALIB_USE_INTRINSIC_GUESS is
+set, the coefficient from the supplied distCoeffs matrix is used. Otherwise, it is set to 0.
+-   **CALIB_RATIONAL_MODEL** Coefficients k4, k5, and k6 are enabled. To provide the
+backward compatibility, this extra flag should be explicitly specified to make the
+calibration function use the rational model and return 8 coefficients. If the flag is not
+set, the function computes and returns only 5 distortion coefficients.
+-   **CALIB_THIN_PRISM_MODEL** Coefficients s1, s2, s3 and s4 are enabled. To provide the
+backward compatibility, this extra flag should be explicitly specified to make the
+calibration function use the thin prism model and return 12 coefficients. If the flag is not
+set, the function computes and returns only 5 distortion coefficients.
+-   **CALIB_FIX_S1_S2_S3_S4** The thin prism distortion coefficients are not changed during
+the optimization. If CALIB_USE_INTRINSIC_GUESS is set, the coefficient from the
+supplied distCoeffs matrix is used. Otherwise, it is set to 0.
+-   **CALIB_TILTED_MODEL** Coefficients tauX and tauY are enabled. To provide the
+backward compatibility, this extra flag should be explicitly specified to make the
+calibration function use the tilted sensor model and return 14 coefficients. If the flag is not
+set, the function computes and returns only 5 distortion coefficients.
+-   **CALIB_FIX_TAUX_TAUY** The coefficients of the tilted sensor model are not changed during
+the optimization. If CALIB_USE_INTRINSIC_GUESS is set, the coefficient from the
+supplied distCoeffs matrix is used. Otherwise, it is set to 0.
+@param criteria Termination criteria for the iterative optimization algorithm.
+
+@return the overall RMS re-projection error.
+
+The function estimates the intrinsic camera parameters and extrinsic parameters for each of the
+views. The algorithm is based on @cite Zhang2000 and @cite BouguetMCT . The coordinates of 3D object
+points and their corresponding 2D projections in each view must be specified. That may be achieved
+by using an object with known geometry and easily detectable feature points. Such an object is
+called a calibration rig or calibration pattern, and OpenCV has built-in support for a chessboard as
+a calibration rig (see @ref findChessboardCorners). Currently, initialization of intrinsic
+parameters (when CALIB_USE_INTRINSIC_GUESS is not set) is only implemented for planar calibration
+patterns (where Z-coordinates of the object points must be all zeros). 3D calibration rigs can also
+be used as long as initial cameraMatrix is provided.
+
+The algorithm performs the following steps:
+
+-   Compute the initial intrinsic parameters (the option only available for planar calibration
+    patterns) or read them from the input parameters. The distortion coefficients are all set to
+    zeros initially unless some of CALIB_FIX_K? are specified.
+
+-   Estimate the initial camera pose as if the intrinsic parameters have been already known. This is
+    done using solvePnP .
+
+-   Run the global Levenberg-Marquardt optimization algorithm to minimize the reprojection error,
+    that is, the total sum of squared distances between the observed feature points imagePoints and
+    the projected (using the current estimates for camera parameters and the poses) object points
+    objectPoints. See projectPoints for details.
+
+@note
+    If you use a non-square (i.e. non-N-by-N) grid and @ref findChessboardCorners for calibration,
+    and @ref calibrateCamera returns bad values (zero distortion coefficients, \f$c_x\f$ and
+    \f$c_y\f$ very far from the image center, and/or large differences between \f$f_x\f$ and
+    \f$f_y\f$ (ratios of 10:1 or more)), then you are probably using patternSize=cvSize(rows,cols)
+    instead of using patternSize=cvSize(cols,rows) in @ref findChessboardCorners.

+/** @brief Finds the camera intrinsic and extrinsic parameters from several views of a calibration pattern.
+
+This function is an extension of calibrateCamera() with the method of releasing object which was
+proposed in @cite strobl2011iccv. In many common cases with inaccurate, unmeasured, roughly planar
+targets (calibration plates), this method can dramatically improve the precision of the estimated
+camera parameters. Both the object-releasing method and standard method are supported by this
+function. Use the parameter **iFixedPoint** for method selection. In the internal implementation,
+calibrateCamera() is a wrapper for this function.
+
+@param objectPoints Vector of vectors of calibration pattern points in the calibration pattern
+coordinate space. See calibrateCamera() for details. If the method of releasing object to be used,
+the identical calibration board must be used in each view and it must be fully visible, and all
+objectPoints[i] must be the same and all points should be roughly close to a plane. **The calibration
+target has to be rigid, or at least static if the camera (rather than the calibration target) is
+shifted for grabbing images.**
+@param imagePoints Vector of vectors of the projections of calibration pattern points. See
+calibrateCamera() for details.
+@param imageSize Size of the image used only to initialize the intrinsic camera matrix.
+@param iFixedPoint The index of the 3D object point in objectPoints[0] to be fixed. It also acts as
+a switch for calibration method selection. If object-releasing method to be used, pass in the
+parameter in the range of [1, objectPoints[0].size()-2], otherwise a value out of this range will
+make standard calibration method selected. Usually the top-right corner point of the calibration
+board grid is recommended to be fixed when object-releasing method being utilized. According to
+\cite strobl2011iccv, two other points are also fixed. In this implementation, objectPoints[0].front
+and objectPoints[0].back.z are used. With object-releasing method, accurate rvecs, tvecs and
+newObjPoints are only possible if coordinates of these three fixed points are accurate enough.
+@param cameraMatrix Output 3x3 floating-point camera matrix. See calibrateCamera() for details.
+@param distCoeffs Output vector of distortion coefficients. See calibrateCamera() for details.
+@param rvecs Output vector of rotation vectors estimated for each pattern view. See calibrateCamera()
+for details.
+@param tvecs Output vector of translation vectors estimated for each pattern view.
+@param newObjPoints The updated output vector of calibration pattern points. The coordinates might
+be scaled based on three fixed points. The returned coordinates are accurate only if the above
+mentioned three fixed points are accurate. If not needed, noArray() can be passed in. This parameter
+is ignored with standard calibration method.
+@param stdDeviationsIntrinsics Output vector of standard deviations estimated for intrinsic parameters.
+See calibrateCamera() for details.
+@param stdDeviationsExtrinsics Output vector of standard deviations estimated for extrinsic parameters.
+See calibrateCamera() for details.
+@param stdDeviationsObjPoints Output vector of standard deviations estimated for refined coordinates
+of calibration pattern points. It has the same size and order as objectPoints[0] vector. This
+parameter is ignored with standard calibration method.
+ @param perViewErrors Output vector of the RMS re-projection error estimated for each pattern view.
+@param flags Different flags that may be zero or a combination of some predefined values. See
+calibrateCamera() for details. If the method of releasing object is used, the calibration time may
+be much longer. CALIB_USE_QR or CALIB_USE_LU could be used for faster calibration with potentially
+less precise and less stable in some rare cases.

+
+The function estimates the transformation between two cameras making a stereo pair. If one computes
+the poses of an object relative to the first camera and to the second camera,
+( \f$R_1\f$,\f$T_1\f$ ) and (\f$R_2\f$,\f$T_2\f$), respectively, for a stereo camera where the
+relative position and orientation between the two cameras are fixed, then those poses definitely
+relate to each other. This means, if the relative position and orientation (\f$R\f$,\f$T\f$) of the
+two cameras is known, it is possible to compute (\f$R_2\f$,\f$T_2\f$) when (\f$R_1\f$,\f$T_1\f$) is
+given. This is what the described function does. It computes (\f$R\f$,\f$T\f$) such that:
+
+\f[R_2=R R_1\f]
+\f[T_2=R T_1 + T.\f]
+
+Therefore, one can compute the coordinate representation of a 3D point for the second camera's
+coordinate system when given the point's coordinate representation in the first camera's coordinate
+system:
+
+\f[\begin{bmatrix}
+X_2 \\
+Y_2 \\
+Z_2 \\
+1
+\end{bmatrix} = \begin{bmatrix}
+R & T \\
+0 & 1
+\end{bmatrix} \begin{bmatrix}
+X_1 \\
+Y_1 \\
+Z_1 \\
+1
+\end{bmatrix}.\f]
+
+
+Optionally, it computes the essential matrix E:
+
+\f[E= \vecthreethree{0}{-T_2}{T_1}{T_2}{0}{-T_0}{-T_1}{T_0}{0} R\f]
+
+where \f$T_i\f$ are components of the translation vector \f$T\f$ : \f$T=[T_0, T_1, T_2]^T\f$ .
+And the function can also compute the fundamental matrix F:
+
+\f[F = cameraMatrix2^{-T}\cdot E \cdot cameraMatrix1^{-1}\f]
+
+Besides the stereo-related information, the function can also perform a full calibration of each of
+the two cameras. However, due to the high dimensionality of the parameter space and noise in the

+/** @brief Computes rectification transforms for each head of a calibrated stereo camera.
+
+@param cameraMatrix1 First camera matrix.
+@param distCoeffs1 First camera distortion parameters.
+@param cameraMatrix2 Second camera matrix.
+@param distCoeffs2 Second camera distortion parameters.
+@param imageSize Size of the image used for stereo calibration.
+@param R Rotation matrix from the coordinate system of the first camera to the second camera,
+see @ref stereoCalibrate.
+@param T Translation vector from the coordinate system of the first camera to the second camera,
+see @ref stereoCalibrate.
+@param R1 Output 3x3 rectification transform (rotation matrix) for the first camera. This matrix
+brings points given in the unrectified first camera's coordinate system to points in the rectified
+first camera's coordinate system. In more technical terms, it performs a change of basis from the
+unrectified first camera's coordinate system to the rectified first camera's coordinate system.
+@param R2 Output 3x3 rectification transform (rotation matrix) for the second camera. This matrix
+brings points given in the unrectified second camera's coordinate system to points in the rectified
+second camera's coordinate system. In more technical terms, it performs a change of basis from the
+unrectified second camera's coordinate system to the rectified second camera's coordinate system.
+@param P1 Output 3x4 projection matrix in the new (rectified) coordinate systems for the first
+camera, i.e. it projects points given in the rectified first camera coordinate system into the
+rectified first camera's image.
+@param P2 Output 3x4 projection matrix in the new (rectified) coordinate systems for the second
+camera, i.e. it projects points given in the rectified first camera coordinate system into the
+rectified second camera's image.
+@param Q Output \f$4 \times 4\f$ disparity-to-depth mapping matrix (see @ref reprojectImageTo3D).
+@param flags Operation flags that may be zero or CALIB_ZERO_DISPARITY . If the flag is set,
+the function makes the principal points of each camera have the same pixel coordinates in the
+rectified views. And if the flag is not set, the function may still shift the images in the
+horizontal or vertical direction (depending on the orientation of epipolar lines) to maximize the
+useful image area.
+@param alpha Free scaling parameter. If it is -1 or absent, the function performs the default
+scaling. Otherwise, the parameter should be between 0 and 1. alpha=0 means that the rectified
+images are zoomed and shifted so that only valid pixels are visible (no black areas after
+rectification). alpha=1 means that the rectified image is decimated and shifted so that all the
+pixels from the original images from the cameras are retained in the rectified images (no source
+image pixels are lost). Any intermediate value yields an intermediate result between
+those two extreme cases.
+@param newImageSize New image resolution after rectification. The same size should be passed to
+initUndistortRectifyMap (see the stereo_calib.cpp sample in OpenCV samples directory). When (0,0)
+is passed (default), it is set to the original imageSize . Setting it to a larger value can help you
+preserve details in the original image, especially when there is a big radial distortion.
+@param validPixROI1 Optional output rectangles inside the rectified images where all the pixels
+are valid. If alpha=0 , the ROIs cover the whole images. Otherwise, they are likely to be smaller
+(see the picture below).
+@param validPixROI2 Optional output rectangles inside the rectified images where all the pixels
+are valid. If alpha=0 , the ROIs cover the whole images. Otherwise, they are likely to be smaller
+(see the picture below).
+
+The function computes the rotation matrices for each camera that (virtually) make both camera image
+planes the same plane. Consequently, this makes all the epipolar lines parallel and thus simplifies
+the dense stereo correspondence problem. The function takes the matrices computed by stereoCalibrate
+as input. As output, it provides two rotation matrices and also two projection matrices in the new
+coordinates. The function distinguishes the following two cases:
+
+-   **Horizontal stereo**: the first and the second camera views are shifted relative to each other
+    mainly along the x-axis (with possible small vertical shift). In the rectified images, the
+    corresponding epipolar lines in the left and right cameras are horizontal and have the same
+    y-coordinate. P1 and P2 look like:
+
+    \f[\texttt{P1} = \begin{bmatrix}
+                        f & 0 & cx_1 & 0 \\
+                        0 & f & cy & 0 \\
+                        0 & 0 & 1 & 0
+                     \end{bmatrix}\f]
+
+    \f[\texttt{P2} = \begin{bmatrix}
+                        f & 0 & cx_2 & T_x*f \\
+                        0 & f & cy & 0 \\
+                        0 & 0 & 1 & 0
+                     \end{bmatrix} ,\f]
+
+    where \f$T_x\f$ is a horizontal shift between the cameras and \f$cx_1=cx_2\f$ if
+    CALIB_ZERO_DISPARITY is set.
+
+-   **Vertical stereo**: the first and the second camera views are shifted relative to each other
+    mainly in the vertical direction (and probably a bit in the horizontal direction too). The epipolar
+    lines in the rectified images are vertical and have the same x-coordinate. P1 and P2 look like:
+
+    \f[\texttt{P1} = \begin{bmatrix}
+                        f & 0 & cx & 0 \\
+                        0 & f & cy_1 & 0 \\
+                        0 & 0 & 1 & 0
+                     \end{bmatrix}\f]
+
+    \f[\texttt{P2} = \begin{bmatrix}
+                        f & 0 & cx & 0 \\
+                        0 & f & cy_2 & T_y*f \\
+                        0 & 0 & 1 & 0
+                     \end{bmatrix},\f]
+
+    where \f$T_y\f$ is a vertical shift between the cameras and \f$cy_1=cy_2\f$ if
+    CALIB_ZERO_DISPARITY is set.
+
+As you can see, the first three columns of P1 and P2 will effectively be the new "rectified" camera
+matrices. The matrices, together with R1 and R2 , can then be passed to initUndistortRectifyMap to
+initialize the rectification map for each camera.
+
+See below the screenshot from the stereo_calib.cpp sample. Some red horizontal lines pass through
+the corresponding image regions. This means that the images are well rectified, which is what most
+stereo correspondence algorithms rely on. The green rectangles are roi1 and roi2 . You see that
+their interiors are all valid pixels.

+  - F. Park, B. Martin Robot Sensor Calibration: Solving AX = XB on the Euclidean Group \cite Park94
+  - R. Horaud, F. Dornaika Hand-Eye Calibration \cite Horaud95
+

+
+The following picture describes the Hand-Eye calibration problem where the transformation between a camera ("eye")

+
+The calibration procedure is the following:
+  - a static calibration pattern is used to estimate the transformation between the target frame
+  and the camera frame
+  - the robot gripper is moved in order to acquire several poses
+  - for each pose, the homogeneous transformation between the gripper frame and the robot base frame is recorded using for

+A minimum of 2 motions with non parallel rotation axes are necessary to determine the hand-eye transformation.

+/** @brief Computes the undistortion and rectification transformation map.
+
+The function computes the joint undistortion and rectification transformation and represents the
+result in the form of maps for remap. The undistorted image looks like original, as if it is
+captured with a camera using the camera matrix =newCameraMatrix and zero distortion. In case of a
+monocular camera, newCameraMatrix is usually equal to cameraMatrix, or it can be computed by
+#getOptimalNewCameraMatrix for a better control over scaling. In case of a stereo camera,
+newCameraMatrix is normally set to P1 or P2 computed by #stereoRectify .
+
+Also, this new camera is oriented differently in the coordinate space, according to R. That, for
+example, helps to align two heads of a stereo camera so that the epipolar lines on both images
+become horizontal and have the same y- coordinate (in case of a horizontally aligned stereo camera).
+
+The function actually builds the maps for the inverse mapping algorithm that is used by remap. That
+is, for each pixel \f$(u, v)\f$ in the destination (corrected and rectified) image, the function
+computes the corresponding coordinates in the source image (that is, in the original image from
+camera). The following process is applied:
+\f[
+\begin{array}{l}
+x  \leftarrow (u - {c'}_x)/{f'}_x  \\
+y  \leftarrow (v - {c'}_y)/{f'}_y  \\

+
+In case of a stereo camera, this function is called twice: once for each camera head, after
+stereoRectify, which in its turn is called after #stereoCalibrate. But if the stereo camera
+was not calibrated, it is still possible to compute the rectification transformations directly from
+the fundamental matrix using #stereoRectifyUncalibrated. For each camera, the function computes
+homography H as the rectification transformation in a pixel domain, not a rotation matrix R in 3D

+to projectPoints. In case of a 3D object, it does not reconstruct its 3D coordinates, but for a
+planar object, it does, up to a translation vector, if the proper R is specified.
+
+For each observed point coordinate \f$(u, v)\f$ the function computes:

+    is passed (default), it is set to the original imageSize . Setting it to larger value can help you
+    preserve details in the original image, especially when there is a big radial distortion.
+    @param balance Sets the new focal length in range between the min focal length and the max focal
+    length. Balance is in range of [0, 1].
+    @param fov_scale Divisor for new focal length.

+This version of #norm calculates the absolute norm of src1. The type of norm to calculate is specified using #NormTypes.
+
+As example for one array consider the function \f$r(x)= \begin{pmatrix} x \\ 1-x \end{pmatrix}, x \in [-1;1]\f$.
+The \f$ L_{1}, L_{2} \f$ and \f$ L_{\infty} \f$ norm for the sample value \f$r(-1) = \begin{pmatrix} -1 \\ 2 \end{pmatrix}\f$
+is calculated as follows

+    \| r(-1) \|_{L_1} &= |-1| + |2| = 3 \\
+    \| r(-1) \|_{L_2} &= \sqrt{(-1)^{2} + (2)^{2}} = \sqrt{5} \\

+\f{align*}

+    \| r(0.5) \|_{L_2} &= \sqrt{(0.5)^{2} + (0.5)^{2}} = \sqrt{0.5} \\
+    \| r(0.5) \|_{L_\infty} &= \max(|0.5|,|0.5|) = 0.5.

