## 快速开始
### 数据准备
我们使用[WIDER-FACE数据集](http://shuoyang1213.me/WIDERFACE/)进行训练和模型测试，官方网站提供了详细的数据介绍。
- WIDER-Face数据源:
使用如下目录结构加载`wider_face`类型的数据集：
```
dataset/wider_face/
├── wider_face_split
│ ├── wider_face_train_bbx_gt.txt
│ ├── wider_face_val_bbx_gt.txt
├── WIDER_train
│ ├── images
│ │ ├── 0--Parade
│ │ │ ├── 0_Parade_marchingband_1_100.jpg
│ │ │ ├── 0_Parade_marchingband_1_381.jpg
│ │ │ │ ...
│ │ ├── 10--People_Marching
│ │ │ ...
├── WIDER_val

│ │ │ ├── 0_Parade_marchingband_1_1045.jpg
│ │ │ │ ...
│ │ ├── 10--People_Marching
│ │ │ ...
```
- 手动下载数据集：
要下载WIDER-FACE数据集，请运行以下命令：
```
cd dataset/wider_face && ./download.sh
```
- 自动下载数据集：
如果已经开始训练，但是数据集路径设置不正确或找不到路径, PaddleDetection会从[WIDER-FACE数据集](http://shuoyang1213.me/WIDERFACE/)自动下载它们，
下载后解压的数据集将缓存在`~/.cache/paddle/dataset/`中，并且之后的训练测试会自动加载它们。
#### 数据增强方法
- **尺度变换(Data-anchor-sampling):**
具体操作是:根据随机选择的人脸高和宽，获取到$v=\sqrt{width * height}$，之后再判断`v`的值范围，其中`v`值位于缩放区间`[16,32,64,128]`
假设`v=45`，则选定`32<v<64`, 以均匀分布的概率选取`[16,32,64]`中的任意一个值。若选中`64`，则该人脸的缩放区间在`[64 / 2, min(v * 2, 64 * 2)]`中选定。
- **其他方法:** 包括随机扰动、翻转、裁剪等。具体请参考[DATA_cn.md](../../docs/DATA_cn.md#APIs)。
### 训练与推理
训练流程与推理流程方法与其他算法一致，请参考[GETTING_STARTED_cn.md](../../docs/GETTING_STARTED_cn.md)。
**注意:**
- `BlazeFace`和`FaceBoxes`训练是以每卡`batch_size=8`在4卡GPU上进行训练(总`batch_size`是32),并且训练320000轮
(如果你的GPU数达不到4，请参考[学习率计算规则表](../../docs/GETTING_STARTED_cn.md#faq))。
- 人脸检测模型目前我们不支持边训练边评估。
### 评估
目前我们支持在`WIDER FACE`数据集和`FDDB`数据集上评估。首先运行`tools/face_eval.py`生成评估结果文件，其次使用matlab（WIDER FACE）
或OpenCV（FDDB）计算具体的评估指标。
其中，运行`tools/face_eval.py`的参数列表如下：
- `-f` 或者 `--output_eval`: 评估生成的结果文件保存路径，默认是： `output/pred`；
- `-e` 或者 `--eval_mode`: 评估模式，包括 `widerface` 和 `fddb`，默认是`widerface`；
- `--multi_scale`: 如果在命令中添加此操作按钮，它将选择多尺度评估。默认值为`False`，它将选择单尺度评估。
#### 在WIDER-FACE数据集上评估
评估并生成结果文件：
```
export CUDA_VISIBLE_DEVICES=0
export PYTHONPATH=$PYTHONPATH:.
python -u tools/face_eval.py -c configs/face_detection/blazeface.yml \
-o weights=output/blazeface/model_final/ \
--eval_mode=widerface
```
评估完成后，将在`output/pred`中生成txt格式的测试结果。
- 下载官方评估脚本来评估AP指标：
```
wget http://mmlab.ie.cuhk.edu.hk/projects/WIDERFace/support/eval_script/eval_tools.zip
unzip eval_tools.zip && rm -f eval_tools.zip
```
- 在`eval_tools/wider_eval.m`中修改保存结果路径和绘制曲线的名称：
```
# Modify the folder name where the result is stored.
pred_dir = './pred';
# Modify the name of the curve to be drawn
legend_name = 'Fluid-BlazeFace';
```
- `wider_eval.m` 是评估模块的主要执行程序。运行命令如下：
```
matlab -nodesktop -nosplash -nojvm -r "run wider_eval.m;quit;"
```
#### 在FDDB数据集上评估
我们提供了一套FDDB数据集的评估流程(目前仅支持Linux系统)，其他具体细节请参考[FDDB官网](http://vis-www.cs.umass.edu/fddb/)。
- 1)下载安装opencv：
下载OpenCV: 进入[OpenCV library](https://opencv.org/releases/)手动下载
安装OpenCV：请参考[OpenCV官方安装教程](https://docs.opencv.org/master/d7/d9f/tutorial_linux_install.html)通过源码安装。
- 2)下载数据集、评估代码以及格式化数据：
```
./dataset/fddb/download.sh
```
- 3)编译FDDB评估代码：
进入`dataset/fddb/evaluation`目录下，修改MakeFile文件中内容如下：
```
evaluate: $(OBJS)
$(CC) $(OBJS) -o $@ $(LIBS)
```
修改`common.hpp`中内容为如下形式：
```
#define __IMAGE_FORMAT__ ".jpg"
//#define __IMAGE_FORMAT__ ".ppm"
#define __CVLOADIMAGE_WORKING__
```
根据`grep -r "CV_RGB"`命令找到含有`CV_RGB`的代码段，将`CV_RGB`改成`Scalar`，并且在cpp中加入`using namespace cv;`，
然后编译：
```
make clean && make
```
- 4)开始评估:
修改config文件中`dataset_dir`和`annotation`字段内容：
```
EvalReader:
...
dataset:
dataset_dir: dataset/fddb
anno_path: FDDB-folds/fddb_annotFile.txt
...
```
评估并生成结果文件：
```
python -u tools/face_eval.py -c configs/face_detection/blazeface.yml \
-o weights=output/blazeface/model_final/ \
--eval_mode=fddb
```
评估完成后，将在`output/pred/pred_fddb_res.txt`中生成txt格式的测试结果。
生成ContROC与DiscROC数据：
```
cd dataset/fddb/evaluation
./evaluate -a ./FDDB-folds/fddb_annotFile.txt \
-f 0 -i ./ -l ./FDDB-folds/filePath.txt -z .jpg \
-d {RESULT_FILE} \
-r {OUTPUT_DIR}
```
**注意:**
(1)`RESULT_FILE`是`tools/face_eval.py`输出的FDDB预测结果文件；
(2)`OUTPUT_DIR`是FDDB评估输出结果文件前缀，会生成两个文件`{OUTPUT_DIR}ContROC.txt`、`{OUTPUT_DIR}DiscROC.txt`；
(3)参数用法及注释可通过执行`./evaluate --help`来获取。
## 算法细节
### BlazeFace
**简介:**
[BlazeFace](https://arxiv.org/abs/1907.05047) 是Google Research发布的人脸检测模型。它轻巧并且性能良好，
专为移动GPU推理量身定制。在旗舰设备上，速度可达到200-1000+FPS。
**特点:**
- 锚点策略在8×8（输入128x128）的特征图上停止，在该分辨率下每个像素点6个锚点；
- 5个单BlazeBlock和6个双BlazeBlock：5×5 depthwise卷积，可以保证在相同精度下网络层数更少；
- 用混合策略替换非极大值抑制算法，该策略将边界框的回归参数估计为重叠预测之间的加权平均值。
**版本信息:**
- 原始版本: 参考原始论文复现；
- Lite版本: 使用3x3卷积替换5x5卷积，更少的网络层数和通道数；

# Data Pipline
## Introduction
The data pipeline is responsible for loading and converting data. Each
resulting data sample is a tuple of np.ndarrays.
For example, Faster R-CNN training uses samples of this format: `[(im,
im_info, im_id, gt_bbox, gt_class, is_crowd), (...)]`.
### Implementation
The data pipeline consists of four sub-systems: data parsing, image
pre-processing, data conversion and data feeding APIs.
Data samples are collected to form `data.Dataset`s, usually 3 sets are
needed for training, validation, and testing respectively.
First, `data.source` loads the data files into memory, then
`data.transform` processes them, and lastly, the batched samples
are fetched by `data.Reader`.
