+Seamless Cloning
+================
+
+.. highlight:: cpp
+
+seamlessClone
+-------------
+Image editing tasks concern either global changes (color/intensity corrections, filters, deformations) or local changes concerned to a selection.
+Here we are interested in achieving local changes, ones that are restricted to a region manually selected (ROI), in a seamless and effortless manner.
+The extent of the changes ranges from slight distortions to complete replacement by novel content.
+
+.. ocv:function:: void seamlessClone( InputArray src, InputArray dst, InputArray mask, Point p, OutputArray result, int flags)
+
+    :param src: Input 8-bit 3-channel image.
+
+    :param dst: Input 8-bit 3-channel image.
+    
+    :param mask: Input 8-bit 1 or 3-channel image.
+    
+    :param Point: Point in dst image where object is placed.
+    
+    :param result: Output image with the same size and type as ``dst``.
+
+    :param flags: Cloning method that could be one of the following:
+
+            * **NORMAL_CLONE**     The power of the method is fully expressed when inserting objects with complex outlines into a new background
+
+            * **MIXED_CLONE**    The classic method, color-based selection and alpha
+                                 masking might be time consuming and often leaves an undesirable halo. Seamless
+                                 cloning, even averaged with the original image, is not effective. Mixed seamless
+                                 cloning based on a loose selection proves effective.
+            
+            * **FEATURE_EXCHANGE**     Feature exchange allows the user to replace easily certain
+                                       features of one object by alternative features.
+
+
+
+colorChange
+-----------
+Given an original color image, two differently colored versions of this image can be mixed seamlessly.
+
+.. ocv:function:: void colorChange( InputArray src, OutputArray dst, float red = 1.0, float green = 1.0, float blue = 1.0)
+
+    :param src: Input 8-bit 3-channel image.
+
+    :param dst: Output image with the same size and type as  ``src`` .
+
+    :param red: R-channel Value
+    
+    :param green: G-channel Value
+    
+    :param blue: B-channel Value
+
+RGB values between .5 to 2.5
+    
+
+illuminationChange
+------------------
+Applying an appropriate non-linear transformation to the gradient field inside the selection and then integrating back with a Poisson
+solver, modifies locally the apparent illumination of an image.
+
+.. ocv:function:: void illuminationChange(InputArray src, OutputArray dst, float alpha = 0.2, float beta = 0.4)
+
+    :param src: Input 8-bit 3-channel image.
+
+    :param dst: Output image with the same size and type as  ``src``.
+
+    :param alpha: Value ranges between 0-2.
+    
+    :param beta: Value ranges between 0-2.
+
+This is useful to highlight under-exposed foreground objects or to reduce specular reflections.
+
+textureFlattening
+-----------------
+By retaining only the gradients at edge locations, before integrating with the Poisson solver, one washes out the texture of the selected
+region, giving its contents a flat aspect.
+
+.. ocv:function:: void textureFlattening(InputArray src, OutputArray dst)
+
+    :param src: Input 8-bit 3-channel image.
+
+    :param dst: Output image with the same size and type as  ``src``.
+
+
+**NOTE:**
+
+The algorithm assumes that the color of the source image is close to that of the destination. This assumption means that when the colors don't match, the source image color gets tinted toward the color of the destination image.

+* Author:

+*
+* This tutorial demonstrates how to use OpenCV seamless cloning
+* module.
+* Flags:
+* 1- NORMAL_CLONE
+* 2- MIXED_CLONE
+* 3- FEATURE_EXCHANGE
+
+* The program takes as input a source and a destination image
+* and ouputs the cloned image.
+
+* Step 1:
+* -> In the source image, select the region of interest by left click mouse button. A Polygon ROI will be created by left clicking mouse button.
+* -> To set the Polygon ROI, click the right mouse button.
+* -> To reset the region selected, click the middle mouse button.
+
+* Step 2:
+* -> In the destination image, select the point where you want to place the ROI in the image by left clicking mouse button.
+* -> To get the cloned result, click the right mouse button.
+
+* Result: The cloned image will be displayed.