+The following graphic shows all values for the three norm functions \f$\| r(x) \|_{L_1}, \| r(x) \|_{L_2}\f$ and \f$\| r(x) \|_{L_\infty}\f$.
+It is notable that the \f$ L_{1} \f$ norm forms the upper and the \f$ L_{\infty} \f$ norm forms the lower border for the example function \f$ r(x) \f$.

+
+The function cv::dft performs one of the following:
+-   Forward the Fourier transform of a 1D vector of N elements:
+    \f[Y = F^{(N)}  \cdot X,\f]
+    where \f$F^{(N)}_{jk}=\exp(-2\pi i j k/N)\f$ and \f$i=\sqrt{-1}\f$
+-   Inverse the Fourier transform of a 1D vector of N elements:
+    \f[\begin{array}{l} X'=  \left (F^{(N)} \right )^{-1}  \cdot Y =  \left (F^{(N)} \right )^*  \cdot y  \\ X = (1/N)  \cdot X, \end{array}\f]
+    where \f$F^*=\left(\textrm{Re}(F^{(N)})-\textrm{Im}(F^{(N)})\right)^T\f$
+-   Forward the 2D Fourier transform of a M x N matrix:
+    \f[Y = F^{(M)}  \cdot X  \cdot F^{(N)}\f]
+-   Inverse the 2D Fourier transform of a M x N matrix:
+    \f[\begin{array}{l} X'=  \left (F^{(M)} \right )^*  \cdot Y  \cdot \left (F^{(N)} \right )^* \\ X =  \frac{1}{M \cdot N} \cdot X' \end{array}\f]
+
+In case of real (single-channel) data, the output spectrum of the forward Fourier transform or input
+spectrum of the inverse Fourier transform can be represented in a packed format called *CCS*
+(complex-conjugate-symmetrical). It was borrowed from IPL (Intel\* Image Processing Library). Here
+is how 2D *CCS* spectrum looks:
+\f[\begin{bmatrix} Re Y_{0,0} & Re Y_{0,1} & Im Y_{0,1} & Re Y_{0,2} & Im Y_{0,2} &  \cdots & Re Y_{0,N/2-1} & Im Y_{0,N/2-1} & Re Y_{0,N/2}  \\ Re Y_{1,0} & Re Y_{1,1} & Im Y_{1,1} & Re Y_{1,2} & Im Y_{1,2} &  \cdots & Re Y_{1,N/2-1} & Im Y_{1,N/2-1} & Re Y_{1,N/2}  \\ Im Y_{1,0} & Re Y_{2,1} & Im Y_{2,1} & Re Y_{2,2} & Im Y_{2,2} &  \cdots & Re Y_{2,N/2-1} & Im Y_{2,N/2-1} & Im Y_{1,N/2}  \\ \hdotsfor{9} \\ Re Y_{M/2-1,0} &  Re Y_{M-3,1}  & Im Y_{M-3,1} &  \hdotsfor{3} & Re Y_{M-3,N/2-1} & Im Y_{M-3,N/2-1}& Re Y_{M/2-1,N/2}  \\ Im Y_{M/2-1,0} &  Re Y_{M-2,1}  & Im Y_{M-2,1} &  \hdotsfor{3} & Re Y_{M-2,N/2-1} & Im Y_{M-2,N/2-1}& Im Y_{M/2-1,N/2}  \\ Re Y_{M/2,0}  &  Re Y_{M-1,1} &  Im Y_{M-1,1} &  \hdotsfor{3} & Re Y_{M-1,N/2-1} & Im Y_{M-1,N/2-1}& Re Y_{M/2,N/2} \end{bmatrix}\f]
+
+In case of 1D transform of a real vector, the output looks like the first row of the matrix above.
+
+So, the function chooses an operation mode depending on the flags and size of the input array:
+-   If #DFT_ROWS is set or the input array has a single row or single column, the function
+    performs a 1D forward or inverse transform of each row of a matrix when #DFT_ROWS is set.
+    Otherwise, it performs a 2D transform.
+-   If the input array is real and #DFT_INVERSE is not set, the function performs a forward 1D or
+    2D transform:
+    -   When #DFT_COMPLEX_OUTPUT is set, the output is a complex matrix of the same size as
+        input.
+    -   When #DFT_COMPLEX_OUTPUT is not set, the output is a real matrix of the same size as
+        input. In case of 2D transform, it uses the packed format as shown above. In case of a
+        single 1D transform, it looks like the first row of the matrix above. In case of
+        multiple 1D transforms (when using the #DFT_ROWS flag), each row of the output matrix
+        looks like the first row of the matrix above.
+-   If the input array is complex and either #DFT_INVERSE or #DFT_REAL_OUTPUT are not set, the
+    output is a complex array of the same size as input. The function performs a forward or
+    inverse 1D or 2D transform of the whole input array or each row of the input array
+    independently, depending on the flags DFT_INVERSE and DFT_ROWS.
+-   When #DFT_INVERSE is set and the input array is real, or it is complex but #DFT_REAL_OUTPUT
+    is set, the output is a real array of the same size as input. The function performs a 1D or 2D
+    inverse transformation of the whole input array or each individual row, depending on the flags
+    #DFT_INVERSE and #DFT_ROWS.
+
+If #DFT_SCALE is set, the scaling is done after the transformation.
+
+Unlike dct , the function supports arrays of arbitrary size. But only those arrays are processed
+efficiently, whose sizes can be factorized in a product of small prime numbers (2, 3, and 5 in the
+current implementation). Such an efficient DFT size can be calculated using the getOptimalDFTSize
+method.
+
+The sample below illustrates how to calculate a DFT-based convolution of two 2D real arrays:
+@code
+    void convolveDFT(InputArray A, InputArray B, OutputArray C)
+    {
+        // reallocate the output array if needed
+        C.create(abs(A.rows - B.rows)+1, abs(A.cols - B.cols)+1, A.type());
+        Size dftSize;
+        // calculate the size of DFT transform
+        dftSize.width = getOptimalDFTSize(A.cols + B.cols - 1);
+        dftSize.height = getOptimalDFTSize(A.rows + B.rows - 1);
+
+        // allocate temporary buffers and initialize them with 0's
+        Mat tempA(dftSize, A.type(), Scalar::all(0));
+        Mat tempB(dftSize, B.type(), Scalar::all(0));
+
+        // copy A and B to the top-left corners of tempA and tempB, respectively
+        Mat roiA(tempA, Rect(0,0,A.cols,A.rows));
+        A.copyTo(roiA);
+        Mat roiB(tempB, Rect(0,0,B.cols,B.rows));
+        B.copyTo(roiB);
+
+        // now transform the padded A & B in-place;
+        // use "nonzeroRows" hint for faster processing
+        dft(tempA, tempA, 0, A.rows);
+        dft(tempB, tempB, 0, B.rows);
+
+        // multiply the spectrums;
+        // the function handles packed spectrum representations well
+        mulSpectrums(tempA, tempB, tempA);
+
+        // transform the product back from the frequency domain.
+        // Even though all the result rows will be non-zero,
+        // you need only the first C.rows of them, and thus you
+        // pass nonzeroRows == C.rows
+        dft(tempA, tempA, DFT_INVERSE + DFT_SCALE, C.rows);
+
+        // now copy the result back to C.
+        tempA(Rect(0, 0, C.cols, C.rows)).copyTo(C);
+
+        // all the temporary buffers will be deallocated automatically
+    }
+@endcode
+To optimize this sample, consider the following approaches:
+-   Since nonzeroRows != 0 is passed to the forward transform calls and since A and B are copied to
+    the top-left corners of tempA and tempB, respectively, it is not necessary to clear the whole
+    tempA and tempB. It is only necessary to clear the tempA.cols - A.cols ( tempB.cols - B.cols)
+    rightmost columns of the matrices.
+-   This DFT-based convolution does not have to be applied to the whole big arrays, especially if B
+    is significantly smaller than A or vice versa. Instead, you can calculate convolution by parts.
+    To do this, you need to split the output array C into multiple tiles. For each tile, estimate
+    which parts of A and B are required to calculate convolution in this tile. If the tiles in C are
+    too small, the speed will decrease a lot because of repeated work. In the ultimate case, when
+    each tile in C is a single pixel, the algorithm becomes equivalent to the naive convolution
+    algorithm. If the tiles are too big, the temporary arrays tempA and tempB become too big and
+    there is also a slowdown because of bad cache locality. So, there is an optimal tile size
+    somewhere in the middle.
+-   If different tiles in C can be calculated in parallel and, thus, the convolution is done by
+    parts, the loop can be threaded.
+
+All of the above improvements have been implemented in #matchTemplate and #filter2D . Therefore, by
+using them, you can get the performance even better than with the above theoretically optimal
+implementation. Though, those two functions actually calculate cross-correlation, not convolution,
+so you need to "flip" the second convolution operand B vertically and horizontally using flip .

+
+/** @brief Base storage class for GPU memory with reference counting.
+
+Its interface matches the Mat interface with the following limitations:
+
+-   no arbitrary dimensions support (only 2D)
+-   no functions that return references to their data (because references on GPU are not valid for
+    CPU)
+-   no expression templates technique support
+
+Beware that the latter limitation may lead to overloaded matrix operators that cause memory
+allocations. The GpuMat class is convertible to cuda::PtrStepSz and cuda::PtrStep so it can be
+passed directly to the kernel.
+
+@note In contrast with Mat, in most cases GpuMat::isContinuous() == false . This means that rows are
+aligned to a size depending on the hardware. Single-row GpuMat is always a continuous matrix.
+
+@note You are not recommended to leave static or global GpuMat variables allocated, that is, to rely
+on its destructor. The destruction order of such variables and CUDA context is undefined. GPU memory
+release function returns error if the CUDA context has been destroyed before.
+
+Some member functions are described as a "Blocking Call" while some are described as a
+"Non-Blocking Call". Blocking functions are synchronous to host. It is guaranteed that the GPU
+operation is finished when the function returns. However, non-blocking functions are asynchronous to
+host. Those functions may return even if the GPU operation is not finished.
+
+Compared to their blocking counterpart, non-blocking functions accept Stream as an additional
+argument. If a non-default stream is passed, the GPU operation may overlap with operations in other
+streams.

+/** @brief BufferPool for use with CUDA streams
+
+BufferPool utilizes Stream's allocator to create new buffers for GpuMat's. It is
+only useful when enabled with #setBufferPoolUsage.
+
+@code
+    setBufferPoolUsage(true);
+@endcode
+
+@note #setBufferPoolUsage must be called \em before any Stream declaration.
+
+Users may specify custom allocator for Stream and may implement their own stream based
+functions utilizing the same underlying GPU memory management.
+
+If custom allocator is not specified, BufferPool utilizes StackAllocator by
+default. StackAllocator allocates a chunk of GPU device memory beforehand,
+and when GpuMat is declared later on, it is given the pre-allocated memory.
+This kind of strategy reduces the number of calls for memory allocating APIs
+such as cudaMalloc or cudaMallocPitch.
+
+Below is an example that utilizes BufferPool with StackAllocator:
+
+@code
+    #include <opencv2/opencv.hpp>
+
+    using namespace cv;
+    using namespace cv::cuda
+
+    int main()
+    {
+        setBufferPoolUsage(true);                               // Tell OpenCV that we are going to utilize BufferPool
+        setBufferPoolConfig(getDevice(), 1024 * 1024 * 64, 2);  // Allocate 64 MB, 2 stacks (default is 10 MB, 5 stacks)
+
+        Stream stream1, stream2;                                // Each stream uses 1 stack
+        BufferPool pool1(stream1), pool2(stream2);
+
+        GpuMat d_src1 = pool1.getBuffer(4096, 4096, CV_8UC1);   // 16MB
+        GpuMat d_dst1 = pool1.getBuffer(4096, 4096, CV_8UC3);   // 48MB, pool1 is now full
+
+        GpuMat d_src2 = pool2.getBuffer(1024, 1024, CV_8UC1);   // 1MB
+        GpuMat d_dst2 = pool2.getBuffer(1024, 1024, CV_8UC3);   // 3MB
+
+        cvtColor(d_src1, d_dst1, CV_GRAY2BGR, 0, stream1);
+        cvtColor(d_src2, d_dst2, CV_GRAY2BGR, 0, stream2);
+    }
+@endcode
+
+If we allocate another GpuMat on pool1 in the above example, it will be carried out by
+the DefaultAllocator since the stack for pool1 is full.
+
+@code
+    GpuMat d_add1 = pool1.getBuffer(1024, 1024, CV_8UC1);   // Stack for pool1 is full, memory is allocated with DefaultAllocator
+@endcode
+
+If a third stream is declared in the above example, allocating with #getBuffer
+within that stream will also be carried out by the DefaultAllocator because we've run out of
+stacks.
+
+@code
+    Stream stream3;                                         // Only 2 stacks were allocated, we've run out of stacks
+    BufferPool pool3(stream3);
+    GpuMat d_src3 = pool3.getBuffer(1024, 1024, CV_8UC1);   // Memory is allocated with DefaultAllocator
+@endcode
+
+@warning When utilizing StackAllocator, deallocation order is important.
+
+Just like a stack, deallocation must be done in LIFO order. Below is an example of
+erroneous usage that violates LIFO rule. If OpenCV is compiled in Debug mode, this
+sample code will emit CV_Assert error.
+
+@code
+    int main()
+    {
+        setBufferPoolUsage(true);                               // Tell OpenCV that we are going to utilize BufferPool
+        Stream stream;                                          // A default size (10 MB) stack is allocated to this stream
+        BufferPool pool(stream);
+
+        GpuMat mat1 = pool.getBuffer(1024, 1024, CV_8UC1);      // Allocate mat1 (1MB)
+        GpuMat mat2 = pool.getBuffer(1024, 1024, CV_8UC1);      // Allocate mat2 (1MB)
+
+        mat1.release();                                         // erroneous usage : mat2 must be deallocated before mat1
+    }
+@endcode
+
+Since C++ local variables are destroyed in the reverse order of construction,
+the code sample below satisfies the LIFO rule. Local GpuMat's are deallocated
+and the corresponding memory is automatically returned to the pool for later usage.
+
+@code
+    int main()
+    {
+        setBufferPoolUsage(true);                               // Tell OpenCV that we are going to utilize BufferPool
+        setBufferPoolConfig(getDevice(), 1024 * 1024 * 64, 2);  // Allocate 64 MB, 2 stacks (default is 10 MB, 5 stacks)
+
+        Stream stream1, stream2;                                // Each stream uses 1 stack
+        BufferPool pool1(stream1), pool2(stream2);
+
+        for (int i = 0; i < 10; i++)
+        {
+            GpuMat d_src1 = pool1.getBuffer(4096, 4096, CV_8UC1);   // 16MB
+            GpuMat d_dst1 = pool1.getBuffer(4096, 4096, CV_8UC3);   // 48MB, pool1 is now full
+
+            GpuMat d_src2 = pool2.getBuffer(1024, 1024, CV_8UC1);   // 1MB
+            GpuMat d_dst2 = pool2.getBuffer(1024, 1024, CV_8UC3);   // 3MB
+
+            d_src1.setTo(Scalar(i), stream1);
+            d_src2.setTo(Scalar(i), stream2);
+
+            cvtColor(d_src1, d_dst1, CV_GRAY2BGR, 0, stream1);
+            cvtColor(d_src2, d_dst2, CV_GRAY2BGR, 0, stream2);
+                                                                    // The order of destruction of the local variables is:

+
+"Universal intrinsics" is a types and functions set intended to simplify vectorization of code on
+different platforms. Currently there are two supported SIMD extensions: __SSE/SSE2__ on x86
+architectures and __NEON__ on ARM architectures, both allow working with 128 bit registers
+containing packed values of different types. In case when there is no SIMD extension available
+during compilation, fallback C++ implementation of intrinsics will be chosen and code will work as
+expected although it could be slower.
+
+### Types
+
+There are several types representing 128-bit register as a vector of packed values, each type is
+implemented as a structure based on a one SIMD register.
+
+- cv::v_uint8x16 and cv::v_int8x16: sixteen 8-bit integer values (unsigned/signed) - char
+- cv::v_uint16x8 and cv::v_int16x8: eight 16-bit integer values (unsigned/signed) - short
+- cv::v_uint32x4 and cv::v_int32x4: four 32-bit integer values (unsigned/signed) - int
+- cv::v_uint64x2 and cv::v_int64x2: two 64-bit integer values (unsigned/signed) - int64
+- cv::v_float32x4: four 32-bit floating point values (signed) - float
+- cv::v_float64x2: two 64-bit floating point values (signed) - double
+
+@note
+cv::v_float64x2 is not implemented in NEON variant, if you want to use this type, don't forget to
+check the CV_SIMD128_64F preprocessor definition:
+@code
+#if CV_SIMD128_64F
+//...
+#endif
+@endcode
+
+### Load and store operations
+
+These operations allow to set contents of the register explicitly or by loading it from some memory
+block and to save contents of the register to memory block.
+
+- Constructors:
+@ref v_reg::v_reg(const _Tp *ptr) "from memory",
+@ref v_reg::v_reg(_Tp s0, _Tp s1) "from two values", ...
+- Other create methods:
+@ref v_setall_s8, @ref v_setall_u8, ...,