Sub-systems details:
1. Data parsing
Parses various data sources and creates `data.Dataset` instances. Currently,
following data sources are supported:
- COCO data source
Loads `COCO` type datasets with directory structures like this:
```
dataset/coco/
├── annotations
│ ├── instances_train2014.json
│ ├── instances_train2017.json
│ ├── instances_val2014.json
│ ├── instances_val2017.json
│ | ...
├── train2017
│ ├── 000000000009.jpg
│ ├── 000000580008.jpg
│ | ...
├── val2017
│ ├── 000000000139.jpg
│ ├── 000000000285.jpg
│ | ...
| ...
```
- Pascal VOC data source
Loads `Pascal VOC` like datasets with directory structure like this:
```
dataset/voc/
├── train.txt
├── val.txt
├── test.txt
├── label_list.txt (optional)
├── VOCdevkit/VOC2007
│ ├── Annotations
│ ├── 001789.xml
│ | ...
│ ├── JPEGImages
│ ├── 001789.xml
│ | ...
│ ├── ImageSets
│ | ...
├── VOCdevkit/VOC2012
│ ├── Annotations
│ ├── 003876.xml
│ | ...
│ ├── JPEGImages
│ ├── 003876.xml
│ | ...
│ ├── ImageSets
│ | ...
| ...
```
**NOTE:** If you set `use_default_label=False` in yaml configs, the `label_list.txt`
of Pascal VOC dataset will be read, otherwise, `label_list.txt` is unnecessary and
the default Pascal VOC label list which defined in
[voc\_loader.py](../ppdet/data/source/voc_loader.py) will be used.
- Roidb data source
A generalized data source serialized as pickle files, which have the following
structure:
```python
(records, cname2id)
# `cname2id` is a `dict` which maps category name to class IDs
# and `records` is a list of dict of this structure:
{
'im_file': im_fname, # image file name
'im_id': im_id, # image ID
'h': im_h, # height of image
'w': im_w, # width of image
'is_crowd': is_crowd, # crowd marker
'gt_class': gt_class, # ground truth class
'gt_bbox': gt_bbox, # ground truth bounding box
'gt_poly': gt_poly, # ground truth segmentation
}
```
We provide a tool to generate roidb data sources. To convert `COCO` or `VOC`
like dataset, run this command:
```sh
# --type: the type of original data (xml or json)
# --annotation: the path of file, which contains the name of annotation files
# --save-dir: the save path
# --samples: the number of samples (default is -1, which mean all datas in dataset)
python ./ppdet/data/tools/generate_data_for_training.py
--type=json \
--annotation=./annotations/instances_val2017.json \
--save-dir=./roidb \
--samples=-1
```
2. Image preprocessing
the `data.transform.operator` module provides operations such as image
decoding, expanding, cropping, etc. Multiple operators are combined to form
larger processing pipelines.
3. Data transformer
Transform a `data.Dataset` to achieve various desired effects, Notably: the
`data.transform.paralle_map` transformer accelerates image processing with
multi-threads or multi-processes. More transformers can be found in
`data.transform.transformer`.
4. Data feeding apis
To facilitate data pipeline building, we combine multiple `data.Dataset` to
form a `data.Reader` which can provide data for training, validation and
testing respectively. Users can simply call `Reader.[train|eval|infer]` to get
the corresponding data stream. Many aspect of the `Reader`, such as storage
location, preprocessing pipeline, acceleration mode can be configured with yaml
files.
### APIs
The main APIs are as follows:
1. Data parsing
- `source/coco_loader.py`: COCO dataset parser. [source](../ppdet/data/source/coco_loader.py)
- `source/voc_loader.py`: Pascal VOC dataset parser. [source](../ppdet/data/source/voc_loader.py)
[Note] To use a non-default label list for VOC datasets, a `label_list.txt`
file is needed, one can use the provided label list
(`data/pascalvoc/ImageSets/Main/label_list.txt`) or generate a custom one (with `tools/generate_data_for_training.py`). Also, `use_default_label` option should
be set to `false` in the configuration file
- `source/loader.py`: Roidb dataset parser. [source](../ppdet/data/source/loader.py)
2. Operator
`transform/operators.py`: Contains a variety of data augmentation methods, including:
- `DecodeImage`: Read images in RGB format.
- `RandomFlipImage`: Horizontal flip.
- `RandomDistort`: Distort brightness, contrast, saturation, and hue.
- `ResizeImage`: Resize image with interpolation.
- `RandomInterpImage`: Use a random interpolation method to resize the image.
- `CropImage`: Crop image with respect to different scale, aspect ratio, and overlap.
- `ExpandImage`: Pad image to a larger size, padding filled with mean image value.
- `NormalizeImage`: Normalize image pixel values.
- `NormalizeBox`: Normalize the bounding box.
- `Permute`: Arrange the channels of the image and optionally convert image to BGR format.
- `MixupImage`: Mixup two images with given fraction<sup>[1](#mix)</sup>.
<a name="mix">[1]</a> Please refer to [this paper](https://arxiv.org/pdf/1710.09412.pdf)。
`transform/arrange_sample.py`: Assemble the data samples needed by different models.
3. Transformer
`transform/post_map.py`: Transformations that operates on whole batches, mainly for:
- Padding whole batch to given stride values
- Resize images to Multi-scales
- Randomly adjust the image size of the batch data
`transform/transformer.py`: Data filtering batching.
`transform/parallel_map.py`: Accelerate data processing with multi-threads/multi-processes.
4. Reader
`reader.py`: Combine source and transforms, return batch data according to `max_iter`.
`data_feed.py`: Configure default parameters for `reader.py`.
### Usage
#### Canned Datasets
Preset for common datasets, e.g., `COCO` and `Pascal Voc` are included. In
most cases, user can simply use these canned dataset as is. Moreover, the
whole data pipeline is fully customizable through the yaml configuration files.
#### Custom Datasets
- Option 1: Convert the dataset to COCO format.
```sh
# a small utility (`tools/x2coco.py`) is provided to convert
# Labelme-annotated dataset or cityscape dataset to COCO format.
python ./ppdet/data/tools/x2coco.py --dataset_type labelme
--json_input_dir ./labelme_annos/
--image_input_dir ./labelme_imgs/
--output_dir ./cocome/
--train_proportion 0.8
--val_proportion 0.2
--test_proportion 0.0
# --dataset_type: The data format which is need to be converted. Currently supported are: 'labelme' and 'cityscape'
# --json_input_dir：The path of json files which are annotated by Labelme.
# --image_input_dir：The path of images.
# --output_dir：The path of coverted COCO dataset.
# --train_proportion：The train proportion of annatation data.
# --val_proportion：The validation proportion of annatation data.
# --test_proportion: The inference proportion of annatation data.
```
- Option 2:
1. Add `source/XX_loader.py` and implement the `load` function, following the
example of `source/coco_loader.py` and `source/voc_loader.py`.
2. Modify the `load` function in `source/loader.py` to make use of the newly
added data loader.
3. Modify `/source/__init__.py` accordingly.
```python
if data_cf['type'] in ['VOCSource', 'COCOSource', 'RoiDbSource']:
source_type = 'RoiDbSource'
# Replace the above code with the following code:
if data_cf['type'] in ['VOCSource', 'COCOSource', 'RoiDbSource', 'XXSource']:
source_type = 'RoiDbSource'
```
4. In the configure file, define the `type` of `dataset` as `XXSource`.
#### How to add data pre-processing？
- To add pre-processing operation for a single image, refer to the classes in
`transform/operators.py`, and implement the desired transformation with a new
class.
- To add pre-processing for a batch, one needs to modify the `build_post_map`
function in `transform/post_map.py`.

# 数据模块
## 介绍
本模块是一个Python模块，用于加载数据并将其转换成适用于检测模型的训练、验证、测试所需要的格式——由多个np.ndarray组成的tuple数组，例如用于Faster R-CNN模型的训练数据格式为：`[(im, im_info, im_id, gt_bbox, gt_class, is_crowd), (...)]`。
### 实现
该模块内部可分为4个子功能：数据解析、图片预处理、数据转换和数据获取接口。
我们采用`data.Dataset`表示一份数据，比如`COCO`数据包含3份数据，分别用于训练、验证和测试。原始数据存储与文件中，通过`data.source`加载到内存，然后使用`data.transform`对数据进行处理转换，最终通过`data.Reader`的接口可以获得用于训练、验证和测试的batch数据。
子功能介绍：
1. 数据解析
数据解析得到的是`data.Dataset`,实现逻辑位于`data.source`中。通过它可以实现解析不同格式的数据集，已支持的数据源包括：
- COCO数据源
该数据集目前分为COCO2014和COCO2017，主要由json文件和image文件组成，其组织结构如下所示：
```
dataset/coco/
├── annotations
│ ├── instances_train2014.json
│ ├── instances_train2017.json
│ ├── instances_val2014.json
│ ├── instances_val2017.json
│ | ...