+//////////////////////// Input/Output Array Arguments /////////////////////////////////
+
+/** @brief This is the proxy class for passing read-only input arrays into OpenCV functions.
+
+It is defined as:
+@code
+    typedef const _InputArray& InputArray;
+@endcode
+where _InputArray is a class that can be constructed from `Mat`, `Mat_<T>`, `Matx<T, m, n>`,
+`std::vector<T>`, `std::vector<std::vector<T> >`, `std::vector<Mat>`, `std::vector<Mat_<T> >`,
+`UMat`, `std::vector<UMat>` or `double`. It can also be constructed from a matrix expression.
+
+Since this is mostly implementation-level class, and its interface may change in future versions, we
+do not describe it in details. There are a few key things, though, that should be kept in mind:
+
+-   When you see in the reference manual or in OpenCV source code a function that takes
+    InputArray, it means that you can actually pass `Mat`, `Matx`, `vector<T>` etc. (see above the
+    complete list).
+-   Optional input arguments: If some of the input arrays may be empty, pass cv::noArray() (or
+    simply cv::Mat() as you probably did before).
+-   The class is designed solely for passing parameters. That is, normally you *should not*
+    declare class members, local and global variables of this type.
+-   If you want to design your own function or a class method that can operate of arrays of
+    multiple types, you can use InputArray (or OutputArray) for the respective parameters. Inside
+    a function you should use _InputArray::getMat() method to construct a matrix header for the
+    array (without copying data). _InputArray::kind() can be used to distinguish Mat from
+    `vector<>` etc., but normally it is not needed.
+
+Here is how you can use a function that takes InputArray :
+@code
+    std::vector<Point2f> vec;
+    // points or a circle
+    for( int i = 0; i < 30; i++ )
+        vec.push_back(Point2f((float)(100 + 30*cos(i*CV_PI*2/5)),
+                              (float)(100 - 30*sin(i*CV_PI*2/5))));
+    cv::transform(vec, vec, cv::Matx23f(0.707, -0.707, 10, 0.707, 0.707, 20));
+@endcode
+That is, we form an STL vector containing points, and apply in-place affine transformation to the
+vector using the 2x3 matrix created inline as `Matx<float, 2, 3>` instance.
+
+Here is how such a function can be implemented (for simplicity, we implement a very specific case of
+it, according to the assertion statement inside) :
+@code
+    void myAffineTransform(InputArray _src, OutputArray _dst, InputArray _m)
+    {
+        // get Mat headers for input arrays. This is O(1) operation,
+        // unless _src and/or _m are matrix expressions.
+        Mat src = _src.getMat(), m = _m.getMat();
+        CV_Assert( src.type() == CV_32FC2 && m.type() == CV_32F && m.size() == Size(3, 2) );
+
+        // [re]create the output array so that it has the proper size and type.
+        // In case of Mat it calls Mat::create, in case of STL vector it calls vector::resize.
+        _dst.create(src.size(), src.type());
+        Mat dst = _dst.getMat();
+
+        for( int i = 0; i < src.rows; i++ )
+            for( int j = 0; j < src.cols; j++ )
+            {
+                Point2f pt = src.at<Point2f>(i, j);
+                dst.at<Point2f>(i, j) = Point2f(m.at<float>(0, 0)*pt.x +
+                                                m.at<float>(0, 1)*pt.y +
+                                                m.at<float>(0, 2),
+                                                m.at<float>(1, 0)*pt.x +
+                                                m.at<float>(1, 1)*pt.y +
+                                                m.at<float>(1, 2));
+            }
+    }
+@endcode
+There is another related type, InputArrayOfArrays, which is currently defined as a synonym for
+InputArray:
+@code
+    typedef InputArray InputArrayOfArrays;
+@endcode
+It denotes function arguments that are either vectors of vectors or vectors of matrices. A separate
+synonym is needed to generate Python/Java etc. wrappers properly. At the function implementation
+level their use is similar, but _InputArray::getMat(idx) should be used to get header for the
+idx-th component of the outer vector and _InputArray::size().area() should be used to find the
+number of components (vectors/matrices) of the outer vector.
+
+In general, type support is limited to cv::Mat types. Other types are forbidden.
+But in some cases we need to support passing of custom non-general Mat types, like arrays of cv::KeyPoint, cv::DMatch, etc.
+This data is not intended to be interpreted as an image data, or processed somehow like regular cv::Mat.
+To pass such custom type use rawIn() / rawOut() / rawInOut() wrappers.
+Custom type is wrapped as Mat-compatible `CV_8UC<N>` values (N = sizeof(T), N <= CV_CN_MAX).

+/** @brief This type is very similar to InputArray except that it is used for input/output and output function
+parameters.
+
+Just like with InputArray, OpenCV users should not care about OutputArray, they just pass `Mat`,
+`vector<T>` etc. to the functions. The same limitation as for `InputArray`: *Do not explicitly
+create OutputArray instances* applies here too.
+
+If you want to make your function polymorphic (i.e. accept different arrays as output parameters),
+it is also not very difficult. Take the sample above as the reference. Note that
+_OutputArray::create() needs to be called before _OutputArray::getMat(). This way you guarantee
+that the output array is properly allocated.
+
+Optional output parameters. If you do not need certain output array to be computed and returned to
+you, pass cv::noArray(), just like you would in the case of optional input array. At the
+implementation level, use _OutputArray::needed() to check if certain output array needs to be
+computed or not.
+
+There are several synonyms for OutputArray that are used to assist automatic Python/Java/... wrapper
+generators:
+@code
+    typedef OutputArray OutputArrayOfArrays;
+    typedef OutputArray InputOutputArray;
+    typedef OutputArray InputOutputArrayOfArrays;

+ /** @brief n-dimensional dense array class \anchor CVMat_Details
+
+The class Mat represents an n-dimensional dense numerical single-channel or multi-channel array. It
+can be used to store real or complex-valued vectors and matrices, grayscale or color images, voxel
+volumes, vector fields, point clouds, tensors, histograms (though, very high-dimensional histograms
+may be better stored in a SparseMat ). The data layout of the array `M` is defined by the array
+`M.step[]`, so that the address of element \f$(i_0,...,i_{M.dims-1})\f$, where \f$0\leq i_k<M.size[k]\f$, is
+computed as:
+\f[addr(M_{i_0,...,i_{M.dims-1}}) = M.data + M.step[0]*i_0 + M.step[1]*i_1 + ... + M.step[M.dims-1]*i_{M.dims-1}\f]
+In case of a 2-dimensional array, the above formula is reduced to:
+\f[addr(M_{i,j}) = M.data + M.step[0]*i + M.step[1]*j\f]
+Note that `M.step[i] >= M.step[i+1]` (in fact, `M.step[i] >= M.step[i+1]*M.size[i+1]` ). This means
+that 2-dimensional matrices are stored row-by-row, 3-dimensional matrices are stored plane-by-plane,
+and so on. M.step[M.dims-1] is minimal and always equal to the element size M.elemSize() .
+
+So, the data layout in Mat is compatible with the majority of dense array types from the standard
+toolkits and SDKs, such as Numpy (ndarray), Win32 (independent device bitmaps), and others,
+that is, with any array that uses *steps* (or *strides*) to compute the position of a pixel.
+Due to this compatibility, it is possible to make a Mat header for user-allocated data and process
+it in-place using OpenCV functions.
+
+There are many different ways to create a Mat object. The most popular options are listed below:
+
+- Use the create(nrows, ncols, type) method or the similar Mat(nrows, ncols, type[, fillValue])
+constructor. A new array of the specified size and type is allocated. type has the same meaning as
+in the cvCreateMat method. For example, CV_8UC1 means a 8-bit single-channel array, CV_32FC2
+means a 2-channel (complex) floating-point array, and so on.
+@code
+    // make a 7x7 complex matrix filled with 1+3j.
+    Mat M(7,7,CV_32FC2,Scalar(1,3));
+    // and now turn M to a 100x60 15-channel 8-bit matrix.
+    // The old content will be deallocated
+    M.create(100,60,CV_8UC(15));
+@endcode
+As noted in the introduction to this chapter, create() allocates only a new array when the shape
+or type of the current array are different from the specified ones.
+
+- Create a multi-dimensional array:
+@code
+    // create a 100x100x100 8-bit array
+    int sz[] = {100, 100, 100};
+    Mat bigCube(3, sz, CV_8U, Scalar::all(0));
+@endcode
+It passes the number of dimensions =1 to the Mat constructor but the created array will be
+2-dimensional with the number of columns set to 1. So, Mat::dims is always \>= 2 (can also be 0
+when the array is empty).
+
+- Use a copy constructor or assignment operator where there can be an array or expression on the
+right side (see below). As noted in the introduction, the array assignment is an O(1) operation
+because it only copies the header and increases the reference counter. The Mat::clone() method can
+be used to get a full (deep) copy of the array when you need it.
+
+- Construct a header for a part of another array. It can be a single row, single column, several
+rows, several columns, rectangular region in the array (called a *minor* in algebra) or a
+diagonal. Such operations are also O(1) because the new header references the same data. You can
+actually modify a part of the array using this feature, for example:
+@code
+    // add the 5-th row, multiplied by 3 to the 3rd row
+    M.row(3) = M.row(3) + M.row(5)*3;
+    // now copy the 7-th column to the 1-st column
+    // M.col(1) = M.col(7); // this will not work
+    Mat M1 = M.col(1);
+    M.col(7).copyTo(M1);
+    // create a new 320x240 image
+    Mat img(Size(320,240),CV_8UC3);
+    // select a ROI
+    Mat roi(img, Rect(10,10,100,100));
+    // fill the ROI with (0,255,0) (which is green in RGB space);
+    // the original 320x240 image will be modified
+    roi = Scalar(0,255,0);
+@endcode
+Due to the additional datastart and dataend members, it is possible to compute a relative
+sub-array position in the main *container* array using locateROI():
+@code
+    Mat A = Mat::eye(10, 10, CV_32S);
+    // extracts A columns, 1 (inclusive) to 3 (exclusive).
+    Mat B = A(Range::all(), Range(1, 3));
+    // extracts B rows, 5 (inclusive) to 9 (exclusive).
+    // that is, C \~ A(Range(5, 9), Range(1, 3))
+    Mat C = B(Range(5, 9), Range::all());
+    Size size; Point ofs;
+    C.locateROI(size, ofs);
+    // size will be (width=10,height=10) and the ofs will be (x=1, y=5)
+@endcode
+As in case of whole matrices, if you need a deep copy, use the `clone()` method of the extracted
+sub-matrices.
+
+- Make a header for user-allocated data. It can be useful to do the following:
+    -# Process "foreign" data using OpenCV (for example, when you implement a DirectShow\* filter or
+    a processing module for gstreamer, and so on). For example:
+    @code
+        void process_video_frame(const unsigned char* pixels,
+                                 int width, int height, int step)
+        {
+            Mat img(height, width, CV_8UC3, pixels, step);
+            GaussianBlur(img, img, Size(7,7), 1.5, 1.5);
+        }
+    @endcode
+    -# Quickly initialize small matrices and/or get a super-fast element access.
+    @code
+        double m[3][3] = {{a, b, c}, {d, e, f}, {g, h, i}};
+        Mat M = Mat(3, 3, CV_64F, m).inv();
+    @endcode
+    .
+
+- Use MATLAB-style array initializers, zeros(), ones(), eye(), for example:
+@code
+    // create a double-precision identity matrix and add it to M.
+    M += Mat::eye(M.rows, M.cols, CV_64F);
+@endcode
+
+- Use a comma-separated initializer:
+@code
+    // create a 3x3 double-precision identity matrix
+    Mat M = (Mat_<double>(3,3) << 1, 0, 0, 0, 1, 0, 0, 0, 1);
+@endcode
+With this approach, you first call a constructor of the Mat class with the proper parameters, and
+then you just put `<< operator` followed by comma-separated values that can be constants,
+variables, expressions, and so on. Also, note the extra parentheses required to avoid compilation
+errors.
+
+Once the array is created, it is automatically managed via a reference-counting mechanism. If the
+array header is built on top of user-allocated data, you should handle the data by yourself. The
+array data is deallocated when no one points to it. If you want to release the data pointed by a
+array header before the array destructor is called, use Mat::release().
+
+The next important thing to learn about the array class is element access. This manual already
+described how to compute an address of each array element. Normally, you are not required to use the
+formula directly in the code. If you know the array element type (which can be retrieved using the
+method Mat::type() ), you can access the element \f$M_{ij}\f$ of a 2-dimensional array as:
+@code
+    M.at<double>(i,j) += 1.f;
+@endcode
+assuming that `M` is a double-precision floating-point array. There are several variants of the method
+at for a different number of dimensions.
+
+If you need to process a whole row of a 2D array, the most efficient way is to get the pointer to
+the row first, and then just use the plain C operator [] :
+@code
+    // compute sum of positive matrix elements
+    // (assuming that M is a double-precision matrix)
+    double sum=0;
+    for(int i = 0; i < M.rows; i++)
+    {
+        const double* Mi = M.ptr<double>(i);
+        for(int j = 0; j < M.cols; j++)
+            sum += std::max(Mi[j], 0.);
+    }
+@endcode
+Some operations, like the one above, do not actually depend on the array shape. They just process
+elements of an array one by one (or elements from multiple arrays that have the same coordinates,
+for example, array addition). Such operations are called *element-wise*. It makes sense to check
+whether all the input/output arrays are continuous, namely, have no gaps at the end of each row. If
+yes, process them as a long single row:
+@code
+    // compute the sum of positive matrix elements, optimized variant
+    double sum=0;
+    int cols = M.cols, rows = M.rows;
+    if(M.isContinuous())
+    {
+        cols *= rows;
+        rows = 1;
+    }
+    for(int i = 0; i < rows; i++)
+    {
+        const double* Mi = M.ptr<double>(i);
+        for(int j = 0; j < cols; j++)
+            sum += std::max(Mi[j], 0.);
+    }
+@endcode
+In case of the continuous matrix, the outer loop body is executed just once. So, the overhead is
+smaller, which is especially noticeable in case of small matrices.
+
+Finally, there are STL-style iterators that are smart enough to skip gaps between successive rows:
+@code
+    // compute sum of positive matrix elements, iterator-based variant
+    double sum=0;
+    MatConstIterator_<double> it = M.begin<double>(), it_end = M.end<double>();
+    for(; it != it_end; ++it)
+        sum += std::max(*it, 0.);
+@endcode
+The matrix iterators are random-access iterators, so they can be passed to any STL algorithm,
+including std::sort().

+    can be required for filtering operations when pixels outside of the ROI should be taken into
+    account. When all the method parameters are positive, the ROI needs to grow in all directions by the

+
+    The method returns true if the matrix elements are stored continuously without gaps at the end of
+    each row. Otherwise, it returns false. Obviously, 1x1 or 1xN matrices are always continuous.
+    Matrices created with Mat::create are always continuous. But if you extract a part of the matrix
+    using Mat::col, Mat::diag, and so on, or constructed a matrix header for externally allocated data,
+    such matrices may no longer have this property.
+
+    The continuity flag is stored as a bit in the Mat::flags field and is computed automatically when
+    you construct a matrix header. Thus, the continuity check is a very fast operation, though
+    theoretically it could be done as follows:
+    @code
+        // alternative implementation of Mat::isContinuous()
+        bool myCheckMatContinuity(const Mat& m)
+        {
+            //return (m.flags & Mat::CONTINUOUS_FLAG) != 0;
+            return m.rows == 1 || m.step == m.cols*m.elemSize();
+        }
+    @endcode
+    The method is used in quite a few of OpenCV functions. The point is that element-wise operations
+    (such as arithmetic and logical operations, math functions, alpha blending, color space
+    transformations, and others) do not depend on the image geometry. Thus, if all the input and output
+    arrays are continuous, the functions can process them as very long single-row vectors. The example
+    below illustrates how an alpha-blending function can be implemented:
+    @code
+        template<typename T>
+        void alphaBlendRGBA(const Mat& src1, const Mat& src2, Mat& dst)
+        {
+            const float alpha_scale = (float)std::numeric_limits<T>::max(),
+                        inv_scale = 1.f/alpha_scale;

+                       src1.type() == CV_MAKETYPE(traits::Depth<T>::value, 4) &&
+                       src1.size() == src2.size());
+            Size size = src1.size();
+            dst.create(size, src1.type());
+
+            // here is the idiom: check the arrays for continuity and,
+            // if this is the case,
+            // treat the arrays as 1D vectors
+            if( src1.isContinuous() && src2.isContinuous() && dst.isContinuous() )
+            {
+                size.width *= size.height;
+                size.height = 1;
+            }
+            size.width *= 4;
+
+            for( int i = 0; i < size.height; i++ )
+            {
+                // when the arrays are continuous,
+                // the outer loop is executed only once
+                const T* ptr1 = src1.ptr<T>(i);
+                const T* ptr2 = src2.ptr<T>(i);
+                T* dptr = dst.ptr<T>(i);
+
+                for( int j = 0; j < size.width; j += 4 )
+                {
+                    float alpha = ptr1[j+3]*inv_scale, beta = ptr2[j+3]*inv_scale;
+                    dptr[j] = saturate_cast<T>(ptr1[j]*alpha + ptr2[j]*beta);
+                    dptr[j+1] = saturate_cast<T>(ptr1[j+1]*alpha + ptr2[j+1]*beta);
+                    dptr[j+2] = saturate_cast<T>(ptr1[j+2]*alpha + ptr2[j+2]*beta);
+                    dptr[j+3] = saturate_cast<T>((1 - (1-alpha)*(1-beta))*alpha_scale);

+    10-20 percents, especially if the image is rather small and the operation is quite simple.

+
+    The template methods return a reference to the specified array element. For the sake of higher
+    performance, the index range checks are only performed in the Debug configuration.
+
+    Note that the variants with a single index (i) can be used to access elements of single-row or
+    single-column 2-dimensional arrays. That is, if, for example, A is a 1 x N floating-point matrix and
+    B is an M x 1 integer matrix, you can simply write `A.at<float>(k+4)` and `B.at<int>(2*i+1)`
+    instead of `A.at<float>(0,k+4)` and `B.at<int>(2*i+1,0)`, respectively.
+
+    The example below initializes a Hilbert matrix:
+    @code
+        Mat H(100, 100, CV_64F);
+        for(int i = 0; i < H.rows; i++)
+            for(int j = 0; j < H.cols; j++)
+                H.at<double>(i,j)=1./(i+j+1);
+    @endcode
+
+    Keep in mind that the size identifier used in the at operator cannot be chosen at random. It depends
+    on the image from which you are trying to retrieve the data. The table below gives a better insight in this:
+     - If matrix is of type `CV_8U` then use `Mat.at<uchar>(y,x)`.
+     - If matrix is of type `CV_8S` then use `Mat.at<schar>(y,x)`.
+     - If matrix is of type `CV_16U` then use `Mat.at<ushort>(y,x)`.
+     - If matrix is of type `CV_16S` then use `Mat.at<short>(y,x)`.
+     - If matrix is of type `CV_32S`  then use `Mat.at<int>(y,x)`.
+     - If matrix is of type `CV_32F`  then use `Mat.at<float>(y,x)`.
+     - If matrix is of type `CV_64F` then use `Mat.at<double>(y,x)`.

+    template<typename _Tp> class Mat_ : public Mat
+    {
+    public:
+        // ... some specific methods
+        //         and
+        // no new extra fields
+    };
+@endcode
+The class `Mat_<_Tp>` is a *thin* template wrapper on top of the Mat class. It does not have any
+extra data fields. Nor this class nor Mat has any virtual methods. Thus, references or pointers to
+these two classes can be freely but carefully converted one to another. For example:
+@code{.cpp}
+    // create a 100x100 8-bit matrix
+    Mat M(100,100,CV_8U);
+    // this will be compiled fine. no any data conversion will be done.
+    Mat_<float>& M1 = (Mat_<float>&)M;
+    // the program is likely to crash at the statement below
+    M1(99,99) = 1.f;
+@endcode
+While Mat is sufficient in most cases, Mat_ can be more convenient if you use a lot of element
+access operations and if you know matrix type at the compilation time. Note that
+`Mat::at(int y,int x)` and `Mat_::operator()(int y,int x)` do absolutely the same
+and run at the same speed, but the latter is certainly shorter:
+@code{.cpp}
+    Mat_<double> M(20,20);
+    for(int i = 0; i < M.rows; i++)
+        for(int j = 0; j < M.cols; j++)
+            M(i,j) = 1./(i+j+1);
+    Mat E, V;
+    eigen(M,E,V);
+    cout << E.at<double>(0,0)/E.at<double>(M.rows-1,0);
+@endcode
+To use Mat_ for multi-channel images/matrices, pass Vec as a Mat_ parameter:
+@code{.cpp}
+    // allocate a 320x240 color image and fill it with green (in RGB space)
+    Mat_<Vec3b> img(240, 320, Vec3b(0,255,0));
+    // now draw a diagonal white line
+    for(int i = 0; i < 100; i++)
+        img(i,i)=Vec3b(255,255,255);
+    // and now scramble the 2nd (red) channel of each pixel
+    for(int i = 0; i < img.rows; i++)
+        for(int j = 0; j < img.cols; j++)
+            img(i,j)[2] ^= (uchar)(i ^ j);
+@endcode
+Mat_ is fully compatible with C++11 range-based for loop. For example such loop
+can be used to safely apply look-up table:
+@code{.cpp}
+void applyTable(Mat_<uchar>& I, const uchar* const table)
+{
+    for(auto& pixel : I)
+    {
+        pixel = table[pixel];
+    }
+}

+/////////////////////////// multi-dimensional sparse matrix //////////////////////////
+
+/** @brief The class SparseMat represents multi-dimensional sparse numerical arrays.
+
+Such a sparse array can store elements of any type that Mat can store. *Sparse* means that only
+non-zero elements are stored (though, as a result of operations on a sparse matrix, some of its
+stored elements can actually become 0. It is up to you to detect such elements and delete them
+using SparseMat::erase ). The non-zero elements are stored in a hash table that grows when it is
+filled so that the search time is O(1) in average (regardless of whether element is there or not).
+Elements can be accessed using the following methods:
+-   Query operations (SparseMat::ptr and the higher-level SparseMat::ref, SparseMat::value and
+    SparseMat::find), for example:
+    @code
+        const int dims = 5;
+        int size[5] = {10, 10, 10, 10, 10};
+        SparseMat sparse_mat(dims, size, CV_32F);
+        for(int i = 0; i < 1000; i++)
+        {
+            int idx[dims];
+            for(int k = 0; k < dims; k++)
+                idx[k] = rand() % size[k];
+            sparse_mat.ref<float>(idx) += 1.f;
+        }
+        cout << "nnz = " << sparse_mat.nzcount() << endl;
+    @endcode
+-   Sparse matrix iterators. They are similar to MatIterator but different from NAryMatIterator.
+    That is, the iteration loop is familiar to STL users:
+    @code
+        // prints elements of a sparse floating-point matrix
+        // and the sum of elements.
+        SparseMatConstIterator_<float>
+            it = sparse_mat.begin<float>(),
+            it_end = sparse_mat.end<float>();
+        double s = 0;
+        int dims = sparse_mat.dims();
+        for(; it != it_end; ++it)
+        {
+            // print element indices and the element value
+            const SparseMat::Node* n = it.node();
+            printf("(");
+            for(int i = 0; i < dims; i++)
+                printf("%d%s", n->idx[i], i < dims-1 ? ", " : ")");
+            printf(": %g\n", it.value<float>());
+            s += *it;
+        }
+        printf("Element sum is %g\n", s);
+    @endcode
+    If you run this loop, you will notice that elements are not enumerated in a logical order
+    (lexicographical, and so on). They come in the same order as they are stored in the hash table
+    (semi-randomly). You may collect pointers to the nodes and sort them to get the proper ordering.
+    Note, however, that pointers to the nodes may become invalid when you add more elements to the
+    matrix. This may happen due to possible buffer reallocation.
+-   Combination of the above 2 methods when you need to process 2 or more sparse matrices
+    simultaneously. For example, this is how you can compute unnormalized cross-correlation of the 2
+    floating-point sparse matrices:
+    @code
+        double cross_corr(const SparseMat& a, const SparseMat& b)
+        {
+            const SparseMat *_a = &a, *_b = &b;
+            // if b contains less elements than a,
+            // it is faster to iterate through b
+            if(_a->nzcount() > _b->nzcount())
+                std::swap(_a, _b);
+            SparseMatConstIterator_<float> it = _a->begin<float>(),
+                                           it_end = _a->end<float>();
+            double ccorr = 0;
+            for(; it != it_end; ++it)
+            {
+                // take the next element from the first matrix
+                float avalue = *it;
+                const Node* anode = it.node();
+                // and try to find an element with the same index in the second matrix.
+                // since the hash value depends only on the element index,
+                // reuse the hash value stored in the node
+                float bvalue = _b->value<float>(anode->idx,&anode->hashval);
+                ccorr += avalue*bvalue;
+            }
+            return ccorr;
+        }
+    @endcode

+/** @brief n-ary multi-dimensional array iterator.
+
+Use the class to implement unary, binary, and, generally, n-ary element-wise operations on
+multi-dimensional arrays. Some of the arguments of an n-ary function may be continuous arrays, some
+may be not. It is possible to use conventional MatIterator 's for each array but incrementing all of
+the iterators after each small operations may be a big overhead. In this case consider using
+NAryMatIterator to iterate through several matrices simultaneously as long as they have the same
+geometry (dimensionality and all the dimension sizes are the same). On each iteration `it.planes[0]`,
+`it.planes[1]`,... will be the slices of the corresponding matrices.
+
+The example below illustrates how you can compute a normalized and threshold 3D color histogram:
+@code

+        hist.create(3, histSize, CV_32F);
+
+        // and clear it
+        hist = Scalar(0);
+
+        // the loop below assumes that the image
+        // is a 8-bit 3-channel. check it.
+        CV_Assert(image.type() == CV_8UC3);

+        }

+/** @brief Matrix expression representation
+@anchor MatrixExpressions
+This is a list of implemented matrix operations that can be combined in arbitrary complex
+expressions (here A, B stand for matrices ( Mat ), s for a scalar ( Scalar ), alpha for a
+real-valued scalar ( double )):
+-   Addition, subtraction, negation: `A+B`, `A-B`, `A+s`, `A-s`, `s+A`, `s-A`, `-A`
+-   Scaling: `A*alpha`
+-   Per-element multiplication and division: `A.mul(B)`, `A/B`, `alpha/A`
+-   Matrix multiplication: `A*B`
+-   Transposition: `A.t()` (means A<sup>T</sup>)
+-   Matrix inversion and pseudo-inversion, solving linear systems and least-squares problems:
+    `A.inv([method]) (~ A<sup>-1</sup>)`,   `A.inv([method])*B (~ X: AX=B)`
+-   Comparison: `A cmpop B`, `A cmpop alpha`, `alpha cmpop A`, where *cmpop* is one of
+  `>`, `>=`, `==`, `!=`, `<=`, `<`. The result of comparison is an 8-bit single channel mask whose
+    elements are set to 255 (if the particular element or pair of elements satisfy the condition) or
+    0.
+-   Bitwise logical operations: `A logicop B`, `A logicop s`, `s logicop A`, `~A`, where *logicop* is one of
+  `&`, `|`, `^`.
+-   Element-wise minimum and maximum: `min(A, B)`, `min(A, alpha)`, `max(A, B)`, `max(A, alpha)`
+-   Element-wise absolute value: `abs(A)`
+-   Cross-product, dot-product: `A.cross(B)`, `A.dot(B)`
+-   Any function of matrix or matrices and scalars that returns a matrix or a scalar, such as norm,
+    mean, sum, countNonZero, trace, determinant, repeat, and others.
+-   Matrix initializers ( Mat::eye(), Mat::zeros(), Mat::ones() ), matrix comma-separated
+    initializers, matrix constructors and operators that extract sub-matrices (see Mat description).
+-   Mat_<destination_type>() constructors to cast the result to the proper type.
+@note Comma-separated initializers and probably some other operations may require additional
+explicit Mat() or Mat_<T>() constructor calls to resolve a possible ambiguity.
+
+Here are examples of matrix expressions:
+@code
+    // compute pseudo-inverse of A, equivalent to A.inv(DECOMP_SVD)
+    SVD svd(A);
+    Mat pinvA = svd.vt.t()*Mat::diag(1./svd.w)*svd.u.t();
+
+    // compute the new vector of parameters in the Levenberg-Marquardt algorithm
+    x -= (A.t()*A + lambda*Mat::eye(A.cols,A.cols,A.type())).inv(DECOMP_CHOLESKY)*(A.t()*err);
+
+    // sharpen image using "unsharp mask" algorithm
+    Mat blurred; double sigma = 1, threshold = 5, amount = 1;
+    GaussianBlur(img, blurred, Size(), sigma, sigma);
+    Mat lowContrastMask = abs(img - blurred) < threshold;
+    Mat sharpened = img*(1+amount) + blurred*(-amount);
+    img.copyTo(sharpened, lowContrastMask);
+@endcode

+/** @brief Template class for small matrices whose type and size are known at compilation time
+
+If you need a more flexible type, use Mat . The elements of the matrix M are accessible using the
+M(i,j) notation. Most of the common matrix operations (see also @ref MatrixExpressions ) are
+available. To do an operation on Matx that is not implemented, you can easily convert the matrix to
+Mat and backwards:
+@code{.cpp}
+    Matx33f m(1, 2, 3,
+              4, 5, 6,
+              7, 8, 9);
+    cout << sum(Mat(m*m.t())) << endl;
+@endcode
+Except of the plain constructor which takes a list of elements, Matx can be initialized from a C-array:
+@code{.cpp}
+    float values[] = { 1, 2, 3};
+    Matx31f m(values);
+@endcode
+In case if C++11 features are available, std::initializer_list can be also used to initialize Matx:
+@code{.cpp}
+    Matx31f m = { 1, 2, 3};
+@endcode

+
+/** @brief Template class for short numerical vectors, a partial case of Matx
+
+This template class represents short numerical vectors (of 1, 2, 3, 4 ... elements) on which you
+can perform basic arithmetical operations, access individual elements using [] operator etc. The
+vectors are allocated on stack, as opposite to std::valarray, std::vector, cv::Mat etc., which
+elements are dynamically allocated in the heap.
+
+The template takes 2 parameters:
+@tparam _Tp element type
+@tparam cn the number of elements
+
+In addition to the universal notation like Vec<float, 3>, you can use shorter aliases
+for the most popular specialized variants of Vec, e.g. Vec3f ~ Vec<float, 3>.
+
+It is possible to convert Vec\<T,2\> to/from Point_, Vec\<T,3\> to/from Point3_ , and Vec\<T,4\>
+to CvScalar or Scalar_. Use operator[] to access the elements of Vec.
+
+All the expected vector operations are also implemented:
+-   v1 = v2 + v3
+-   v1 = v2 - v3
+-   v1 = v2 \* scale
+-   v1 = scale \* v2
+-   v1 = -v2
+-   v1 += v2 and other augmenting operations
+-   v1 == v2, v1 != v2
+-   norm(v1) (euclidean norm)
+The Vec class is commonly used to describe pixel types of multi-channel arrays. See Mat for details.

+The implementation was done based on the beautifully clear explanatory article [An Introduction to
+the Conjugate Gradient Method Without the Agonizing
+Pain](http://www.cs.cmu.edu/~quake-papers/painless-conjugate-gradient.pdf) by Jonathan Richard
+Shewchuk. The method can be seen as an adaptation of a standard Conjugate Gradient method (see, for
+example <http://en.wikipedia.org/wiki/Conjugate_gradient_method>) for numerically solving the
+systems of linear equations.
+
+It should be noted, that this method, although deterministic, is rather a heuristic method and
+therefore may converge to a local minima, not necessary a global one. What is even more disastrous,
+most of its behaviour is ruled by gradient, therefore it essentially cannot distinguish between
+local minima and maxima. Therefore, if it starts sufficiently near to the local maximum, it may
+converge to it. Another obvious restriction is that it should be possible to compute the gradient of
+a function at any point, thus it is preferable to have analytic expression for gradient and
+computational burden should be born by the user.
+
+The latter responsibility is accomplished via the getGradient method of a
+MinProblemSolver::Function interface (which represents function being optimized). This method takes
+point a point in *n*-dimensional space (first argument represents the array of coordinates of that
+point) and compute its gradient (it should be stored in the second argument as an array).

+Several functions that are described below take CvFileStorage\* as inputs and allow the user to

+(such as matrices, sequences, graphs), and user-defined objects.
+
+OpenCV can read and write data in XML (<http://www.w3c.org/XML>), YAML (<http://www.yaml.org>) or
+JSON (<http://www.json.org/>) formats. Below is an example of 3x3 floating-point identity matrix A,
+stored in XML and YAML files
+using CXCore functions:
+XML:
+@code{.xml}
+    <?xml version="1.0">
+    <opencv_storage>
+    <A type_id="opencv-matrix">
+      <rows>3</rows>
+      <cols>3</cols>
+      <dt>f</dt>
+      <data>1. 0. 0. 0. 1. 0. 0. 0. 1.</data>
+    </A>
+    </opencv_storage>
+@endcode
+YAML:
+@code{.yaml}
+    %YAML:1.0

+      dt: f
+      data: [ 1., 0., 0., 0., 1., 0., 0., 0., 1.]
+@endcode
+As it can be seen from the examples, XML uses nested tags to represent hierarchy, while YAML uses
+indentation for that purpose (similar to the Python programming language).
+
+The same functions can read and write data in both formats; the particular format is determined by
+the extension of the opened file, ".xml" for XML files, ".yml" or ".yaml" for YAML and ".json" for
+JSON.

+XML/YAML/JSON file storages.     {#xml_storage}
+=======================
+Writing to a file storage.
+--------------------------
+You can store and then restore various OpenCV data structures to/from XML (<http://www.w3c.org/XML>),
+YAML (<http://www.yaml.org>) or JSON (<http://www.json.org/>) formats. Also, it is possible to store
+and load arbitrarily complex data structures, which include OpenCV data structures, as well as
+primitive data types (integer and floating-point numbers and text strings) as their elements.
+
+Use the following procedure to write something to XML, YAML or JSON:
+-# Create new FileStorage and open it for writing. It can be done with a single call to
+FileStorage::FileStorage constructor that takes a filename, or you can use the default constructor
+and then call FileStorage::open. Format of the file (XML, YAML or JSON) is determined from the filename
+extension (".xml", ".yml"/".yaml" and ".json", respectively)
+-# Write all the data you want using the streaming operator `<<`, just like in the case of STL
+streams.
+-# Close the file using FileStorage::release. FileStorage destructor also closes the file.
+
+Here is an example:
+@code
+    #include "opencv2/core.hpp"
+    #include <time.h>
+
+    using namespace cv;
+
+    int main(int, char** argv)
+    {
+        FileStorage fs("test.yml", FileStorage::WRITE);
+
+        fs << "frameCount" << 5;
+        time_t rawtime; time(&rawtime);
+        fs << "calibrationDate" << asctime(localtime(&rawtime));
+        Mat cameraMatrix = (Mat_<double>(3,3) << 1000, 0, 320, 0, 1000, 240, 0, 0, 1);
+        Mat distCoeffs = (Mat_<double>(5,1) << 0.1, 0.01, -0.001, 0, 0);
+        fs << "cameraMatrix" << cameraMatrix << "distCoeffs" << distCoeffs;
+        fs << "features" << "[";
+        for( int i = 0; i < 3; i++ )
+        {
+            int x = rand() % 640;
+            int y = rand() % 480;
+            uchar lbp = rand() % 256;
+
+            fs << "{:" << "x" << x << "y" << y << "lbp" << "[:";
+            for( int j = 0; j < 8; j++ )
+                fs << ((lbp >> j) & 1);
+            fs << "]" << "}";
+        }
+        fs << "]";
+        fs.release();
+        return 0;
+    }
+@endcode
+The sample above stores to YML an integer, a text string (calibration date), 2 matrices, and a custom
+structure "feature", which includes feature coordinates and LBP (local binary pattern) value. Here
+is output of the sample:
+@code{.yaml}
+%YAML:1.0
+frameCount: 5
+calibrationDate: "Fri Jun 17 14:09:29 2011\n"
+cameraMatrix: !!opencv-matrix
+   rows: 3
+   cols: 3
+   dt: d
+   data: [ 1000., 0., 320., 0., 1000., 240., 0., 0., 1. ]
+distCoeffs: !!opencv-matrix
+   rows: 5
+   cols: 1
+   dt: d
+   data: [ 1.0000000000000001e-01, 1.0000000000000000e-02,
+       -1.0000000000000000e-03, 0., 0. ]
+features:
+   - { x:167, y:49, lbp:[ 1, 0, 0, 1, 1, 0, 1, 1 ] }
+   - { x:298, y:130, lbp:[ 0, 0, 0, 1, 0, 0, 1, 1 ] }
+   - { x:344, y:158, lbp:[ 1, 1, 0, 0, 0, 0, 1, 0 ] }
+@endcode
+
+As an exercise, you can replace ".yml" with ".xml" or ".json" in the sample above and see, how the
+corresponding XML file will look like.
+
+Several things can be noted by looking at the sample code and the output:
+
+-   The produced YAML (and XML/JSON) consists of heterogeneous collections that can be nested. There are
+    2 types of collections: named collections (mappings) and unnamed collections (sequences). In mappings
+    each element has a name and is accessed by name. This is similar to structures and std::map in
+    C/C++ and dictionaries in Python. In sequences elements do not have names, they are accessed by
+    indices. This is similar to arrays and std::vector in C/C++ and lists, tuples in Python.
+    "Heterogeneous" means that elements of each single collection can have different types.
+
+    Top-level collection in YAML/XML/JSON is a mapping. Each matrix is stored as a mapping, and the matrix
+    elements are stored as a sequence. Then, there is a sequence of features, where each feature is
+    represented a mapping, and lbp value in a nested sequence.
+
+-   When you write to a mapping (a structure), you write element name followed by its value. When you
+    write to a sequence, you simply write the elements one by one. OpenCV data structures (such as
+    cv::Mat) are written in absolutely the same way as simple C data structures - using `<<`
+    operator.
+
+-   To write a mapping, you first write the special string `{` to the storage, then write the
+    elements as pairs (`fs << <element_name> << <element_value>`) and then write the closing
+    `}`.
+
+-   To write a sequence, you first write the special string `[`, then write the elements, then
+    write the closing `]`.
+
+-   In YAML/JSON (but not XML), mappings and sequences can be written in a compact Python-like inline
+    form. In the sample above matrix elements, as well as each feature, including its lbp value, is
+    stored in such inline form. To store a mapping/sequence in a compact form, put `:` after the
+    opening character, e.g. use `{:` instead of `{` and `[:` instead of `[`. When the
+    data is written to XML, those extra `:` are ignored.
+
+Reading data from a file storage.
+---------------------------------
+To read the previously written XML, YAML or JSON file, do the following:
+-#  Open the file storage using FileStorage::FileStorage constructor or FileStorage::open method.
+    In the current implementation the whole file is parsed and the whole representation of file
+    storage is built in memory as a hierarchy of file nodes (see FileNode)
+
+-#  Read the data you are interested in. Use FileStorage::operator [], FileNode::operator []
+    and/or FileNodeIterator.
+
+-#  Close the storage using FileStorage::release.
+
+Here is how to read the file created by the code sample above:
+@code
+    FileStorage fs2("test.yml", FileStorage::READ);
+
+    // first method: use (type) operator on FileNode.
+    int frameCount = (int)fs2["frameCount"];
+
+    String date;
+    // second method: use FileNode::operator >>
+    fs2["calibrationDate"] >> date;
+
+    Mat cameraMatrix2, distCoeffs2;
+    fs2["cameraMatrix"] >> cameraMatrix2;
+    fs2["distCoeffs"] >> distCoeffs2;
+
+    cout << "frameCount: " << frameCount << endl
+         << "calibration date: " << date << endl
+         << "camera matrix: " << cameraMatrix2 << endl
+         << "distortion coeffs: " << distCoeffs2 << endl;
+
+    FileNode features = fs2["features"];
+    FileNodeIterator it = features.begin(), it_end = features.end();
+    int idx = 0;
+    std::vector<uchar> lbpval;
+
+    // iterate through a sequence using FileNodeIterator
+    for( ; it != it_end; ++it, idx++ )
+    {
+        cout << "feature #" << idx << ": ";
+        cout << "x=" << (int)(*it)["x"] << ", y=" << (int)(*it)["y"] << ", lbp: (";
+        // you can also easily read numerical arrays using FileNode >> std::vector operator.
+        (*it)["lbp"] >> lbpval;
+        for( int i = 0; i < (int)lbpval.size(); i++ )
+            cout << " " << (int)lbpval[i];
+        cout << ")" << endl;
+    }
+    fs2.release();
+@endcode
+
+Format specification    {#format_spec}
+--------------------
+`([count]{u|c|w|s|i|f|d})`... where the characters correspond to fundamental C++ types:
+-   `u` 8-bit unsigned number
+-   `c` 8-bit signed number
+-   `w` 16-bit unsigned number
+-   `s` 16-bit signed number
+-   `i` 32-bit signed number
+-   `f` single precision floating-point number
+-   `d` double precision floating-point number
+-   `r` pointer, 32 lower bits of which are written as a signed integer. The type can be used to
+    store structures with links between the elements.
+
+`count` is the optional counter of values of a given type. For example, `2if` means that each array
+element is a structure of 2 integers, followed by a single-precision floating-point number. The
+equivalent notations of the above specification are `iif`, `2i1f` and so forth. Other examples: `u`
+means that the array consists of bytes, and `2d` means the array consists of pairs of doubles.