├── train2017
│ ├── 000000000009.jpg
│ ├── 000000580008.jpg
│ | ...
├── val2017
│ ├── 000000000139.jpg
│ ├── 000000000285.jpg
│ | ...
| ...
```
- Pascal VOC数据源
该数据集目前分为VOC2007和VOC2012，主要由xml文件和image文件组成，其组织结构如下所示：
```
dataset/voc/
├── train.txt
├── val.txt
├── test.txt
├── label_list.txt (optional)
├── VOCdevkit/VOC2007
│ ├── Annotations
│ ├── 001789.xml
│ | ...
│ ├── JPEGImages
│ ├── 001789.xml
│ | ...
│ ├── ImageSets
│ | ...
├── VOCdevkit/VOC2012
│ ├── Annotations
│ ├── 003876.xml
│ | ...
│ ├── JPEGImages
│ ├── 003876.xml
│ | ...
│ ├── ImageSets
│ | ...
| ...
```
**说明：** 如果你在yaml配置文件中设置`use_default_label=False`, 将从`label_list.txt`
中读取类别列表，反之则可以没有`label_list.txt`文件，检测库会使用Pascal VOC数据集的默
认类别列表，默认类别列表定义在[voc\_loader.py](../ppdet/data/source/voc_loader.py)
- Roidb数据源
该数据集主要由COCO数据集和Pascal VOC数据集转换而成的pickle文件，包含一个dict，而dict中只包含一个命名为‘records’的list（可能还有一个命名为‘cname2cid’的字典），其内容如下所示：
```python
(records, catname2clsid)
'records'是一个list并且它的结构如下:
{
'im_file': im_fname, # 图像文件名
'im_id': im_id, # 图像id
'h': im_h, # 图像高度
'w': im_w, # 图像宽度
'is_crowd': is_crowd, # 是否重叠
'gt_class': gt_class, # 真实框类别
'gt_bbox': gt_bbox, # 真实框坐标
'gt_poly': gt_poly, # 多边形坐标
}
'cname2id'是一个dict，保存了类别名到id的映射
```
我们在`./tools/`中提供了一个生成roidb数据集的代码，可以通过下面命令实现该功能。
```
# --type: 原始数据集的类别（只能是xml或者json）
# --annotation: 一个包含所需标注文件名的文件的路径
# --save-dir: 保存路径
# --samples: sample的个数（默认是-1，代表使用所有sample）
python ./ppdet/data/tools/generate_data_for_training.py
--type=json \
--annotation=./annotations/instances_val2017.json \
--save-dir=./roidb \
--samples=-1
```
2. 图片预处理
图片预处理通过包括图片解码、缩放、裁剪等操作，我们采用`data.transform.operator`算子的方式来统一实现，这样能方便扩展。此外，多个算子还可以组合形成复杂的处理流程, 并被`data.transformer`中的转换器使用，比如多线程完成一个复杂的预处理流程。
3. 数据转换器
数据转换器的功能是完成对某个`data.Dataset`进行转换处理，从而得到一个新的`data.Dataset`。我们采用装饰器模式实现各种不同的`data.transform.transformer`。比如用于多进程预处理的`dataset.transform.paralle_map`转换器。
4. 数据获取接口
为方便训练时的数据获取，我们将多个`data.Dataset`组合在一起构成一个`data.Reader`为用户提供数据，用户只需要调用`Reader.[train|eval|infer]`即可获得对应的数据流。`Reader`支持yaml文件配置数据地址、预处理过程、加速方式等。
### APIs

- `source/voc_loader.py`：用于解析Pascal VOC数据集。[详见代码](../ppdet/data/source/voc_loader.py)
[注意]在使用VOC数据集时，若不使用默认的label列表，则需要先使用`tools/generate_data_for_training.py`生成`label_list.txt`（使用方式与数据解析中的roidb数据集获取过程一致），或提供`label_list.txt`放置于`data/pascalvoc/ImageSets/Main`中；同时在配置文件中设置参数`use_default_label`为`true`。
- `source/loader.py`：用于解析Roidb数据集。[详见代码](../ppdet/data/source/loader.py)
2. 算子
`transform/operators.py`：包含多种数据增强方式，主要包括：

ResizeImage：根据特定的插值方式调整图像大小。
RandomInterpImage：使用随机的插值方式调整图像大小。
CropImage：根据缩放比例、长宽比例两个参数生成若干候选框，再依据这些候选框和标注框的面积交并比(IoU)挑选出符合要求的裁剪结果。
ExpandImage：将原始图片放进一张使用像素均值填充(随后会在减均值操作中减掉)的扩张图中，再对此图进行裁剪、缩放和翻转。
DecodeImage：以RGB格式读取图像。
Permute：对图像的通道进行排列并转为BGR格式。
NormalizeImage：对图像像素值进行归一化。
NormalizeBox：对bounding box进行归一化。

```
[注意]：Mixup的操作可参考[论文](https://arxiv.org/pdf/1710.09412.pdf)。
`transform/arrange_sample.py`：实现对输入网络数据的排序。
3. 转换
`transform/post_map.py`：用于完成批数据的预处理操作，其主要包括：
``` python
随机调整批数据的图像大小
多尺度调整图像大小
padding操作
```
`transform/transformer.py`：用于过滤无用的数据，并返回批数据。
`transform/parallel_map.py`：用于实现加速。
4. 读取
`reader.py`：用于组合source和transformer操作，根据`max_iter`返回batch数据。
`data_feed.py`: 用于配置 `reader.py`中所需的默认参数.
### 使用
#### 常规使用
结合yaml文件中的配置信息，完成本模块的功能。yaml文件的使用可以参见配置文件部分。
- 读取用于训练的数据
``` python
ccfg = load_cfg('./config.yml')
coco = Reader(ccfg.DATA, ccfg.TRANSFORM, maxiter=-1)
```
#### 如何使用自定义数据集？
- 选择1：将数据集转换为COCO格式。
```
# 在./tools/中提供了x2coco.py用于将labelme标注的数据集或cityscape数据集转换为COCO数据集
python ./ppdet/data/tools/x2coco.py --dataset_type labelme
--json_input_dir ./labelme_annos/
--image_input_dir ./labelme_imgs/
--output_dir ./cocome/
--train_proportion 0.8

--test_proportion 0.0
# --dataset_type：需要转换的数据格式，目前支持：’labelme‘和’cityscape‘
# --json_input_dir：使用labelme标注的json文件所在文件夹
# --image_input_dir：图像文件所在文件夹
# --output_dir：转换后的COCO格式数据集存放位置
# --train_proportion：标注数据中用于train的比例
# --val_proportion：标注数据中用于validation的比例
# --test_proportion: 标注数据中用于infer的比例
```
- 选择2：
1. 仿照`./source/coco_loader.py`和`./source/voc_loader.py`，添加`./source/XX_loader.py`并实现`load`函数。
2. 在`./source/loader.py`的`load`函数中添加使用`./source/XX_loader.py`的入口。
3. 修改`./source/__init__.py`：
```python
if data_cf['type'] in ['VOCSource', 'COCOSource', 'RoiDbSource']:
source_type = 'RoiDbSource'
# 将上述代码替换为如下代码：
if data_cf['type'] in ['VOCSource', 'COCOSource', 'RoiDbSource', 'XXSource']:
source_type = 'RoiDbSource'
```
4. 在配置文件中修改`dataset`下的`type`为`XXSource`。
#### 如何增加数据预处理？
- 若增加单张图像的增强预处理，可在`transform/operators.py`中参考每个类的代码，新建一个类来实现新的数据增强；同时在配置文件中增加该预处理。
- 若增加单个batch的图像预处理，可在`transform/post_map.py`中参考`build_post_map`中每个函数的代码，新建一个内部函数来实现新的批数据预处理；同时在配置文件中增加该预处理。

## 新增模型
我们以单阶段检测器YOLOv3为例，结合[yolov3_darknet.yml](https://github.com/PaddlePaddle/PaddleDetection/blob/master/configs/yolov3_darknet.yml)配置文件，对建立模型过程进行详细描述，
按照此思路您可以快速搭建新的模型。
搭建新模型的一般步骤是：Backbone编写、检测组件编写与模型组网这三个步骤，下面为您详细介绍：
### Backbone编写
1.代码编写：
PaddleDetection中现有所有Backbone网络代码都放置在`ppdet/modeling/backbones`目录下，所以我们在其中新建`darknet.py`如下：
```python
from ppdet.core.workspace import register
@register
class DarkNet(object):
__shared__ = ['norm_type', 'weight_prefix_name']
def __init__(self,
depth=53,
norm_type='bn',
norm_decay=0.,
weight_prefix_name=''):
# 省略内容
pass
def __call__(self, input):
# 省略处理逻辑
pass
```
然后在`backbones/__init__.py`中加入引用：
```python
from . import darknet
from .darknet import *
```
**几点说明：**
- 为了在yaml配置文件中灵活配置网络，所有Backbone、模型组件与architecture类需要利用`ppdet.core.workspace`里的`register`进行注册，形式请参考如上示例；
- 在Backbone中都需定义`__init__`函数与`__call__`函数，`__init__`函数负责初始化参数，在调用此Backbone时会执行`__call__`函数；
- `__shared__`为了实现一些参数的配置全局共享，具体细节请参考[配置文件说明文档](CONFIG_cn.md#faq)。
2.配置编写：
在yaml文件中以注册好了的`DarkNet`类名为标题，可选择性的对`__init__`函数中的参数进行更新，不在配置文件中配置的参数会保持`__init__`函数中的初始化值：
```yaml
DarkNet:
norm_type: sync_bn
norm_decay: 0.