+
+/** @brief Template function for accurate conversion from one primitive type to another.
+
+ The function saturate_cast resembles the standard C++ cast operations, such as static_cast\<T\>()
+ and others. It perform an efficient and accurate conversion from one primitive type to another
+ (see the introduction chapter). saturate in the name means that when the input value v is out of the
+ range of the target type, the result is not formed just by taking low bits of the input, but instead
+ the value is clipped. For example:
+ @code
+ uchar a = saturate_cast<uchar>(-100); // a = 0 (UCHAR_MIN)
+ short b = saturate_cast<short>(33333.33333); // b = 32767 (SHRT_MAX)
+ @endcode
+ Such clipping is done when the target type is unsigned char , signed char , unsigned short or
+ signed short . For 32-bit integers, no clipping is done.
+
+ When the parameter is a floating-point value and the target type is an integer (8-, 16- or 32-bit),
+ the floating-point value is first rounded to the nearest integer and then clipped if needed (when
+ the target type is 8- or 16-bit).
+
+ @param v Function parameter.

+Helper header to support SIMD intrinsics (universal intrinsics) in user code.
+Intrinsics documentation: https://docs.opencv.org/master/df/d91/group__core__hal__intrin.html
+
+
+Checks of target CPU instruction set based on compiler definitions don't work well enough.
+More reliable solutions require utilization of configuration systems (like CMake).
+
+So, probably you need to specify your own configuration.
+
+You can do that via CMake in this way:
+    add_definitions(/DOPENCV_SIMD_CONFIG_HEADER=opencv_simd_config_custom.hpp)
+or
+    add_definitions(/DOPENCV_SIMD_CONFIG_INCLUDE_DIR=1)
+
+Additionally you may need to add include directory to your files:
+    include_directories("${CMAKE_CURRENT_LIST_DIR}/opencv_config_${MYTARGET}")
+
+These files can be pre-generated for target configurations of your application
+or generated by CMake on the fly (use CMAKE_BINARY_DIR for that).
+
+Notes:
+- H/W capability checks are still responsibility of your application
+- runtime dispatching is not covered by this helper header

+/** @addtogroup core_utils_softfloat
+
+  [SoftFloat](http://www.jhauser.us/arithmetic/SoftFloat.html) is a software implementation
+  of floating-point calculations according to IEEE 754 standard.
+  All calculations are done in integers, that's why they are machine-independent and bit-exact.
+  This library can be useful in accuracy-critical parts like look-up tables generation, tests, etc.
+  OpenCV contains a subset of SoftFloat partially rewritten to C++.
+
+  ### Types
+
+  There are two basic types: @ref softfloat and @ref softdouble.
+  These types are binary compatible with float and double types respectively
+  and support conversions to/from them.
+  Other types from original SoftFloat library like fp16 or fp128 were thrown away
+  as well as quiet/signaling NaN support, on-the-fly rounding mode switch
+  and exception flags (though exceptions can be implemented in the future).
+
+  ### Operations
+
+  Both types support the following:
+  - Construction from signed and unsigned 32-bit and 64 integers,
+  float/double or raw binary representation
+  - Conversions between each other, to float or double and to int
+  using @ref cvRound, @ref cvTrunc, @ref cvFloor, @ref cvCeil or a bunch of
+  saturate_cast functions
+  - Add, subtract, multiply, divide, remainder, square root, FMA with absolute precision
+  - Comparison operations
+  - Explicit sign, exponent and significand manipulation through get/set methods,
+ number state indicators (isInf, isNan, isSubnormal)
+  - Type-specific constants like eps, minimum/maximum value, best pi approximation, etc.
+  - min(), max(), abs(), exp(), log() and pow() functions

+/** @brief Template "trait" class for OpenCV primitive data types.
+
+@note Deprecated. This is replaced by "single purpose" traits: traits::Type and traits::Depth
+
+A primitive OpenCV data type is one of unsigned char, bool, signed char, unsigned short, signed
+short, int, float, double, or a tuple of values of one of these types, where all the values in the
+tuple have the same type. Any primitive type from the list can be defined by an identifier in the
+form CV_\<bit-depth\>{U|S|F}C(\<number_of_channels\>), for example: uchar \~ CV_8UC1, 3-element
+floating-point tuple \~ CV_32FC3, and so on. A universal OpenCV structure that is able to store a
+single instance of such a primitive data type is Vec. Multiple instances of such a type can be
+stored in a std::vector, Mat, Mat_, SparseMat, SparseMat_, or any other container that is able to
+store Vec instances.
+
+The DataType class is basically used to provide a description of such primitive data types without
+adding any fields or methods to the corresponding classes (and it is actually impossible to add
+anything to primitive C/C++ data types). This technique is known in C++ as class traits. It is not
+DataType itself that is used but its specialized versions, such as:
+@code
+    template<> class DataType<uchar>
+    {
+        typedef uchar value_type;
+        typedef int work_type;
+        typedef uchar channel_type;
+        enum { channel_type = CV_8U, channels = 1, fmt='u', type = CV_8U };
+    };
+    ...
+    template<typename _Tp> DataType<std::complex<_Tp> >
+    {
+        typedef std::complex<_Tp> value_type;
+        typedef std::complex<_Tp> work_type;
+        typedef _Tp channel_type;
+        // DataDepth is another helper trait class
+        enum { depth = DataDepth<_Tp>::value, channels=2,
+            fmt=(channels-1)*256+DataDepth<_Tp>::fmt,
+            type=CV_MAKETYPE(depth, channels) };
+    };
+    ...
+@endcode
+The main purpose of this class is to convert compilation-time type information to an
+OpenCV-compatible data type identifier, for example:
+@code
+    // allocates a 30x40 floating-point matrix
+    Mat A(30, 40, DataType<float>::type);
+
+    Mat B = Mat_<std::complex<double> >(3, 3);
+    // the statement below will print 6, 2 , that is depth == CV_64F, channels == 2
+    cout << B.depth() << ", " << B.channels() << endl;
+@endcode
+So, such traits are used to tell OpenCV which data type you are working with, even if such a type is
+not native to OpenCV. For example, the matrix B initialization above is compiled because OpenCV
+defines the proper specialized template class DataType\<complex\<_Tp\> \> . This mechanism is also
+useful (and used in OpenCV this way) for generic algorithms implementations.
+
+@note Default values were dropped to stop confusing developers about using of unsupported types (see #7599)

+//////////////////////////////// Rect_ ////////////////////////////////
+
+/** @brief Template class for 2D rectangles
+
+described by the following parameters:
+-   Coordinates of the top-left corner. This is a default interpretation of Rect_::x and Rect_::y
+    in OpenCV. Though, in your algorithms you may count x and y from the bottom-left corner.
+-   Rectangle width and height.
+
+OpenCV typically assumes that the top and left boundary of the rectangle are inclusive, while the
+right and bottom boundaries are not. For example, the method Rect_::contains returns true if
+
+\f[x  \leq pt.x < x+width,
+      y  \leq pt.y < y+height\f]
+
+Virtually every loop over an image ROI in OpenCV (where ROI is specified by Rect_\<int\> ) is
+implemented as:
+@code
+    for(int y = roi.y; y < roi.y + roi.height; y++)
+        for(int x = roi.x; x < roi.x + roi.width; x++)
+        {
+            // ...
+        }
+@endcode
+In addition to the class members, the following operations on rectangles are implemented:
+-   \f$\texttt{rect} = \texttt{rect} \pm \texttt{point}\f$ (shifting a rectangle by a certain offset)
+-   \f$\texttt{rect} = \texttt{rect} \pm \texttt{size}\f$ (expanding or shrinking a rectangle by a
+    certain amount)
+-   rect += point, rect -= point, rect += size, rect -= size (augmenting operations)
+-   rect = rect1 & rect2 (rectangle intersection)
+-   rect = rect1 | rect2 (minimum area rectangle containing rect1 and rect2 )
+-   rect &= rect1, rect |= rect1 (and the corresponding augmenting operations)
+-   rect == rect1, rect != rect1 (rectangle comparison)
+
+This is an example how the partial ordering on rectangles can be established (rect1 \f$\subseteq\f$
+rect2):
+@code
+    template<typename _Tp> inline bool
+    operator <= (const Rect_<_Tp>& r1, const Rect_<_Tp>& r2)
+    {
+        return (r1 & r2) == r1;

+The spatial moments \f$\texttt{Moments::m}_{ji}\f$ are computed as:
+
+\f[\texttt{m} _{ji}= \sum _{x,y}  \left ( \texttt{array} (x,y)  \cdot x^j  \cdot y^i \right )\f]
+
+The central moments \f$\texttt{Moments::mu}_{ji}\f$ are computed as:
+
+\f[\texttt{mu} _{ji}= \sum _{x,y}  \left ( \texttt{array} (x,y)  \cdot (x -  \bar{x} )^j  \cdot (y -  \bar{y} )^i \right )\f]
+
+where \f$(\bar{x}, \bar{y})\f$ is the mass center:
+
+\f[\bar{x} = \frac{\texttt{m}_{10}}{\texttt{m}_{00}} , \; \bar{y} = \frac{\texttt{m}_{01}}{\texttt{m}_{00}}\f]
+
+The normalized central moments \f$\texttt{Moments::nu}_{ij}\f$ are computed as:
+
+\f[\texttt{nu} _{ji}= \frac{\texttt{mu}_{ji}}{\texttt{m}_{00}^{(i+j)/2+1}} .\f]
+
+@note
+\f$\texttt{mu}_{00}=\texttt{m}_{00}\f$, \f$\texttt{nu}_{00}=1\f$
+\f$\texttt{nu}_{10}=\texttt{mu}_{10}=\texttt{mu}_{01}=\texttt{mu}_{10}=0\f$ , hence the values are not
+stored.
+
+The moments of a contour are defined in the same way but computed using the Green's formula (see
+<http://en.wikipedia.org/wiki/Green_theorem>). So, due to a limited raster resolution, the moments
+computed for a contour are slightly different from the moments computed for the same rasterized
+contour.
+
+@note
+Since the contour moments are computed using Green formula, you may get seemingly odd results for
+contours with self-intersections, e.g. a zero area (m00) for butterfly-shaped contours.

+/** @brief  Automatically Allocated Buffer Class
+
+ The class is used for temporary buffers in functions and methods.
+ If a temporary buffer is usually small (a few K's of memory),
+ but its size depends on the parameters, it makes sense to create a small
+ fixed-size array on stack and use it if it's large enough. If the required buffer size
+ is larger than the fixed size, another buffer of sufficient size is allocated dynamically
+ and released after the processing. Therefore, in typical cases, when the buffer size is small,
+ there is no overhead associated with malloc()/free().
+ At the same time, there is no limit on the size of processed data.
+
+ This is what AutoBuffer does. The template takes 2 parameters - type of the buffer elements and
+ the number of stack-allocated elements. Here is how the class is used:
+
+ \code
+ void my_func(const cv::Mat& m)
+ {
+    cv::AutoBuffer<float> buf(1000); // create automatic buffer containing 1000 floats
+
+    buf.allocate(m.rows); // if m.rows <= 1000, the pre-allocated buffer is used,
+                          // otherwise the buffer of "m.rows" floats will be allocated
+                          // dynamically and deallocated in cv::AutoBuffer destructor
+    ...
+ }
+ \endcode

+/** @brief Designed for command line parsing
+
+The sample below demonstrates how to use CommandLineParser:
+@code
+    CommandLineParser parser(argc, argv, keys);
+    parser.about("Application name v1.0.0");
+
+    if (parser.has("help"))
+    {
+        parser.printMessage();
+        return 0;
+    }
+
+    int N = parser.get<int>("N");
+    double fps = parser.get<double>("fps");
+    String path = parser.get<String>("path");
+
+    use_time_stamp = parser.has("timestamp");
+
+    String img1 = parser.get<String>(0);
+    String img2 = parser.get<String>(1);
+
+    int repeat = parser.get<int>(2);
+
+    if (!parser.check())
+    {
+        parser.printErrors();
+        return 0;
+    }
+@endcode
+
+### Keys syntax
+
+The keys parameter is a string containing several blocks, each one is enclosed in curly braces and
+describes one argument. Each argument contains three parts separated by the `|` symbol:
+
+-# argument names is a space-separated list of option synonyms (to mark argument as positional, prefix it with the `@` symbol)
+-# default value will be used if the argument was not provided (can be empty)
+-# help message (can be empty)
+
+For example:
+
+@code{.cpp}
+    const String keys =
+        "{help h usage ? |      | print this message   }"
+        "{@image1        |      | image1 for compare   }"
+        "{@image2        |<none>| image2 for compare   }"
+        "{@repeat        |1     | number               }"
+        "{path           |.     | path to file         }"
+        "{fps            | -1.0 | fps for output video }"
+        "{N count        |100   | count of objects     }"
+        "{ts timestamp   |      | use time stamp       }"
+        ;
+}
+@endcode
+
+Note that there are no default values for `help` and `timestamp` so we can check their presence using the `has()` method.
+Arguments with default values are considered to be always present. Use the `get()` method in these cases to check their
+actual value instead.
+
+String keys like `get<String>("@image1")` return the empty string `""` by default - even with an empty default value.
+Use the special `<none>` default value to enforce that the returned string must not be empty. (like in `get<String>("@image2")`)
+
+### Usage
+
+For the described keys:
+
+@code{.sh}
+    # Good call (3 positional parameters: image1, image2 and repeat; N is 200, ts is true)
+    $ ./app -N=200 1.png 2.jpg 19 -ts
+
+    # Bad call
+    $ ./app -fps=aaa
+    ERRORS:
+    Parameter 'fps': can not convert: [aaa] to [double]

+- VA_INTEL_IOCL_ROOT for Intel OpenCL (default is "/opt/intel/opencl").