depth: 53
```
### 检测组件编写
1.代码编写：编写好Backbone后，我们开始编写生成anchor的检测头部分，anchor的检测头代码都在`ppdet/modeling/anchor_heads`目录下，所以我们在其中新建`yolo_head.py`如下：
```python
from ppdet.core.workspace import register
@register
class YOLOv3Head(object):
__inject__ = ['yolo_loss', 'nms']
__shared__ = ['num_classes', 'weight_prefix_name']
def __init__(self,
num_classes=80,
anchors=[[10, 13], [16, 30], [33, 23], [30, 61], [62, 45],
[59, 119], [116, 90], [156, 198], [373, 326]],
yolo_loss="YOLOv3Loss",
nms=MultiClassNMS(
score_threshold=0.01,
nms_top_k=1000,
keep_top_k=100,
nms_threshold=0.45,
background_label=-1).__dict__):
# 省略部分内容
pass
```
然后在`anchor_heads/__init__.py`中加入引用：
```python
from . import yolo_head
from .yolo_head import *
```
**几点说明：**
- `__inject__`表示引入封装好了的检测组件/算子列表，此处`yolo_loss`与`nms`变量指向外部定义好的检测组件/算子；
- anchor的检测头实现中类函数需有输出loss接口`get_loss`与预测框或建议框输出接口`get_prediction`；
- 两阶段检测器在anchor的检测头里定义的是候选框输出接口`get_proposals`，之后还会在`roi_extractors`与`roi_heads`中进行后续计算，定义方法与如下一致。
- YOLOv3算法的loss函数比较复杂，所以我们将loss函数进行拆分，具体实现在`losses/yolo_loss.py`中，也需要注册；
- nms算法是封装paddlepaddle中现有检测组件/算子，如何定义与注册详见[定义公共检测组件/算子](#定义公共检测组件/算子)部分。
2.配置编写：
在yaml文件中以注册好了的`YOLOv3Head`类名为标题，可选择性的对`__init__`函数中的参数进行更新，不在配置文件中配置的参数会保持`__init__`函数中的初始化值：
```yaml
YOLOv3Head:
anchor_masks: [[6, 7, 8], [3, 4, 5], [0, 1, 2]]
anchors: [[10, 13], [16, 30], [33, 23],
[30, 61], [62, 45], [59, 119],
[116, 90], [156, 198], [373, 326]]
norm_decay: 0.
yolo_loss: YOLOv3Loss
nms:
background_label: -1
keep_top_k: 100
nms_threshold: 0.45
nms_top_k: 1000
normalized: false
score_threshold: 0.01
YOLOv3Loss:
batch_size: 8
ignore_thresh: 0.7
label_smooth: false
```
如上配置文件中的`YOLOv3Loss`是注册好检测组件接口，所以需要在配置文件中也对`YOLOv3Loss`进行参数设置。
### 模型组网
本步骤中，我们需要将编写好的Backbone、各个检测组件进行整合拼接，搭建一个完整的物体检测网络能够提供给训练、评估和测试程序去运行。
1.组建`architecture`：
所有architecture网络代码都放置在`ppdet/modeling/architectures`目录下，所以我们在其中新建`yolov3.py`如下：
```python
from ppdet.core.workspace import register
@register
class YOLOv3(object):
__category__ = 'architecture'
__inject__ = ['backbone', 'yolo_head']
__shared__ = ['use_fine_grained_loss']
def __init__(self,
backbone,
yolo_head='YOLOv3Head',
use_fine_grained_loss=False):
super(YOLOv3, self).__init__()
# 省略内容
def build(self, feed_vars, mode='train'):
# 省略内容
pass
def build_inputs(self, ):
# 详解见【模型输入设置】章节
pass
def train(self, feed_vars):
return self.build(feed_vars, mode='train')
def eval(self, feed_vars):
return self.build(feed_vars, mode='test')
def test(self, feed_vars):
return self.build(feed_vars, mode='test')
```
**几点说明：**
- 在组建一个完整的网络时必须要设定`__category__ = 'architecture'`来表示一个完整的物体检测模型；
- 在`__init__`函数中传入我们上面定义好的`backbone`与`yolo_head`的名称即可，根据yaml配置文件里这些组件的参数初始化，`ppdet.core.workspace`会自动解析加载；
- 在architecture类里必须定义`build_inputs`函数，为了适配检测网络的输入与Reader模块，具体见[模型输入设置](#模型输入设置)模块；
- 在architecture类里必须定义`train`、`eval`和`test`函数，在训练、评估和测试程序中会分别调用这三个函数来在不同场景中加载网络模型。
2.配置编写：
首先定义网络模型名称：
```yaml
architecture: YOLOv3
```
接下来根据网络模型名称`YOLOv3`来初始化网络组件名称：
```yaml
YOLOv3:
backbone: DarkNet
yolo_head: YOLOv3Head
```
之后`backbone`、`yolo_head`的配置步骤在上面已经介绍，完成如上配置就完成了物体检测模型组网的工作。
### 模型输入设置
在architecture定义的类里必须含有`build_inputs`函数，这个函数的作用是生成`feed_vars`和`loader`。
1.`feed_vars`是由`key：fluid.data`构成的字典，key是由如下yaml文件中`fields`字段构成，在不同数据集、训练、评估和测试中字段不尽相同，
在使用中需要合理组合。
```yaml
TrainReader:
inputs_def:
fields: ['image', 'gt_bbox', 'gt_class', 'gt_score']
EvalReader:
inputs_def:
fields: ['image', 'im_size', 'im_id']
...
```
在[数据源解析](READER.md#数据解析)中已经提到，数据源roidbs会解析为字典的形式，Reader会根据feed_vars所含字段进行解析适配。
2.`loader`是调用[fluid.io.DataLoader](https://www.paddlepaddle.org.cn/documentation/docs/zh/develop/api_cn/io_cn/DataLoader_cn.html#dataloader)
根据`feed_vars`来完成DataLoader的组建。
## 定义公共检测组件/算子
为了更好的复用一些公共检测组件/算子，以及可以在yaml配置文件中配置化，检测模型相关检测组件/算子都在`ppdet/modeling/ops.py`中定义并注册。这部分是选做部分，不是必需的。
（1）基于现有的PaddlePaddle物体检测相关OP进行二次封装注册：
例如[fluid.layers.multiclass_nms](https://www.paddlepaddle.org.cn/documentation/docs/zh/develop/api_cn/layers_cn/multiclass_nms_cn.html)
在PaddlePaddle已经存在，我们想让它在yaml文件中灵活配置，我们只需要在`ops.py`中如下配置即可：
```python
from ppdet.core.workspace import register, serializable
@register
@serializable
class MultiClassNMS(object):
__op__ = fluid.layers.multiclass_nms
__append_doc__ = True
def __init__(self,
score_threshold=.05,
nms_top_k=-1,
keep_top_k=100,
nms_threshold=.5,
normalized=False,
nms_eta=1.0,
background_label=0):
super(MultiClassNMS, self).__init__()
# 省略
```
**注意：** 我们是对`fluid.layers.multiclass_nms`这个OP进行二次封装，在`__init__`方法中添加所需的可选参数即可，保持默认的参数可以不添加进来。
（2）从零开始定义检测组件/算子：
在`ops.py`中定义`xxx`函数，然后在相应位置添加`from ppdet.modeling.ops import xxx`即可调用，无需注册与序列化。
## 配置及运行
PaddleDetection在`ppdet/optimizer.py`中注册实现了学习率配置接口类`LearningRate`、优化器接口类`OptimizerBuilder`。
- 学习率配置
在yaml文件中可便捷配置学习率各个参数：
```yaml
LearningRate:
base_lr: 0.001
schedulers:
- !PiecewiseDecay
gamma: 0.1
milestones:
- 400000
- 450000
- !LinearWarmup
start_factor: 0.