+  This subsection of dnn module contains information about built-in layers and their descriptions.
+
+  Classes listed here, in fact, provides C++ API for creating instances of built-in layers.
+  In addition to this way of layers instantiation, there is a more common factory API (see @ref dnnLayerFactory), it allows to create layers dynamically (by name) and register new ones.
+  You can use both API, but factory API is less convenient for native C++ programming and basically designed for use inside importers (see @ref readNetFromCaffe(), @ref readNetFromTorch(), @ref readNetFromTensorflow()).
+
+  Built-in layers partially reproduce functionality of corresponding Caffe and Torch7 layers.
+  In particular, the following layers and Caffe importer were tested to reproduce <a href="http://caffe.berkeleyvision.org/tutorial/layers.html">Caffe</a> functionality:
+  - Convolution
+  - Deconvolution
+  - Pooling

+        Than current output and current cell state is computed as follows:

+    will degrade feature matching scores dramatically. On the other hand, too close to 1 scale factor
+    will mean that to cover certain scale range you will need more pyramid levels and so the speed
+    will suffer.
+    @param nlevels The number of pyramid levels. The smallest level will have linear size equal to
+    input_image_linear_size/pow(scaleFactor, nlevels - firstLevel).
+    @param edgeThreshold This is size of the border where the features are not detected. It should
+    roughly match the patchSize parameter.
+    @param firstLevel The level of pyramid to put source image to. Previous layers are filled
+    with upscaled source image.
+    @param WTA_K The number of points that produce each element of the oriented BRIEF descriptor. The
+    default value 2 means the BRIEF where we take a random point pair and compare their brightnesses,
+    so we get 0/1 response. Other possible values are 3 and 4. For example, 3 means that we take 3
+    random points (of course, those point coordinates are random, but they are generated from the
+    pre-defined seed, so each element of BRIEF descriptor is computed deterministically from the pixel
+    rectangle), find point of maximum brightness and output index of the winner (0, 1 or 2). Such
+    output will occupy 2 bits, and therefore it will need a special variant of Hamming distance,
+    denoted as NORM_HAMMING2 (2 bits per bin). When WTA_K=4, we take 4 random points to compute each
+    bin (that will also occupy 2 bits with possible values 0, 1, 2 or 3).
+    @param scoreType The default HARRIS_SCORE means that Harris algorithm is used to rank features
+    (the score is written to KeyPoint::score and is used to retain best nfeatures features);
+    FAST_SCORE is alternative value of the parameter that produces slightly less stable keypoints,
+    but it is a little faster to compute.
+    @param patchSize size of the patch used by the oriented BRIEF descriptor. Of course, on smaller

+
+The class implements a simple algorithm for extracting blobs from an image:
+
+1.  Convert the source image to binary images by applying thresholding with several thresholds from
+    minThreshold (inclusive) to maxThreshold (exclusive) with distance thresholdStep between
+    neighboring thresholds.
+2.  Extract connected components from every binary image by findContours and calculate their
+    centers.
+3.  Group centers from several binary images by their coordinates. Close centers form one group that
+    corresponds to one blob, which is controlled by the minDistBetweenBlobs parameter.
+4.  From the groups, estimate final centers of blobs and their radiuses and return as locations and
+    sizes of keypoints.
+
+This class performs several filtrations of returned blobs. You should set filterBy\* to true/false
+to turn on/off corresponding filtration. Available filtrations:
+
+-   **By color**. This filter compares the intensity of a binary image at the center of a blob to
+blobColor. If they differ, the blob is filtered out. Use blobColor = 0 to extract dark blobs
+and blobColor = 255 to extract light blobs.
+-   **By area**. Extracted blobs have an area between minArea (inclusive) and maxArea (exclusive).
+-   **By circularity**. Extracted blobs have circularity
+(\f$\frac{4*\pi*Area}{perimeter * perimeter}\f$) between minCircularity (inclusive) and
+maxCircularity (exclusive).
+-   **By ratio of the minimum inertia to maximum inertia**. Extracted blobs have this ratio
+between minInertiaRatio (inclusive) and maxInertiaRatio (exclusive).
+-   **By convexity**. Extracted blobs have convexity (area / area of blob convex hull) between
+minConvexity (inclusive) and maxConvexity (exclusive).
+
+Default values of parameters are tuned to extract dark circular blobs.

+/** @brief The FLANN nearest neighbor index class. This class is templated with the type of elements for which
+the index is built.
+
+`Distance` functor specifies the metric to be used to calculate the distance between two points.
+There are several `Distance` functors that are readily available:
+
+cv::cvflann::L2_Simple - Squared Euclidean distance functor.
+This is the simpler, unrolled version. This is preferable for very low dimensionality data (eg 3D points)
+
+cv::flann::L2 - Squared Euclidean distance functor, optimized version.
+
+cv::flann::L1 - Manhattan distance functor, optimized version.
+
+cv::flann::MinkowskiDistance -  The Minkowsky distance functor.
+This is highly optimised with loop unrolling.
+The computation of squared root at the end is omitted for efficiency.
+
+cv::flann::MaxDistance - The max distance functor. It computes the
+maximum distance between two vectors. This distance is not a valid kdtree distance, it's not
+dimensionwise additive.
+
+cv::flann::HammingLUT -  %Hamming distance functor. It counts the bit
+differences between two strings using a lookup table implementation.
+
+cv::flann::Hamming - %Hamming distance functor. Population count is
+performed using library calls, if available. Lookup table implementation is used as a fallback.
+
+cv::flann::Hamming2 - %Hamming distance functor. Population count is
+implemented in 12 arithmetic operations (one of which is multiplication).
+
+cv::flann::HistIntersectionDistance - The histogram
+intersection distance functor.
+
+cv::flann::HellingerDistance - The Hellinger distance functor.
+
+cv::flann::ChiSquareDistance - The chi-square distance functor.
+
+cv::flann::KL_Divergence - The Kullback-Leibler divergence functor.
+
+Although the provided implementations cover a vast range of cases, it is also possible to use
+a custom implementation. The distance functor is a class whose `operator()` computes the distance
+between two features. If the distance is also a kd-tree compatible distance, it should also provide an
+`accum_dist()` method that computes the distance between individual feature dimensions.
+
+In addition to `operator()` and `accum_dist()`, a distance functor should also define the
+`ElementType` and the `ResultType` as the types of the elements it operates on and the type of the
+result it computes. If a distance functor can be used as a kd-tree distance (meaning that the full
+distance between a pair of features can be accumulated from the partial distances between the
+individual dimensions) a typedef `is_kdtree_distance` should be present inside the distance functor.
+If the distance is not a kd-tree distance, but it's a distance in a vector space (the individual
+dimensions of the elements it operates on can be accessed independently) a typedef
+`is_vector_space_distance` should be defined inside the functor. If neither typedef is defined, the
+distance is assumed to be a metric distance and will only be used with indexes operating on
+generic metric distances.

+ * GCompiled is very similar to `std::function<>` in its semantics --

+ * At the moment, GCompiled objects are not reentrant -- generally,

+/**
+ * @brief GComputation class represents a captured computation
+ * graph. GComputation objects form boundaries for expression code
+ * user writes with G-API, allowing to compile and execute it.
+ *
+ * G-API computations are defined with input/output data
+ * objects. G-API will track automatically which operations connect
+ * specified outputs to the inputs, forming up a call graph to be
+ * executed. The below example expresses calculation of Sobel operator
+ * for edge detection (\f$G = \sqrt{G_x^2 + G_y^2}\f$):
+ *
+ * @snippet modules/gapi/samples/api_ref_snippets.cpp graph_def
+ *
+ * Full pipeline can be now captured with this object declaration:
+ *
+ * @snippet modules/gapi/samples/api_ref_snippets.cpp graph_cap_full
+ *
+ * Input/output data objects on which a call graph should be
+ * reconstructed are passed using special wrappers cv::GIn and
+ * cv::GOut. G-API will track automatically which operations form a
+ * path from inputs to outputs and build the execution graph appropriately.
+ *
+ * Note that cv::GComputation doesn't take ownership on data objects
+ * it is defined. Moreover, multiple GComputation objects may be
+ * defined on the same expressions, e.g. a smaller pipeline which
+ * expects that image gradients are already pre-calculated may be
+ * defined like this:
+ *
+ * @snippet modules/gapi/samples/api_ref_snippets.cpp graph_cap_sub
+ *
+ * The resulting graph would expect two inputs and produce one
+ * output. In this case, it doesn't matter if gx/gy data objects are
+ * results of cv::gapi::Sobel operators -- G-API will stop unrolling
+ * expressions and building the underlying graph one reaching this
+ * data objects.
+ *
+ * The way how GComputation is defined is important as its definition
+ * specifies graph _protocol_ -- the way how the graph should be
+ * used. Protocol is defined by number of inputs, number of outputs,
+ * and shapes of inputs and outputs.
+ *
+ * In the above example, sobelEdge expects one Mat on input and
+ * produces one Mat; while sobelEdgeSub expects two Mats on input and
+ * produces one Mat. GComputation's protocol defines how other
+ * computation methods should be used -- cv::GComputation::compile() and
+ * cv::GComputation::apply(). For example, if a graph is defined on
+ * two GMat inputs, two cv::Mat objects have to be passed to apply()
+ * for execution. GComputation checks protocol correctness in runtime
+ * so passing a different number of objects in apply() or passing
+ * cv::Scalar instead of cv::Mat there would compile well as a C++
+ * source but raise an exception in run-time. G-API also comes with a
+ * typed wrapper cv::GComputationT<> which introduces this type-checking in
+ * compile-time.
+ *
+ * cv::GComputation itself is a thin object which just captures what
+ * the graph is. The compiled graph (which actually process data) is
+ * represented by class GCompiled. Use compile() method to generate a
+ * compiled graph with given compile options. cv::GComputation can
+ * also be used to process data with implicit graph compilation
+ * on-the-fly, see apply() for details.
+ *
+ * GComputation is a reference-counted object -- once defined, all its
+ * copies will refer to the same instance.

+ * @brief Represents a computation (graph) compiled for streaming.
+ *
+ * This class represents a product of graph compilation (calling
+ * cv::GComputation::compileStreaming()). Objects of this class
+ * actually do stream processing, and the whole pipeline execution
+ * complexity is incapsulated into objects of this class. Execution
+ * model has two levels: at the very top, the execution of a
+ * heterogeneous graph is aggressively pipelined; at the very bottom
+ * the execution of every internal block is determined by its
+ * associated backend. Backends are selected based on kernel packages
+ * passed via compilation arguments ( see @ref gapi_compile_args,
+ * GNetworkPackage, GKernelPackage for details).
+ *
+ * GStreamingCompiled objects have a "player" semantics -- there are
+ * methods like start() and stop(). GStreamingCompiled has a full
+ * control over a videostream and so is stateful. You need to specify the
+ * input stream data using setSource() and then call start() to
+ * actually start processing. After that, use pull() or try_pull() to
+ * obtain next processed data frame from the graph in a blocking or
+ * non-blocking way, respectively.
+ *
+ * Currently a single GStreamingCompiled can process only one video
+ * streat at time. Produce multiple GStreamingCompiled objects to run the
+ * same graph on multiple video streams.

+     * Input vectors must have the same number of elements as defined

+     *
+     * In contrast with regular GCompiled, user can also pass an
+     * object of type GVideoCapture for a GMat parameter of the parent
+     * GComputation.  The compiled pipeline will start fetching data

+     * Passing a regular Mat for a GMat parameter makes it "infinite"

+    //   template G-classes, calls custom wrap() from Traits.
+    //   The value returned by wrap() is then wrapped into GArg() and
+    //   stored in G-API metadata.
+    //
+    //   Example:
+    //   - cv::GMat arguments are passed as-is.
+    //   - integers, pointers, STL containers, user types are passed as-is.
+    //   - cv::GArray<T> is converted to cv::GArrayU.

+    //
+    //   - For "simple" (non-template) G-types, returns value as-is.
+    //     Example: cv::GMat has host type cv::Mat, when user passes a
+    //              cv::Mat, system stores it internally as cv::Mat.
+    //
+    //   - For "complex" (template) G-types, utilizes custom
+    //     wrap_in()/wrap_out() as described in Traits.

+/**
+ * @brief This class is a typed wrapper over a regular GComputation.
+ *
+ * `std::function<>`-like template parameter specifies the graph
+ *  signature so methods so the object's constructor, methods like
+ *  `apply()` and the derived `GCompiledT::operator()` also become
+ *  typed.
+ *
+ *  There is no need to use cv::gin() or cv::gout() modifiers with
+ *  objects of this class.  Instead, all input arguments are followed
+ *  by all output arguments in the order from the template argument
+ *  signature.
+ *
+ *  Refer to the following example. Regular (untyped) code is written this way:
+ *
+ *  @snippet modules/gapi/samples/api_ref_snippets.cpp Untyped_Example
+ *
+ *  Here:
+ *
+ *  - cv::GComputation object is created with a lambda constructor
+ *    where it is defined as a two-input, one-output graph.
+ *
+ *  - Its method `apply()` in fact takes arbitrary number of arguments
+ *    (as vectors) so user can pass wrong number of inputs/outputs
+ *    here. C++ compiler wouldn't notice that since the cv::GComputation
+ *    API is polymorphic, and only a run-time error will be generated.
+ *
+ *  Now the same code written with typed API:
+ *
+ *  @snippet modules/gapi/samples/api_ref_snippets.cpp Typed_Example
+ *
+ *  The key difference is:
+ *
+ *  - Now the constructor lambda *must take* parameters and *must
+ *    return* values as defined in the `GComputationT<>` signature.
+ *  - Its method `apply()` does not require any extra specifiers to
+ *    separate input arguments from the output ones
+ *  - A `GCompiledT` (compilation product) takes input/output
+ *    arguments with no extra specifiers as well.

+ *  @{
+ *
+ *  @brief Functions for in-graph drawing.
+ *
+ *  @note This is a Work in Progress functionality and APIs may
+ *  change in the future releases.
+ *
+ *  G-API can do some in-graph drawing with a generic operations and a
+ *  set of [rendering primitives](@ref gapi_draw_prims).
+ *  In contrast with traditional OpenCV, in G-API user need to form a
+ *  *rendering list* of primitives to draw. This list can be built
+ *  manually or generated within a graph. This list is passed to
+ *  [special operations or functions](@ref gapi_draw_api) where all
+ *  primitives are interpreted and applied to the image.
+ *
+ *  For example, in a complex pipeline a list of detected objects
+ *  can be translated in-graph to a list of cv::gapi::wip::draw::Rect
+ *  primitives to highlight those with bounding boxes, or a list of
+ *  detected faces can be translated in-graph to a list of
+ *  cv::gapi::wip::draw::Mosaic primitives to hide sensitive content
+ *  or protect privacy.
+ *
+ *  Like any other operations, rendering in G-API can be reimplemented
+ *  by different backends. Currently only an OpenCV-based backend is
+ *  available.
+ *
+ *  In addition to the graph-level operations, there are also regular
+ *  (immediate) OpenCV-like functions are available -- see
+ *  cv::gapi::wip::draw::render(). These functions are just wrappers
+ *  over regular G-API and build the rendering graphs on the fly, so
+ *  take compilation arguments as parameters.
+ *
+ *  Currently this API is more machine-oriented than human-oriented.
+ *  The main purpose is to translate a set of domain-specific objects
+ *  to a list of primitives to draw. For example, in order to generate
+ *  a picture like this:
+ *
+ *  ![](modules/gapi/doc/pics/render_example.png)
+ *
+ *  Rendering list needs to be generated as follows:
+ *
+ *  @include modules/gapi/samples/draw_example.cpp
+ *
+ *  @defgroup gapi_draw_prims Drawing primitives
+ *  @defgroup gapi_draw_api Drawing operations and functions
+ *  @}

+@param prevImg first 8-bit input image (GMat) or pyramid (GArray<GMat>) constructed by
+buildOpticalFlowPyramid.
+@param nextImg second input image (GMat) or pyramid (GArray<GMat>) of the same size and the same
+type as prevImg.
+@param prevPts GArray of 2D points for which the flow needs to be found; point coordinates must be
+single-precision floating-point numbers.
+@param predPts GArray of 2D points initial for the flow search; make sense only when
+OPTFLOW_USE_INITIAL_FLOW flag is passed; in that case the vector must have the same size as in
+the input.
+@param winSize size of the search window at each pyramid level.
+@param maxLevel 0-based maximal pyramid level number; if set to 0, pyramids are not used (single
+level), if set to 1, two levels are used, and so on; if pyramids are passed to input then
+algorithm will use as many levels as pyramids have but no more than maxLevel.
+@param criteria parameter, specifying the termination criteria of the iterative search algorithm
+(after the specified maximum number of iterations criteria.maxCount or when the search window
+moves by less than criteria.epsilon).
+@param flags operation flags:
+ -   **OPTFLOW_USE_INITIAL_FLOW** uses initial estimations, stored in nextPts; if the flag is
+     not set, then prevPts is copied to nextPts and is considered the initial estimate.
+ -   **OPTFLOW_LK_GET_MIN_EIGENVALS** use minimum eigen values as an error measure (see
+     minEigThreshold description); if the flag is not set, then L1 distance between patches
+     around the original and a moved point, divided by number of pixels in a window, is used as a
+     error measure.
+@param minEigThresh the algorithm calculates the minimum eigen value of a 2x2 normal matrix of
+optical flow equations (this matrix is called a spatial gradient matrix in @cite Bouguet00), divided
+by number of pixels in a window; if this value is less than minEigThreshold, then a corresponding
+feature is filtered out and its flow is not processed, so it allows to remove bad points and get a
+performance boost.
+
+@return GArray of 2D points (with single-precision floating-point coordinates)
+containing the calculated new positions of input features in the second image.
+@return status GArray (of unsigned chars); each element of the vector is set to 1 if
+the flow for the corresponding features has been found, otherwise, it is set to 0.
+@return GArray of errors (doubles); each element of the vector is set to an error for the
+corresponding feature, type of the error measure can be set in flags parameter; if the flow wasn't
+found then the error is not defined (use the status parameter to find such cases).

+@defgroup highgui High-level GUI
+
+While OpenCV was designed for use in full-scale applications and can be used within functionally
+rich UI frameworks (such as Qt\*, WinForms\*, or Cocoa\*) or without any UI at all, sometimes there
+it is required to try functionality quickly and visualize the results. This is what the HighGUI
+module has been designed for.
+
+It provides easy interface to:
+
+-   Create and manipulate windows that can display images and "remember" their content (no need to
+    handle repaint events from OS).
+-   Add trackbars to the windows, handle simple mouse events as well as keyboard commands.
+
+@{
+    @defgroup highgui_opengl OpenGL support
+    @defgroup highgui_qt Qt New Functions
+
+    ![image](pics/qtgui.png)
+
+    This figure explains new functionality implemented with Qt\* GUI. The new GUI provides a statusbar,
+    a toolbar, and a control panel. The control panel can have trackbars and buttonbars attached to it.
+    If you cannot see the control panel, press Ctrl+P or right-click any Qt window and select **Display
+    properties window**.
+
+    -   To attach a trackbar, the window name parameter must be NULL.
+
+    -   To attach a buttonbar, a button must be created. If the last bar attached to the control panel
+        is a buttonbar, the new button is added to the right of the last button. If the last bar
+        attached to the control panel is a trackbar, or the control panel is empty, a new buttonbar is
+        created. Then, a new button is attached to it.
+
+    See below the example used to generate the figure:
+    @code
+        int main(int argc, char *argv[])
+        {
+
+            int value = 50;

+
+    This figure explains new functionality implemented with WinRT GUI. The new GUI provides an Image control,

+
+You can call cv::destroyWindow or cv::destroyAllWindows to close the window and de-allocate any associated

+ -   **WINDOW_FREERATIO or WINDOW_KEEPRATIO:** WINDOW_FREERATIO adjusts the image
+     with no respect to its ratio, whereas WINDOW_KEEPRATIO keeps the image ratio.
+ -   **WINDOW_GUI_NORMAL or WINDOW_GUI_EXPANDED:** WINDOW_GUI_NORMAL is the old way to draw the window
+     without statusbar and toolbar, whereas WINDOW_GUI_EXPANDED is a new enhanced GUI.
+By default, flags == WINDOW_AUTOSIZE | WINDOW_KEEPRATIO | WINDOW_GUI_EXPANDED

+Otherwise, the image is scaled to fit the window. The function may scale the image, depending on its depth:
+
+-   If the image is 8-bit unsigned, it is displayed as is.
+-   If the image is 16-bit unsigned or 32-bit integer, the pixels are divided by 256. That is, the

+-   If the image is 32-bit or 64-bit floating-point, the pixel values are multiplied by 255. That is, the
+    value range [0,1] is mapped to [0,255].
+
+If window was created with OpenGL support, cv::imshow also support ogl::Buffer , ogl::Texture2D and

+If the window was not created before this function, it is assumed creating a window with cv::WINDOW_AUTOSIZE.