steps: 4000
```
**几点说明：**
- `PiecewiseDecay`与`LinearWarmup`策略在`ppdet/optimizer.py`中都已注册。
- 除了这两个优化器之外，您还可以使用paddlepaddle中所有的优化器[paddlepaddle官网文档](https://www.paddlepaddle.org.cn/documentation/docs/zh/develop/api_guides/low_level/optimizer.html)。
- Optimizer优化器配置：
```yaml
OptimizerBuilder:
optimizer:
momentum: 0.9
type: Momentum
regularizer:
factor: 0.0005
type: L2
```
- 其他配置：在训练、评估与测试阶段，定义了一些所需参数如下：
```yaml
use_gpu: true # 是否使用GPU运行程序
max_iters: 500200 # 最大迭代轮数
log_smooth_window: 20 # 日志打印队列长度
log_iter: 20 # 训练时日志每迭代x轮打印一次
save_dir: output # 模型保存路径
snapshot_iter: 2000 # 训练时第x轮保存/评估
metric: COCO # 数据集名称
pretrain_weights: xxx # 预训练模型地址（网址/路径）
weights: xxx/model_final # 评估或测试时模型权重的路径
num_classes: 80 # 类别数
```
> 看过此文档，您应该对PaddleDetection中模型搭建与配置有了一定经验，结合源码会理解的更加透彻。关于模型技术，如您有其他问题或建议，请给我们提issue，我们非常欢迎您的反馈。

![](../images/reader_figure.png)
## 数据准备
PaddleDetection目前支持[COCO](http://cocodataset.org)、[Pascal VOC](http://host.robots.ox.ac.uk/pascal/VOC/)
和[WIDER-FACE](http://shuoyang1213.me/WIDERFACE/)数据源，默认数据集可自动下载，请参考[默认数据集安装方法](../tutorials/INSTALL_cn.md)。
同时我们还支持自定义数据源，包括(1)自定义数据源转换成COCO数据集；(2)定义新的数据源。
数据准备分为三步：
- （1）[数据解析](#数据解析)
- （2）[数据预处理](#数据预处理)
- （3）[组建Reader迭代器](#组建Reader迭代器)
下面为您分别介绍下这三步的具体内容：
### 数据解析
数据解析逻辑在`source`目录中，其中，`dataset.py`是数据源定义的基类，所有数据集继承于此，`DataSet`基类里定义了如下等方法：
| 方法 | 输入 | 输出 | 备注 |
| :------------------------: | :----: | :------------: | :--------------: |
| load_roidb_and_cname2cid() | 无 | 无 |加载`DataSet`中Roidb数据源list, 类别名到id的映射dict |
| get_roidb() | 无 | list[dict], Roidb数据源 | 获取数据源 |
| get_cname2cid() | 无 | dict，类别名到id的映射 | 获取标签ID |
| get_anno() | 无 | str, 标注文件路径 | 获取标注文件路径 |
| get_imid2path() | 无 | dict, 图片路径 | 获取图片路径 |
**几点解释：**
- `load_roidb_and_cname2cid()`在Dataset基类中并没有做实际的操作，需要在子类中重写实际操作。
- `roidbs`:
代表数据源列表。`load_roidb_and_cname2cid`方法中根据数据集标注文件(anno_path)，将每张标注好的图片解析为字典`coco_rec`和`voc_rec`等：
```python
xxx_rec = {
'im_file': im_fname, # 一张图像的完整路径
'im_id': np.array([img_id]), # 一张图像的ID序号
'h': im_h, # 图像高度
'w': im_w, # 图像宽度
'is_crowd': is_crowd, # 是否是群落对象, 默认为0 (VOC中无此字段，为了使个别模型同时适配于COCO与VOC)
'gt_class': gt_class, # 标注框标签名称的ID序号
'gt_bbox': gt_bbox, # 标注框坐标(xmin, ymin, xmax, ymax)
'gt_score': gt_score, # 标注框置信度得分 (此字段为了适配Mixup操作)
'gt_poly': gt_poly, # 分割掩码，此字段只在coco_rec中出现，默认为None
'difficult': difficult # 是否是困难样本，此字段只在voc_rec中出现，默认为0
}
```
然后将所有`xxx_rec`字典封装到`records`列表中，最后传入`self.roidbs`中方便后续调用。
- `cname2cid`:
保存了类别名到id的映射的一个dict。
- COCO数据集中：会根据[COCO API](https://github.com/cocodataset/cocoapi)自动加载cname2cid。
- VOC数据集中：如果在yaml配置文件中设置`use_default_label=False`，将从`label_list.txt`中读取类别列表，
反之则可以没有`label_list.txt`文件，PaddleDetection会使用`source/voc.py`里的默认类别字典。
`label_list.txt`的格式如下所示，每一行文本表示一个类别：
```bash
aeroplane
bicycle
bird
...
```
#### COCO数据源
该数据集目前分为COCO2014和COCO2017，主要由json文件和image文件组成，其组织结构如下所示：
```
dataset/coco/
├── annotations
│ ├── instances_train2014.json
│ ├── instances_train2017.json
│ ├── instances_val2014.json
│ ├── instances_val2017.json
│ │ ...
├── train2017
│ ├── 000000000009.jpg
│ ├── 000000580008.jpg
│ │ ...
├── val2017
│ ├── 000000000139.jpg
│ ├── 000000000285.jpg
│ │ ...
```
在`source/coco.py`中定义并注册了`COCODataSet`数据源类，它继承自`DataSet`基类，并重写了`load_roidb_and_cname2cid`：
根据标注文件路径（anno_path），调用[COCO API](https://github.com/cocodataset/cocoapi)加载并解析COCO格式数据源`roidbs`和`cname2cid`。
#### Pascal VOC数据源
该数据集目前分为VOC2007和VOC2012，主要由xml文件和image文件组成，其组织结构如下所示：
```
dataset/voc/
├── train.txt
├── val.txt
├── test.txt
├── label_list.txt (optional)
├── VOCdevkit/VOC2007
│ ├── Annotations
│ ├── 001789.xml
│ │ ...
│ ├── JPEGImages
│ ├── 001789.xml
│ │ ...
│ ├── ImageSets
│ | ...
├── VOCdevkit/VOC2012
│ ├── Annotations
│ ├── 003876.xml
│ │ ...
│ ├── JPEGImages
│ ├── 003876.xml
│ │ ...
│ ├── ImageSets
│ │ ...
```
在`source/voc.py`中定义并注册了`VOCDataSet`数据源类，它继承自`DataSet`基类，并重写了`load_roidb_and_cname2cid`，解析VOC数据集中xml格式标注文件，更新`roidbs`和`cname2cid`。
#### 自定义数据源
##### 方式一：将数据集转换为COCO格式
在`./tools/`中提供了`x2coco.py`用于将labelme标注的数据集或cityscape数据集转换为COCO数据集:
```bash
python ./ppdet/data/tools/x2coco.py \
--dataset_type labelme \
--json_input_dir ./labelme_annos/ \
--image_input_dir ./labelme_imgs/ \
--output_dir ./cocome/ \
--train_proportion 0.8 \
--val_proportion 0.2 \
--test_proportion 0.0 \
```
**参数说明：**
- `--dataset_type`：需要转换的数据格式，目前支持：’labelme‘和’cityscape‘
- `--json_input_dir`：使用labelme标注的json文件所在文件夹
- `--image_input_dir`：图像文件所在文件夹
- `--output_dir`：转换后的COCO格式数据集存放位置
- `--train_proportion`：标注数据中用于train的比例
- `--val_proportion`：标注数据中用于validation的比例
- `--test_proportion`：标注数据中用于infer的比例
##### 方式二：添加新数据源
- （1）新建`./source/xxx.py`，定义类`XXXDataSet`继承自`DataSet`基类，完成注册与序列化，并重写`load_roidb_and_cname2cid`方法对`roidbs`与`cname2cid`更新：
```python
@register
@serializable
class XXXDataSet(DataSet):
def __init__(self,
dataset_dir=None,
image_dir=None,
anno_path=None,
...
):
self.roidbs = None
self.cname2cid = None
...
def load_roidb_and_cname2cid(self):
...
省略具体解析数据逻辑
...
self.roidbs, self.cname2cid = records, cname2cid
```
- （2）在`source/__init__.py`中添加引用：
```python
from . import xxx
from .xxx import *
```
完成以上两步就将新的数据源`XXXDataSet`添加好了，操作非常简单。
### 数据预处理
#### 数据增强算子
PaddleDetection中支持了种类丰富的数据增强算子，有单图像数据增强算子与批数据增强算子两种方式，您可选取合适的算子组合使用，已支持的单图像数据增强算子详见下表：
| 名称 | 作用 |
| :---------------------: | :--------------: |
| DecodeImage | 从图像文件或内存buffer中加载图像，格式为BGR、HWC格式，如果设置to_rgb=True，则转换为RGB格式。|
| ResizeImage | 根据特定的插值方式调整图像大小 |
| RandomFlipImage | 随机水平翻转图像 |
| NormalizeImage | 对图像像素值进行归一化，如果设置is_scale=True，则先将像素值除以255.0，像素值缩放到到[0-1]区间。 |
| RandomDistort | 随机扰动图片亮度、对比度、饱和度和色相 |
| ExpandImage | 将原始图片放入用像素均值填充(随后会在减均值操作中减掉)的扩张图中，对此图进行裁剪、缩放和翻转 |
| CropImage | 根据缩放比例、长宽比例生成若干候选框，再依据这些候选框和标注框的面积交并比(IoU)挑选出符合要求的裁剪结果 |
| CropImageWithDataAchorSampling | 基于CropImage，在人脸检测中，随机将图片尺度变换到一定范围的尺度，大大增强人脸的尺度变化 |
| NormalizeBox | 对bounding box进行归一化 |
| Permute | 对图像的通道进行排列并转为BGR格式。假如输入是HWC顺序，通道C上是RGB格式，设置channel_first=True，将变成CHW，设置to_bgr=True，通道C上变成BGR格式。 |
| MixupImage | 按比例叠加两张图像 |
| RandomInterpImage | 使用随机的插值方式调整图像大小 |
| Resize | 根据特定的插值方式同时调整图像与bounding box的大小|
| MultiscaleTestResize | 将图像重新缩放为多尺度list的每个尺寸 |
| ColorDistort | 根据特定的亮度、对比度、饱和度和色相为图像增加噪声 |
| NormalizePermute | 归一化图像并改变图像通道顺序|
| RandomExpand | 原理同ExpandImage，以随机比例与角度对图像进行裁剪、缩放和翻转 |
| RandomCrop | 原理同CropImage，以随机比例与IoU阈值进行处理 |
| PadBox | 如果bounding box的数量少于num_max_boxes，则将零填充到bbox |
| BboxXYXY2XYWH | 将bounding box从(xmin,ymin,xmax,ymin)形式转换为(xmin,ymin,width,height)格式 |
**几点说明：**
- 上表中的数据增强算子的输入与输出都是单张图片`sample`，`sample`是由{'image':xx, 'im_info': xxx, ...}组成，来自于上文提到的`roidbs`中的字典信息。
- 数据增强算子注册后即可生效，在配置yaml文件中添加即可，配置文件中配置方法见下文。
- Mixup的操作可参考[论文](https://arxiv.org/pdf/1710.09412.pdf)。
批数据增强算子列表如下：
| 名称 | 输入与输出 | 作用 |
| :---------------------: | :------: | :--------------: |
| RandomShape | samples | 随机对每个batch的数据图片进行resize操作 |
| PadMultiScaleTest | samples | 在多尺度测试中对图像进行填充 |
| Gt2YoloTarget | samples | 通过gt数据生成YOLOv3目标，此OP仅在拆分后的YOLOv3损失模式下使用 |
- 批数据增强算子的输入输出都是批数据`samples`，是一个`sample`的list。
- 需要批数据增强算子的原因: CNN计算时需要一个batch内的图像大小相同，而一些数据增强算子，比如随机大小缩放，会随机选择一个缩放尺寸，为了使得一个batch内的图像大小相同，先组成batch，再做随机大小缩放的数据增强。
#### 自定义数据增强算子
假如我们定义一个新的单图像数据增强算子`XXXImage`。
- 在`transform/operators.py`中增加类`XXXImage`继承自BaseOperator，并注册：
```python
@register_op
class XXXImage(BaseOperator):
def __init__(self,...):
super(XXXImage, self).__init__()
...
def __call__(self, sample, context=None):
...
省略对输入的sample具体操作
...
return sample
```
如此就完成新增单图像数据增强算子`XXXImage`，操作非常简单。
自定义批量数据增强算子方法同上，在`transform/batch_operators.py`中定义即可。
### 组建Reader迭代器
如上面提到，Reader预处理流程为: 单张图像处理 -> 组batch -> batch图像处理。用户一般不需要关注这些方法。
在`reader.py`中构建了Reader迭代器类，其中包含如下方法：
| 方法 | 输入 | 输出 | 备注 |
| :-----------: | :----: | :-------: | :--------------: |
| reset() | 无 | 无 | 重置Reader迭代器 |
| next() | 无 | list | 返回Reader迭代器接下来输出的批数据 |
| worker() | bool,list | list | 数据预处理的接口，输入(drop_empty, batch_samples)，输出批数据list |
| size() | 无 | int | 返回roidbs的长度 |
| drained() | 无 | bool | 判断当前Reader迭代器中数据是否已经读完 |
| stop() | 无 | 无 | 停止Reader迭代器 |
Reader迭代器的创建使用`reader.py`中的`create_reader`方法，在create_reader函数中需要传入`cfg`参数列表，参数列表详细内容如下：
| 参数名 | 类型 | 含义 |
| :-----------: | :-------: | :--------------: |
| sample_transforms | list of BaseOperator | 使用各种单图像数据增强算子的列表 |
| batch_transforms | list of BaseOperator | 使用批数据数据增强算子的列表 |
| batch_size | int | 批数据大小（图像个数/batch） |
| shuffle | bool | 是否随机打乱数据集中图像排序，默认False |
| drop_last | bool | 是否删除最后一个batch的数据，默认False |
| drop_empty | bool | 是否删除空数据，默认True |
| mixup_epoch | int | 在第几个epoch使用Mixup数据增强策略，默认不使用（-1） |
| class_aware_sampling |bool | 是否使用class-aware数据增强方法，默认False |
| worker_num | int | 数据读取中使用多进程的数量 |
| use_process | bool | 数据读取中是否使用多进程 |
| bufsize | int | 多进程/多线程缓冲队列的大小，队列中每个元素为一个batch的数据 |
| memsize | str | 多进程下共享存储队列的大小，默认3G |
| inputs_def | dict | 用在网络输入定义中获取输入字段，该字段用于确定返回数据的顺序。 |
## 配置及运行
在模型的训练、评估与推理的数据处理，都是通过配置文件来实现，下面为您详细介绍配置的步骤。
### 训练配置
- 首先在yml配置文件中定义如下格式的`训练-数据处理`模块：
```yaml
TrainReader:
inputs_def: # 网络输入的定义
fields: ['image', 'gt_bbox', 'gt_class', 'gt_score']
dataset: # 数据源
!COCODataSet #序列化COCO数据源
dataset_dir: dataset/coco # 数据集根目录
anno_path: annotations/instances_train2017.json # 标注文件基于数据集根目录的相对路径
image_dir: train2017 # 图像数据基于数据集根目录的相对路径
with_background: false # 背景是否作为一类标签
sample_transforms: # 单图像数据增强算子的列表
- !DecodeImage # 序列化DecodeImage算子，详细参数设置参见源码
to_rgb: true
with_mixup: true
- !MixupImage # 序列化MixupImage算子，详细参数设置参见源码
alpha: 1.5
beta: 1.5
- !ColorDistort {} # 序列化ColorDistort算子，详细参数设置参见源码
...