+/** @brief Loads an image from a file.
+
+@anchor imread
+
+The function imread loads an image from the specified file and returns it. If the image cannot be
+read (because of missing file, improper permissions, unsupported or invalid format), the function
+returns an empty matrix ( Mat::data==NULL ).
+
+Currently, the following file formats are supported:
+
+-   Windows bitmaps - \*.bmp, \*.dib (always supported)
+-   JPEG files - \*.jpeg, \*.jpg, \*.jpe (see the *Note* section)
+-   JPEG 2000 files - \*.jp2 (see the *Note* section)
+-   Portable Network Graphics - \*.png (see the *Note* section)
+-   WebP - \*.webp (see the *Note* section)
+-   Portable image format - \*.pbm, \*.pgm, \*.ppm \*.pxm, \*.pnm (always supported)
+-   PFM files - \*.pfm (see the *Note* section)
+-   Sun rasters - \*.sr, \*.ras (always supported)
+-   TIFF files - \*.tiff, \*.tif (see the *Note* section)
+-   OpenEXR Image files - \*.exr (see the *Note* section)
+-   Radiance HDR - \*.hdr, \*.pic (always supported)
+-   Raster and Vector geospatial data supported by GDAL (see the *Note* section)
+
+@note
+-   The function determines the type of an image by the content, not by the file extension.
+-   In the case of color images, the decoded images will have the channels stored in **B G R** order.
+-   When using IMREAD_GRAYSCALE, the codec's internal grayscale conversion will be used, if available.
+    Results may differ to the output of cvtColor()
+-   On Microsoft Windows\* OS and MacOSX\*, the codecs shipped with an OpenCV image (libjpeg,
+    libpng, libtiff, and libjasper) are used by default. So, OpenCV can always read JPEGs, PNGs,
+    and TIFFs. On MacOSX, there is also an option to use native MacOSX image readers. But beware
+    that currently these native image loaders give images with different pixel values because of
+    the color management embedded into MacOSX.
+-   On Linux\*, BSD flavors and other Unix-like open-source operating systems, OpenCV looks for
+    codecs supplied with an OS image. Install the relevant packages (do not forget the development
+    files, for example, "libjpeg-dev", in Debian\* and Ubuntu\*) to get the codec support or turn
+    on the OPENCV_BUILD_3RDPARTY_LIBS flag in CMake.
+-   In the case you set *WITH_GDAL* flag to true in CMake and @ref IMREAD_LOAD_GDAL to load the image,
+    then the [GDAL](http://www.gdal.org) driver will be used in order to decode the image, supporting
+    the following formats: [Raster](http://www.gdal.org/formats_list.html),
+    [Vector](http://www.gdal.org/ogr_formats.html).
+-   If EXIF information is embedded in the image file, the EXIF orientation will be taken into account
+    and thus the image will be rotated accordingly except if the flags @ref IMREAD_IGNORE_ORIENTATION
+    or @ref IMREAD_UNCHANGED are passed.
+-   Use the IMREAD_UNCHANGED flag to keep the floating point values from PFM image.
+-   By default number of pixels must be less than 2^30. Limit can be set using system
+    variable OPENCV_IO_MAX_IMAGE_PIXELS
+

+
+/** @brief Saves an image to a specified file.
+
+The function imwrite saves the image to the specified file. The image format is chosen based on the
+filename extension (see cv::imread for the list of extensions). In general, only 8-bit
+single-channel or 3-channel (with 'BGR' channel order) images
+can be saved using this function, with these exceptions:
+
+- 16-bit unsigned (CV_16U) images can be saved in the case of PNG, JPEG 2000, and TIFF formats
+- 32-bit float (CV_32F) images can be saved in PFM, TIFF, OpenEXR, and Radiance HDR formats;
+  3-channel (CV_32FC3) TIFF images will be saved using the LogLuv high dynamic range encoding
+  (4 bytes per pixel)
+- PNG images with an alpha channel can be saved using this function. To do this, create
+8-bit (or 16-bit) 4-channel image BGRA, where the alpha channel goes last. Fully transparent pixels
+should have alpha set to 0, fully opaque pixels should have alpha set to 255/65535 (see the code sample below).
+- Multiple images (vector of Mat) can be saved in TIFF format (see the code sample below).
+
+If the format, depth or channel order is different, use
+Mat::convertTo and cv::cvtColor to convert it before saving. Or, use the universal FileStorage I/O
+functions to save the image to XML or YAML format.
+
+The sample below shows how to create a BGRA image, how to set custom compression parameters and save it to a PNG file.
+It also demonstrates how to save multiple images in a TIFF file:
+@include snippets/imgcodecs_imwrite.cpp
+@param filename Name of the file.
+@param img (Mat or vector of Mat) Image or Images to be saved.
+@param params Format-specific parameters encoded as pairs (paramId_1, paramValue_1, paramId_2, paramValue_2, ... .) see cv::ImwriteFlags
+*/
+CV_EXPORTS_W bool imwrite( const String& filename, InputArray img,
+              const std::vector<int>& params = std::vector<int>());
+
+/** @brief Reads an image from a buffer in memory.
+
+The function imdecode reads an image from the specified buffer in the memory. If the buffer is too short or
+contains invalid data, the function returns an empty matrix ( Mat::data==NULL ).
+

+  @defgroup imgproc Image Processing
+
+This module includes image-processing functions.
+
+  @{
+    @defgroup imgproc_filter Image Filtering
+
+Functions and classes described in this section are used to perform various linear or non-linear
+filtering operations on 2D images (represented as Mat's). It means that for each pixel location
+\f$(x,y)\f$ in the source image (normally, rectangular), its neighborhood is considered and used to
+compute the response. In case of a linear filter, it is a weighted sum of pixel values. In case of
+morphological operations, it is the minimum or maximum values, and so on. The computed response is
+stored in the destination image at the same location \f$(x,y)\f$. It means that the output image
+will be of the same size as the input image. Normally, the functions support multi-channel arrays,
+in which case every channel is processed independently. Therefore, the output image will also have
+the same number of channels as the input one.
+
+Another common feature of the functions and classes described in this section is that, unlike
+simple arithmetic functions, they need to extrapolate values of some non-existing pixels. For
+example, if you want to smooth an image using a Gaussian \f$3 \times 3\f$ filter, then, when
+processing the left-most pixels in each row, you need pixels to the left of them, that is, outside
+of the image. You can let these pixels be the same as the left-most image pixels ("replicated
+border" extrapolation method), or assume that all the non-existing pixels are zeros ("constant
+border" extrapolation method), and so on. OpenCV enables you to specify the extrapolation method.
+For details, see #BorderTypes
+
+@anchor filter_depths
+### Depth combinations
+Input depth (src.depth()) | Output depth (ddepth)
+--------------------------|----------------------
+CV_8U                     | -1/CV_16S/CV_32F/CV_64F
+CV_16U/CV_16S             | -1/CV_32F/CV_64F
+CV_32F                    | -1/CV_32F/CV_64F
+CV_64F                    | -1/CV_64F
+
+@note when ddepth=-1, the output image will have the same depth as the source.
+
+    @defgroup imgproc_transform Geometric Image Transformations
+
+The functions in this section perform various geometrical transformations of 2D images. They do not
+change the image content but deform the pixel grid and map this deformed grid to the destination
+image. In fact, to avoid sampling artifacts, the mapping is done in the reverse order, from
+destination to the source. That is, for each pixel \f$(x, y)\f$ of the destination image, the
+functions compute coordinates of the corresponding "donor" pixel in the source image and copy the
+pixel value:
+
+\f[\texttt{dst} (x,y)= \texttt{src} (f_x(x,y), f_y(x,y))\f]
+
+In case when you specify the forward mapping \f$\left<g_x, g_y\right>: \texttt{src} \rightarrow
+\texttt{dst}\f$, the OpenCV functions first compute the corresponding inverse mapping
+\f$\left<f_x, f_y\right>: \texttt{dst} \rightarrow \texttt{src}\f$ and then use the above formula.
+
+The actual implementations of the geometrical transformations, from the most generic remap and to
+the simplest and the fastest resize, need to solve two main problems with the above formula:
+
+- Extrapolation of non-existing pixels. Similarly to the filtering functions described in the
+previous section, for some \f$(x,y)\f$, either one of \f$f_x(x,y)\f$, or \f$f_y(x,y)\f$, or both
+of them may fall outside of the image. In this case, an extrapolation method needs to be used.
+OpenCV provides the same selection of extrapolation methods as in the filtering functions. In
+addition, it provides the method #BORDER_TRANSPARENT. This means that the corresponding pixels in
+the destination image will not be modified at all.
+
+- Interpolation of pixel values. Usually \f$f_x(x,y)\f$ and \f$f_y(x,y)\f$ are floating-point
+numbers. This means that \f$\left<f_x, f_y\right>\f$ can be either an affine or perspective
+transformation, or radial lens distortion correction, and so on. So, a pixel value at fractional
+coordinates needs to be retrieved. In the simplest case, the coordinates can be just rounded to the
+nearest integer coordinates and the corresponding pixel can be used. This is called a
+nearest-neighbor interpolation. However, a better result can be achieved by using more
+sophisticated [interpolation methods](http://en.wikipedia.org/wiki/Multivariate_interpolation) ,
+where a polynomial function is fit into some neighborhood of the computed pixel \f$(f_x(x,y),
+f_y(x,y))\f$, and then the value of the polynomial at \f$(f_x(x,y), f_y(x,y))\f$ is taken as the
+interpolated pixel value. In OpenCV, you can choose between several interpolation methods. See
+resize for details.
+
+@note The geometrical transformations do not work with `CV_8S` or `CV_32S` images.
+
+    @defgroup imgproc_misc Miscellaneous Image Transformations
+    @defgroup imgproc_draw Drawing Functions
+
+Drawing functions work with matrices/images of arbitrary depth. The boundaries of the shapes can be
+rendered with antialiasing (implemented only for 8-bit images for now). All the functions include
+the parameter color that uses an RGB value (that may be constructed with the Scalar constructor )
+for color images and brightness for grayscale images. For color images, the channel ordering is
+normally *Blue, Green, Red*. This is what imshow, imread, and imwrite expect. So, if you form a
+color using the Scalar constructor, it should look like:
+
+\f[\texttt{Scalar} (blue \_ component, green \_ component, red \_ component[, alpha \_ component])\f]
+
+If you are using your own image rendering and I/O functions, you can use any channel ordering. The
+drawing functions process each channel independently and do not depend on the channel order or even
+on the used color space. The whole image can be converted from BGR to RGB or to a different color
+space using cvtColor .
+
+If a drawn figure is partially or completely outside the image, the drawing functions clip it. Also,
+many drawing functions can handle pixel coordinates specified with sub-pixel accuracy. This means
+that the coordinates can be passed as fixed-point numbers encoded as integers. The number of
+fractional bits is specified by the shift parameter and the real point coordinates are calculated as
+\f$\texttt{Point}(x,y)\rightarrow\texttt{Point2f}(x*2^{-shift},y*2^{-shift})\f$ . This feature is
+especially effective when rendering antialiased shapes.
+
+@note The functions do not support alpha-transparency when the target image is 4-channel. In this
+case, the color[3] is simply copied to the repainted pixels. Thus, if you want to paint
+semi-transparent shapes, you can paint them in a separate buffer and then blend it with the main
+image.
+
+    @defgroup imgproc_color_conversions Color Space Conversions
+    @defgroup imgproc_colormap ColorMaps in OpenCV
+
+The human perception isn't built for observing fine changes in grayscale images. Human eyes are more
+sensitive to observing changes between colors, so you often need to recolor your grayscale images to
+get a clue about them. OpenCV now comes with various colormaps to enhance the visualization in your
+computer vision application.
+
+In OpenCV you only need applyColorMap to apply a colormap on a given image. The following sample
+code reads the path to an image from command line, applies a Jet colormap on it and shows the
+result:
+
+@include snippets/imgproc_applyColorMap.cpp
+
+@see #ColormapTypes
+
+    @defgroup imgproc_subdiv2d Planar Subdivision
+
+The Subdiv2D class described in this section is used to perform various planar subdivision on
+a set of 2D points (represented as vector of Point2f). OpenCV subdivides a plane into triangles
+using the Delaunay's algorithm, which corresponds to the dual graph of the Voronoi diagram.
+In the figure below, the Delaunay's triangulation is marked with black lines and the Voronoi
+diagram with red lines.
+
+![Delaunay triangulation (black) and Voronoi (red)](pics/delaunay_voronoi.png)
+
+The subdivisions can be used for the 3D piece-wise transformation of a plane, morphing, fast
+location of points on the plane, building special graphs (such as NNG,RNG), and so forth.

+
+The function finds circles in a grayscale image using a modification of the Hough transform.
+
+Example: :
+@include snippets/imgproc_HoughLinesCircles.cpp
+
+@note Usually the function detects the centers of circles well. However, it may fail to find correct
+radii. You can assist to the function by specifying the radius range ( minRadius and maxRadius ) if
+you know it. Or, in the case of #HOUGH_GRADIENT method you may set maxRadius to a negative number
+to return centers only without radius search, and find the correct radius using an additional procedure.
+
+It also helps to smooth image a bit unless it's already soft. For example,
+GaussianBlur() with 7x7 kernel and 1.5x1.5 sigma or similar blurring may help.
+
+@param image 8-bit, single-channel, grayscale input image.
+@param circles Output vector of found circles. Each vector is encoded as  3 or 4 element
+floating-point vector \f$(x, y, radius)\f$ or \f$(x, y, radius, votes)\f$ .
+@param method Detection method, see #HoughModes. The available methods are #HOUGH_GRADIENT and #HOUGH_GRADIENT_ALT.
+@param dp Inverse ratio of the accumulator resolution to the image resolution. For example, if
+dp=1 , the accumulator has the same resolution as the input image. If dp=2 , the accumulator has
+half as big width and height. For #HOUGH_GRADIENT_ALT the recommended value is dp=1.5,
+unless some small very circles need to be detected.
+@param minDist Minimum distance between the centers of the detected circles. If the parameter is
+too small, multiple neighbor circles may be falsely detected in addition to a true one. If it is
+too large, some circles may be missed.
+@param param1 First method-specific parameter. In case of #HOUGH_GRADIENT and #HOUGH_GRADIENT_ALT,
+it is the higher threshold of the two passed to the Canny edge detector (the lower one is twice smaller).
+Note that #HOUGH_GRADIENT_ALT uses #Scharr algorithm to compute image derivatives, so the threshold value
+shough normally be higher, such as 300 or normally exposed and contrasty images.
+@param param2 Second method-specific parameter. In case of #HOUGH_GRADIENT, it is the
+accumulator threshold for the circle centers at the detection stage. The smaller it is, the more
+false circles may be detected. Circles, corresponding to the larger accumulator values, will be
+returned first. In the case of #HOUGH_GRADIENT_ALT algorithm, this is the circle "perfectness" measure.
+The closer it to 1, the better shaped circles algorithm selects. In most cases 0.9 should be fine.
+If you want get better detection of small circles, you may decrease it to 0.85, 0.8 or even less.
+But then also try to limit the search range [minRadius, maxRadius] to avoid many false circles.
+@param minRadius Minimum circle radius.
+@param maxRadius Maximum circle radius. If <= 0, uses the maximum image dimension. If < 0, #HOUGH_GRADIENT returns
+centers without finding the radius. #HOUGH_GRADIENT_ALT always computes circle radiuses.

+
+Polar mapping can be linear or semi-log. Add one of #WarpPolarMode to `flags` to specify the polar mapping mode.

+dsize.area  \leftarrow (maxRadius^2 \cdot \Pi) \\
+dsize.width = \texttt{cvRound}(maxRadius) \\
+dsize.height = \texttt{cvRound}(maxRadius \cdot \Pi) \\
+\end{array}\f]
+
+
+- if only `dsize.height <= 0`,
+the destination image area will be proportional to the bounding circle area but scaled by `Kx * Kx`:
+\f[\begin{array}{l}
+dsize.height = \texttt{cvRound}(dsize.width \cdot \Pi) \\
+\end{array}
+\f]
+
+- if both values in `dsize > 0 `,
+the destination image will have the given size therefore the area of the bounding circle will be scaled to `dsize`.
+
+
+\par Reverse mapping
+
+You can get reverse mapping adding #WARP_INVERSE_MAP to `flags`

+
+In addiction, to calculate the original coordinate from a polar mapped coordinate \f$(rho, phi)->(x, y)\f$:

+\f[\sum _{x_1 \leq x < x_2,  \, y_1  \leq y < y_2}  \texttt{image} (x,y) =  \texttt{sum} (x_2,y_2)- \texttt{sum} (x_1,y_2)- \texttt{sum} (x_2,y_1)+ \texttt{sum} (x_1,y_1)\f]
+
+It makes possible to do a fast blurring or fast block correlation with a variable window size, for
+example. In case of multi-channel images, sums for each channel are accumulated independently.