batch_transforms: # 批数据数据增强算子的列表 （可选）
- !RandomShape # 序列化RandomShape算子，详细参数设置参见源码
sizes: [320, 352, 384, 416, 448, 480, 512, 544, 576, 608]
random_inter: True
...
batch_size: 8 # 以下定义见上文Reader参数列表
shuffle: true
mixup_epoch: 250
worker_num: 8
use_process: true
```
**几点说明：**
- `训练-数据处理`模块的名称统一为`TrainReader`；
- PaddleDetection的yml配置文件中，使用`!`直接序列化模块实例（可以是函数、类等）；
- `dataset`下需要序列化数据源实例，如`COCODataSet`、`VOCDataSe`和自定义的`XXXDataSet`；
- `inputs_def`的具体定义与使用请参考[模型技术文档](MODEL_TECHNICAL.md#id6)
- Reader的参数可选择性配置，如未在yml配置文件中定义，则会选取各参数在源码中的默认值。
### 评估配置
```yaml
EvalReader:
inputs_def:
fields: ['image', 'im_size', 'im_id']
dataset:
!COCODataSet
dataset_dir: dataset/coco
anno_path: annotations/instances_val2017.json
image_dir: val2017
with_background: false
sample_transforms:
- !DecodeImage
to_rgb: True
...
batch_size: 8
drop_empty: false
```
**几点说明：**
- `评估-数据处理`模块的名称统一为`EvalReader`；
- 在评估配置中，数据增强需要去除各种含有随机操作的数据处理算子与操作。
### 推理配置
```yaml
TestReader:
inputs_def:
image_shape: [3, 608, 608]
fields: ['image', 'im_size', 'im_id']
dataset:
!ImageFolder
anno_path: annotations/instances_val2017.json
with_background: false
sample_transforms:
- !DecodeImage
to_rgb: True
...
batch_size: 1
```
**几点说明：**
- `推理-数据处理`模块的名称统一为`TestReader`；
- 在推理配置中`dataset`的数据源一般都设置为`ImageFolder`数据源。ImageFolder可以指定图片的文件夹地址，将读取该文件夹下的所有图片。
到此就完成了yml配置文件中的`TrainReader`、`EvalReader`和`TestReader`的编写，您也可以将Reader部分封装到单独的yml文件`xxx_reader.yml`中，利用如下命令进行加载即可：
```yaml
_READER_: 'xxx_reader.yml'
```
加载完成后可以重写Reader中的方法，比如：
```yaml
_READER_: 'xxx_reader.yml'
TrainReader:
batch_size: 2
...
EvalReader：
...
```
这样就可以复用同一份Reader配置文件了，重写更新其中某些参数也很方便。
### 运行
在PaddleDetection的训练、评估和测试运行程序中，都通过创建Reader迭代器，然后将reader封装在DataLoader对象中，
`DataLoader`的API详见[fluid.io.DataLoader](https://www.paddlepaddle.org.cn/documentation/docs/zh/develop/api_cn/io_cn/DataLoader_cn.html#dataloader)。
具体步骤如下：
- 在[train.py](https://github.com/PaddlePaddle/PaddleDetection/blob/master/tools/train.py)、[eval.py](https://github.com/PaddlePaddle/PaddleDetection/blob/master/tools/eval.py)和[infer.py](https://github.com/PaddlePaddle/PaddleDetection/blob/master/tools/infer.py)里创建训练时的Reader：
```python
# 创建DataLoader对象
inputs_def = cfg['TestReader']['inputs_def']
_, loader = model.build_inputs(**inputs_def)
# 创建Reader迭代器
from ppdet.data.reader import create_reader
# train
train_reader = create_reader(cfg.TrainReader, max_iter=0, global_cfg=cfg)
# eval
reader = create_reader(cfg.EvalReader)
# infer
reader = create_reader(cfg.TestReader)
# 将reader设置为DataLoader数据源
loader.set_sample_list_generator(reader, place)
```
在运行程序中设置完数据处理模块后，就可以开始训练、评估与测试了，具体请参考相应运行程序python源码。
## FAQ
**Q:** 在配置文件中设置use_process=True，并且运行报错：`not enough space for reason[failed to malloc 601 pages...`
**A:** 当前Reader的共享存储队列空间不足，请增大配置文件`xxx.yml`中的`memsize`,如`memsize: 3G`->`memsize: 6G`。或者配置文件中设置`use_process=False`。

# PaddleDetection C++预测部署方案
## 本文档结构
[1.说明](#1说明)
[2.主要目录和文件](#2主要目录和文件)
[3.编译](#3编译)
[4.预测并可视化结果](#4预测并可视化结果)
## 1.说明
本目录提供一个跨平台的图像检测模型的C++预测部署方案，用户通过一定的配置，加上少量的代码，即可把模型集成到自己的服务中，完成相应的图像检测任务。
主要设计的目标包括以下四点：
- 跨平台，支持在 Windows 和 Linux 完成编译、开发和部署
- 可扩展性，支持用户针对新模型开发自己特殊的数据预处理等逻辑
- 高性能，除了`PaddlePaddle`自身带来的性能优势，我们还针对图像检测的特点对关键步骤进行了性能优化
- 支持多种常见的图像检测模型，如YOLOv3, Faster-RCNN, Faster-RCNN+FPN，用户通过少量配置即可加载模型完成常见检测任务
## 2.主要目录和文件

```
## 3.编译
支持在`Windows`和`Linux`平台编译和使用：
- [Linux 编译指南](./docs/linux_build.md)
- [Windows 使用 Visual Studio 2019 Community 编译指南](./docs/windows_vs2019_build.md)
- [Windows 使用 Visual Studio 2015 编译指南](./docs/windows_vs2015_build.md)
`Windows`上推荐使用最新的`Visual Studio 2019 Community`直接编译`CMake`项目。
## 4.预测并可视化结果
完成编译后，便生成了需要的可执行文件和链接库。这里以我们基于`faster rcnn`检测模型为例，介绍部署图像检测模型的通用流程。
### 4.1. 下载模型文件
我们提供faster rcnn，faster rcnn+fpn模型用于预测coco17数据集，可在以下链接下载：[faster rcnn示例模型下载地址](https://paddleseg.bj.bcebos.com/inference/faster_rcnn_pp50.zip)，
[faster rcnn + fpn示例模型下载地址](https://paddleseg.bj.bcebos.com/inference/faster_rcnn_pp50_fpn.zip)。
下载并解压，解压后目录结构如下：
```
faster_rcnn_pp50/
├── __model__ # 模型文件
│
└── __params__ # 参数文件
```
解压后把上述目录拷贝到合适的路径：
**假设**`Windows`系统上，我们模型和参数文件所在路径为`D:\projects\models\faster_rcnn_pp50`。
**假设**`Linux`上对应的路径则为`/root/projects/models/faster_rcnn_pp50/`。
### 4.2. 修改配置
`inference`源代码(即本目录)的`conf`目录下提供了示例基于faster rcnn的配置文件`detection_rcnn.yaml`, 相关的字段含义和说明如下：
```yaml
DEPLOY:
# 是否使用GPU预测
USE_GPU: 1
# 模型和参数文件所在目录路径
MODEL_PATH: "/root/projects/models/faster_rcnn_pp50"
# 模型文件名
MODEL_FILENAME: "__model__"
# 参数文件名
PARAMS_FILENAME: "__params__"
# 预测图片的标准输入，尺寸不一致会resize
EVAL_CROP_SIZE: (608, 608)
# resize方式，支持 UNPADDING和RANGE_SCALING
RESIZE_TYPE: "RANGE_SCALING"
# 短边对齐的长度，仅在RANGE_SCALING下有效
TARGET_SHORT_SIZE : 800
# 均值
MEAN: [0.4647, 0.4647, 0.4647]
# 方差
STD: [0.0834, 0.0834, 0.0834]
# 图片类型， rgb或者rgba
IMAGE_TYPE: "rgb"
# 像素分类数
NUM_CLASSES: 1
# 通道数
CHANNELS : 3
# 预处理器， 目前提供图像检测的通用处理类DetectionPreProcessor
PRE_PROCESSOR: "DetectionPreProcessor"
# 预测模式，支持 NATIVE 和 ANALYSIS
PREDICTOR_MODE: "ANALYSIS"
# 每次预测的 batch_size
BATCH_SIZE : 3
# 长边伸缩的最大长度，-1代表无限制。
RESIZE_MAX_SIZE: 1333
# 输入的tensor数量。
FEEDS_SIZE: 3
```
修改字段`MODEL_PATH`的值为你在**上一步**下载并解压的模型文件所放置的目录即可。更多配置文件字段介绍，请参考文档[预测部署方案配置文件说明](./docs/configuration.md)。
**注意**在使用CPU版本预测库时，`USE_GPU`的值必须设为0，否则无法正常预测。
### 4.3. 执行预测
在终端中切换到生成的可执行文件所在目录为当前目录(Windows系统为`cmd`)。
`Linux` 系统中执行以下命令：