+/** @brief Calculates the distance to the closest zero pixel for each pixel of the source image.
+
+The function cv::distanceTransform calculates the approximate or precise distance from every binary
+image pixel to the nearest zero pixel. For zero image pixels, the distance will obviously be zero.
+
+When maskSize == #DIST_MASK_PRECISE and distanceType == #DIST_L2 , the function runs the
+algorithm described in @cite Felzenszwalb04 . This algorithm is parallelized with the TBB library.
+
+In other cases, the algorithm @cite Borgefors86 is used. This means that for a pixel the function
+finds the shortest path to the nearest zero pixel consisting of basic shifts: horizontal, vertical,
+diagonal, or knight's move (the latest is available for a \f$5\times 5\f$ mask). The overall
+distance is calculated as a sum of these basic distances. Since the distance function should be
+symmetric, all of the horizontal and vertical shifts must have the same cost (denoted as a ), all
+the diagonal shifts must have the same cost (denoted as `b`), and all knight's moves must have the
+same cost (denoted as `c`). For the #DIST_C and #DIST_L1 types, the distance is calculated
+precisely, whereas for #DIST_L2 (Euclidean distance) the distance can be calculated only with a
+relative error (a \f$5\times 5\f$ mask gives more accurate results). For `a`,`b`, and `c`, OpenCV
+uses the values suggested in the original paper:
+- DIST_L1: `a = 1, b = 2`
+- DIST_L2:
+    - `3 x 3`: `a=0.955, b=1.3693`
+    - `5 x 5`: `a=1, b=1.4, c=2.1969`
+- DIST_C: `a = 1, b = 1`
+
+Typically, for a fast, coarse distance estimation #DIST_L2, a \f$3\times 3\f$ mask is used. For a
+more accurate distance estimation #DIST_L2, a \f$5\times 5\f$ mask or the precise algorithm is used.
+Note that both the precise and the approximate algorithms are linear on the number of pixels.
+
+This variant of the function does not only compute the minimum distance for each pixel \f$(x, y)\f$
+but also identifies the nearest connected component consisting of zero pixels
+(labelType==#DIST_LABEL_CCOMP) or the nearest zero pixel (labelType==#DIST_LABEL_PIXEL). Index of the
+component/pixel is stored in `labels(x, y)`. When labelType==#DIST_LABEL_CCOMP, the function
+automatically finds connected components of zero pixels in the input image and marks them with
+distinct labels. When labelType==#DIST_LABEL_CCOMP, the function scans through the input image and
+marks all the zero pixels with distinct labels.
+
+In this mode, the complexity is still linear. That is, the function provides a very fast way to
+compute the Voronoi diagram for a binary image. Currently, the second variant can use only the

+4 means that only the four nearest neighbor pixels (those that share an edge) are considered. A

+will be considered. The next 8 bits (8-16) contain a value between 1 and 255 with which to fill

+/** @brief Converts an image from one color space to another.
+
+The function converts an input image from one color space to another. In case of a transformation
+to-from RGB color space, the order of the channels should be specified explicitly (RGB or BGR). Note
+that the default color format in OpenCV is often referred to as RGB but it is actually BGR (the
+bytes are reversed). So the first byte in a standard (24-bit) color image will be an 8-bit Blue
+component, the second byte will be Green, and the third byte will be Red. The fourth, fifth, and
+sixth bytes would then be the second pixel (Blue, then Green, then Red), and so on.
+
+The conventional ranges for R, G, and B channel values are:
+-   0 to 255 for CV_8U images
+-   0 to 65535 for CV_16U images
+-   0 to 1 for CV_32F images
+
+In case of linear transformations, the range does not matter. But in case of a non-linear
+transformation, an input RGB image should be normalized to the proper value range to get the correct
+results, for example, for RGB \f$\rightarrow\f$ L\*u\*v\* transformation. For example, if you have a
+32-bit floating-point image directly converted from an 8-bit image without any scaling, then it will
+have the 0..255 value range instead of 0..1 assumed by the function. So, before calling #cvtColor ,
+you need first to scale the image down:
+@code
+    img *= 1./255;
+    cvtColor(img, img, COLOR_BGR2Luv);
+@endcode
+If you use #cvtColor with 8-bit images, the conversion will have some information lost. For many
+applications, this will not be noticeable but it is recommended to use 32-bit images in applications
+that need the full range of colors or that convert an image before an operation and then convert
+back.
+
+If conversion adds the alpha channel, its value will set to the maximum of corresponding channel
+range: 255 for CV_8U, 65535 for CV_16U, 1 for CV_32F.
+
+@param src input image: 8-bit unsigned, 16-bit unsigned ( CV_16UC... ), or single-precision

+ quadratics, parabolic and hyperbolic functions as well as elliptical functions as possible fits.
+ If the fit is found to be a parabolic or hyperbolic function then the standard #fitEllipse method is used.

+  categorical input variables), there is a little common ground between the classes. This common

+@brief Stochastic Gradient Descent SVM classifier
+
+SVMSGD provides a fast and easy-to-use implementation of the SVM classifier using the Stochastic Gradient Descent approach,
+as presented in @cite bottou2010large.
+
+The classifier has following parameters:
+- model type,
+- margin type,
+- margin regularization (\f$\lambda\f$),
+- initial step size (\f$\gamma_0\f$),
+- step decreasing power (\f$c\f$),
+- and termination criteria.
+
+The model type may have one of the following values: \ref SGD and \ref ASGD.
+
+- \ref SGD is the classic version of SVMSGD classifier: every next step is calculated by the formula
+  \f[w_{t+1} = w_t - \gamma(t) \frac{dQ_i}{dw} |_{w = w_t}\f]
+  where
+  - \f$w_t\f$ is the weights vector for decision function at step \f$t\f$,
+  - \f$\gamma(t)\f$ is the step size of model parameters at the iteration \f$t\f$, it is decreased on each step by the formula
+    \f$\gamma(t) = \gamma_0  (1 + \lambda  \gamma_0 t) ^ {-c}\f$
+  - \f$Q_i\f$ is the target functional from SVM task for sample with number \f$i\f$, this sample is chosen stochastically on each step of the algorithm.
+
+- \ref ASGD is Average Stochastic Gradient Descent SVM Classifier. ASGD classifier averages weights vector on each step of algorithm by the formula
+\f$\widehat{w}_{t+1} = \frac{t}{1+t}\widehat{w}_{t} + \frac{1}{1+t}w_{t+1}\f$
+
+The recommended model type is ASGD (following @cite bottou2010large).
+
+The margin type may have one of the following values: \ref SOFT_MARGIN or \ref HARD_MARGIN.
+
+- You should use \ref HARD_MARGIN type, if you have linearly separable sets.
+- You should use \ref SOFT_MARGIN type, if you have non-linearly separable sets or sets with outliers.
+- In the general case (if you know nothing about linear separability of your sets), use SOFT_MARGIN.
+
+The other parameters may be described as follows:
+- Margin regularization parameter is responsible for weights decreasing at each step and for the strength of restrictions on outliers
+  (the less the parameter, the less probability that an outlier will be ignored).
+  Recommended value for SGD model is 0.0001, for ASGD model is 0.00001.
+
+- Initial step size parameter is the initial value for the step size \f$\gamma(t)\f$.
+  You will have to find the best initial step for your problem.
+
+- Step decreasing power is the power parameter for \f$\gamma(t)\f$ decreasing by the formula, mentioned above.
+  Recommended value for SGD model is 1, for ASGD model is 0.75.
+
+- Termination criteria can be TermCriteria::COUNT, TermCriteria::EPS or TermCriteria::COUNT + TermCriteria::EPS.
+  You will have to find the best termination criteria for your problem.
+
+Note that the parameters margin regularization, initial step size, and step decreasing power should be positive.
+
+To use SVMSGD algorithm do as follows:
+
+- first, create the SVMSGD object. The algorithm will set optimal parameters by default, but you can set your own parameters via functions setSvmsgdType(),
+  setMarginType(), setMarginRegularization(), setInitialStepSize(), and setStepDecreasingPower().
+
+- then the SVM model can be trained using the train features and the correspondent labels by the method train().
+
+- after that, the label of a new feature vector can be predicted using the method predict().
+

+@defgroup objdetect Object Detection
+
+Haar Feature-based Cascade Classifier for Object Detection
+----------------------------------------------------------
+
+The object detector described below has been initially proposed by Paul Viola @cite Viola01 and
+improved by Rainer Lienhart @cite Lienhart02 .
+
+First, a classifier (namely a *cascade of boosted classifiers working with haar-like features*) is
+trained with a few hundred sample views of a particular object (i.e., a face or a car), called
+positive examples, that are scaled to the same size (say, 20x20), and negative examples - arbitrary
+images of the same size.
+
+After a classifier is trained, it can be applied to a region of interest (of the same size as used
+during the training) in an input image. The classifier outputs a "1" if the region is likely to show
+the object (i.e., face/car), and "0" otherwise. To search for the object in the whole image one can
+move the search window across the image and check every location using the classifier. The
+classifier is designed so that it can be easily "resized" in order to be able to find the objects of
+interest at different sizes, which is more efficient than resizing the image itself. So, to find an
+object of an unknown size in the image the scan procedure should be done several times at different
+scales.
+
+The word "cascade" in the classifier name means that the resultant classifier consists of several
+simpler classifiers (*stages*) that are applied subsequently to a region of interest until at some
+stage the candidate is rejected or all the stages are passed. The word "boosted" means that the
+classifiers at every stage of the cascade are complex themselves and they are built out of basic
+classifiers using one of four different boosting techniques (weighted voting). Currently Discrete
+Adaboost, Real Adaboost, Gentle Adaboost and Logitboost are supported. The basic classifiers are
+decision-tree classifiers with at least 2 leaves. Haar-like features are the input to the basic
+classifiers, and are calculated as described below. The current algorithm uses the following
+Haar-like features:
+
+![image](pics/haarfeatures.png)
+
+The feature used in a particular classifier is specified by its shape (1a, 2b etc.), position within
+the region of interest and the scale (this scale is not the same as the scale used at the detection
+stage, though these two scales are multiplied). For example, in the case of the third line feature
+(2c) the response is calculated as the difference between the sum of image pixels under the
+rectangle covering the whole feature (including the two white stripes and the black stripe in the
+middle) and the sum of the image pixels under the black stripe multiplied by 3 in order to
+compensate for the differences in the size of areas. The sums of pixel values over a rectangular
+regions are calculated rapidly using integral images (see below and the integral description).
+
+To see the object detector at work, have a look at the facedetect demo:
+<https://github.com/opencv/opencv/tree/master/samples/cpp/dbt_face_detection.cpp>
+
+The following reference is for the detection part only. There is a separate application called
+opencv_traincascade that can train a cascade of boosted classifiers from a set of samples.
+
+@note In the new C++ interface it is also possible to use LBP (local binary pattern) features in
+addition to Haar-like features. .. [Viola01] Paul Viola and Michael J. Jones. Rapid Object Detection
+using a Boosted Cascade of Simple Features. IEEE CVPR, 2001. The paper is available online at

+/** @brief Primal-dual algorithm is an algorithm for solving special types of variational problems (that is,
+finding a function to minimize some functional). As the image denoising, in particular, may be seen
+as the variational problem, primal-dual algorithm then can be used to perform denoising and this is
+exactly what is implemented.
+
+It should be noted, that this implementation was taken from the July 2013 blog entry
+@cite MA13 , which also contained (slightly more general) ready-to-use source code on Python.
+Subsequently, that code was rewritten on C++ with the usage of openCV by Vadim Pisarevsky at the end
+of July 2013 and finally it was slightly adapted by later authors.
+
+Although the thorough discussion and justification of the algorithm involved may be found in
+@cite ChambolleEtAl, it might make sense to skim over it here, following @cite MA13 . To begin
+with, we consider the 1-byte gray-level images as the functions from the rectangular domain of
+pixels (it may be seen as set
+\f$\left\{(x,y)\in\mathbb{N}\times\mathbb{N}\mid 1\leq x\leq n,\;1\leq y\leq m\right\}\f$ for some
+\f$m,\;n\in\mathbb{N}\f$) into \f$\{0,1,\dots,255\}\f$. We shall denote the noised images as \f$f_i\f$ and with
+this view, given some image \f$x\f$ of the same size, we may measure how bad it is by the formula
+
+\f[\left\|\left\|\nabla x\right\|\right\| + \lambda\sum_i\left\|\left\|x-f_i\right\|\right\|\f]
+
+\f$\|\|\cdot\|\|\f$ here denotes \f$L_2\f$-norm and as you see, the first addend states that we want our
+image to be smooth (ideally, having zero gradient, thus being constant) and the second states that
+we want our result to be close to the observations we've got. If we treat \f$x\f$ as a function, this is
+exactly the functional what we seek to minimize and here the Primal-Dual algorithm comes into play.
+
+@param observations This array should contain one or more noised versions of the image that is to
+be restored.
+@param result Here the denoised image will be stored. There is no need to do pre-allocation of
+storage space, as it will be automatically allocated, if necessary.
+@param lambda Corresponds to \f$\lambda\f$ in the formulas above. As it is enlarged, the smooth
+(blurred) images are treated more favorably than detailed (but maybe more noised) ones. Roughly
+speaking, as it becomes smaller, the result will be more blur but more sever outliers will be
+removed.
+@param niters Number of iterations that the algorithm will run. Of course, as more iterations as
+better, but it is hard to quantitatively refine this statement, so just use the default and
+increase it if the results are poor.

+@defgroup stitching Images stitching
+
+This figure illustrates the stitching module pipeline implemented in the Stitcher class. Using that
+class it's possible to configure/remove some steps, i.e. adjust the stitching pipeline according to
+the particular needs. All building blocks from the pipeline are available in the detail namespace,
+one can combine and use them separately.
+
+The implemented stitching pipeline is very similar to the one proposed in @cite BL07 .
+
+![stitching pipeline](StitchingPipeline.jpg)
+
+Camera models
+-------------
+
+There are currently 2 camera models implemented in stitching pipeline.
+
+- _Homography model_ expecting perspective transformations between images
+  implemented in @ref cv::detail::BestOf2NearestMatcher cv::detail::HomographyBasedEstimator
+  cv::detail::BundleAdjusterReproj cv::detail::BundleAdjusterRay
+- _Affine model_ expecting affine transformation with 6 DOF or 4 DOF implemented in
+  @ref cv::detail::AffineBestOf2NearestMatcher cv::detail::AffineBasedEstimator
+  cv::detail::BundleAdjusterAffine cv::detail::BundleAdjusterAffinePartial cv::AffineWarper
+
+Homography model is useful for creating photo panoramas captured by camera,
+while affine-based model can be used to stitch scans and object captured by
+specialized devices. Use @ref cv::Stitcher::create to get preconfigured pipeline for one
+of those models.
+
+@note
+Certain detailed settings of @ref cv::Stitcher might not make sense. Especially
+you should not mix classes implementing affine model and classes implementing
+Homography model, as they work with different transformations.

+single-precision floating-point numbers.
+@param nextPts output vector of 2D points (with single-precision floating-point coordinates)
+containing the calculated new positions of input features in the second image; when
+OPTFLOW_USE_INITIAL_FLOW flag is passed, the vector must have the same size as in the input.
+@param status output status vector (of unsigned chars); each element of the vector is set to 1 if
+the flow for the corresponding features has been found, otherwise, it is set to 0.
+@param err output vector of errors; each element of the vector is set to an error for the
+corresponding feature, type of the error measure can be set in flags parameter; if the flow wasn't
+found then the error is not defined (use the status parameter to find such cases).
+@param winSize size of the search window at each pyramid level.
+@param maxLevel 0-based maximal pyramid level number; if set to 0, pyramids are not used (single
+level), if set to 1, two levels are used, and so on; if pyramids are passed to input then
+algorithm will use as many levels as pyramids have but no more than maxLevel.
+@param criteria parameter, specifying the termination criteria of the iterative search algorithm
+(after the specified maximum number of iterations criteria.maxCount or when the search window
+moves by less than criteria.epsilon.
+@param flags operation flags:
+ -   **OPTFLOW_USE_INITIAL_FLOW** uses initial estimations, stored in nextPts; if the flag is
+     not set, then prevPts is copied to nextPts and is considered the initial estimate.
+ -   **OPTFLOW_LK_GET_MIN_EIGENVALS** use minimum eigen values as an error measure (see
+     minEigThreshold description); if the flag is not set, then L1 distance between patches
+     around the original and a moved point, divided by number of pixels in a window, is used as a
+     error measure.
+@param minEigThreshold the algorithm calculates the minimum eigen value of a 2x2 normal matrix of
+optical flow equations (this matrix is called a spatial gradient matrix in @cite Bouguet00), divided
+by number of pixels in a window; if this value is less than minEigThreshold, then a corresponding
+feature is filtered out and its flow is not processed, so it allows to remove bad points and get a
+performance boost.
+
+The function implements a sparse iterative version of the Lucas-Kanade optical flow in pyramids. See
+@cite Bouguet00 . The function is parallelized with the TBB library.

+@param winsize averaging window size; larger values increase the algorithm robustness to image
+noise and give more chances for fast motion detection, but yield more blurred motion field.
+@param iterations number of iterations the algorithm does at each pyramid level.
+@param poly_n size of the pixel neighborhood used to find polynomial expansion in each pixel;

+@param poly_sigma standard deviation of the Gaussian that is used to smooth derivatives used as a

+ -   **OPTFLOW_USE_INITIAL_FLOW** uses the input flow as an initial flow approximation.
+ -   **OPTFLOW_FARNEBACK_GAUSSIAN** uses the Gaussian \f$\texttt{winsize}\times\texttt{winsize}\f$
+     filter instead of a box filter of the same size for optical flow estimation; usually, this
+     option gives z more accurate flow than with a box filter, at the cost of lower speed;
+     normally, winsize for a Gaussian window should be set to a larger value to achieve the same

+(e.g., a simple euclidean/similarity transform that allows for the images showing the same image
+content approximately). Use inverse warping in the second image to take an image close to the first
+one, i.e. use the flag WARP_INVERSE_MAP with warpAffine or warpPerspective. See also the OpenCV

+    the case of success.
+
+    The primary use of the function is in multi-camera environments, especially when the cameras do not
+    have hardware synchronization. That is, you call VideoCapture::grab() for each camera and after that
+    call the slower method VideoCapture::retrieve() to decode and get frame from each camera. This way
+    the overhead on demosaicing or motion jpeg decompression etc. is eliminated and the retrieved frames
+    from different cameras will be closer in time.
+
+    Also, when a connected camera is multi-head (for example, a stereo camera or a Kinect device), the
+    correct way of retrieving data from it is to call VideoCapture::grab() first and then call
+    VideoCapture::retrieve() one or more times with different values of the channel parameter.