```shell
./detection_demo --conf=conf/detection_rcnn.yaml --input_dir=images/detection_rcnn
```
`Windows` 中执行以下命令:
```shell
.\detection_demo.exe --conf=conf\detection_rcnn.yaml --input_dir=images\detection_rcnn\
```
预测使用的两个命令参数说明如下：
| 参数 | 含义 |
|-------|----------|
| conf | 模型配置的Yaml文件路径 |
| input_dir | 需要预测的图片目录 |
·
配置文件说明请参考上一步，样例程序会扫描input_dir目录下的所有图片，并为每一张图片生成对应的预测结果，输出到屏幕，并在`X`同一目录下保存到`X.pb文件`（X为对应图片的文件名）。可使用工具脚本vis.py将检测结果可视化。
**检测结果可视化**
运行可视化脚本时，只需输入命令行参数图片路径、检测结果pb文件路径、目标框阈值以及类别-标签映射文件路径即可得到可视化的图片`X.png` (tools目录下提供coco17的类别标签映射文件coco17.json)。
```bash
python vis.py --img_path=../build/images/detection_rcnn/000000087038.jpg --img_result_path=../build/images/detection_rcnn/000000087038.jpg.pb --threshold=0.1 --c2l_path=coco17.json
```

本次公布的最好单模型是一个基于Cascade RCNN的两阶段检测模型，在此基础上将Backbone替换为更加强大的SENet154模型，Deformable Conv模块以及更复杂二阶段网络结构，针对BatchSize比较小的情况增加了Group Normalization操作并同时使用了多尺度训练，最终达到了非常理想的效果。预训练模型先后分别在ImageNet和COCO数据集上进行了训练，其中在COCO数据集上训练时增加了Mask分支，其余结构与CACascade RCNN相同， 会在启动训练时自动下载。 本次公布的最好单模型是一个基于Cascade RCNN的两阶段检测模型，在此基础上将Backbone替换为更加强大的SENet154模型，Deformable Conv模块以及更复杂二阶段网络结构，针对BatchSize比较小的情况增加了Group Normalization操作并同时使用了多尺度训练，最终达到了非常理想的效果。预训练模型先后分别在ImageNet和COCO数据集上进行了训练，其中在COCO数据集上训练时增加了Mask分支，其余结构与CACascade RCNN相同， 会在启动训练时自动下载。

# PaddleDetection applied for specific scenarios
We provide some models implemented by PaddlePaddle to detect objects in specific scenarios, users can download the models and use them in these scenarios.
| Task | Algorithm | Box AP | Download |
|:---------------------|:---------:|:------:| :-------------------------------------------------------------------------------------: |
| Vehicle Detection | YOLOv3 | 54.5 | [model](https://paddlemodels.bj.bcebos.com/object_detection/vehicle_yolov3_darknet.tar) |
| Pedestrian Detection | YOLOv3 | 51.8 | [model](https://paddlemodels.bj.bcebos.com/object_detection/pedestrian_yolov3_darknet.tar) |
## Vehicle Detection
One of major applications of vehichle detection is traffic monitoring. In this scenary, vehicles to be detected are mostly captured by the cameras mounted on top of traffic light columns.
### 1. Network
The network for detecting vehicles is YOLOv3, the backbone of which is Dacknet53.
### 2. Configuration for training
PaddleDetection provides users with a configuration file [yolov3_darknet.yml](https://github.com/PaddlePaddle/PaddleDetection/blob/master/configs/yolov3_darknet.yml) to train YOLOv3 on the COCO dataset, compared with this file, we modify some parameters as followed to conduct the training for vehicle detection:
* max_iters: 120000
* num_classes: 6
* anchors: [[8, 9], [10, 23], [19, 15], [23, 33], [40, 25], [54, 50], [101, 80], [139, 145], [253, 224]]
* label_smooth: false
* nms/nms_top_k: 400
* nms/score_threshold: 0.005
* milestones: [60000, 80000]
* dataset_dir: dataset/vehicle
### 3. Accuracy
The accuracy of the model trained and evaluated on our private data is shown as followed:
AP at IoU=.50:.05:.95 is 0.545.
AP at IoU=.50 is 0.764.
### 4. Inference
Users can employ the model to conduct the inference:
```
export CUDA_VISIBLE_DEVICES=0
export PYTHONPATH=$PYTHONPATH:.
python -u tools/infer.py -c contrib/VehicleDetection/vehicle_yolov3_darknet.yml \
-o weights=https://paddlemodels.bj.bcebos.com/object_detection/vehicle_yolov3_darknet.tar \
--infer_dir contrib/VehicleDetection/demo \
--draw_threshold 0.2 \
--output_dir contrib/VehicleDetection/demo/output
```
Some inference results are visualized below:

## 快速开始
### 数据准备
我们使用[WIDER-FACE数据集](http://shuoyang1213.me/WIDERFACE/)进行训练和模型测试，官方网站提供了详细的数据介绍。
- WIDER-Face数据源:
使用如下目录结构加载`wider_face`类型的数据集：
```
dataset/wider_face/
├── wider_face_split
│ ├── wider_face_train_bbx_gt.txt
│ ├── wider_face_val_bbx_gt.txt
├── WIDER_train
│ ├── images
│ │ ├── 0--Parade
│ │ │ ├── 0_Parade_marchingband_1_100.jpg
│ │ │ ├── 0_Parade_marchingband_1_381.jpg
│ │ │ │ ...
│ │ ├── 10--People_Marching
│ │ │ ...
├── WIDER_val

│ │ │ ├── 0_Parade_marchingband_1_1045.jpg
│ │ │ │ ...
│ │ ├── 10--People_Marching
│ │ │ ...
```
- 手动下载数据集：
要下载WIDER-FACE数据集，请运行以下命令：
```
cd dataset/wider_face && ./download.sh
```
- 自动下载数据集：
如果已经开始训练，但是数据集路径设置不正确或找不到路径, PaddleDetection会从[WIDER-FACE数据集](http://shuoyang1213.me/WIDERFACE/)自动下载它们，
下载后解压的数据集将缓存在`~/.cache/paddle/dataset/`中，并且之后的训练测试会自动加载它们。
#### 数据增强方法
- **尺度变换(Data-anchor-sampling):**
具体操作是:根据随机选择的人脸高和宽，获取到$v=\sqrt{width * height}$，之后再判断`v`的值范围，其中`v`值位于缩放区间`[16,32,64,128]`
假设`v=45`，则选定`32<v<64`, 以均匀分布的概率选取`[16,32,64]`中的任意一个值。若选中`64`，则该人脸的缩放区间在`[64 / 2, min(v * 2, 64 * 2)]`中选定。
- **其他方法:** 包括随机扰动、翻转、裁剪等。具体请参考[READER.md](../advanced_tutorials/READER.md)。
### 训练与推理
训练流程与推理流程方法与其他算法一致，请参考[GETTING_STARTED_cn.md](../tutorials/GETTING_STARTED_cn.md)。
**注意:**
- `BlazeFace`和`FaceBoxes`训练是以每卡`batch_size=8`在4卡GPU上进行训练(总`batch_size`是32),并且训练320000轮
(如果你的GPU数达不到4，请参考[学习率计算规则表](../tutorials/GETTING_STARTED_cn.html#faq))。
- 人脸检测模型目前我们不支持边训练边评估。
### 评估
目前我们支持在`WIDER FACE`数据集和`FDDB`数据集上评估。首先运行`tools/face_eval.py`生成评估结果文件，其次使用matlab（WIDER FACE）
或OpenCV（FDDB）计算具体的评估指标。
其中，运行`tools/face_eval.py`的参数列表如下：
- `-f` 或者 `--output_eval`: 评估生成的结果文件保存路径，默认是： `output/pred`；
- `-e` 或者 `--eval_mode`: 评估模式，包括 `widerface` 和 `fddb`，默认是`widerface`；
- `--multi_scale`: 如果在命令中添加此操作按钮，它将选择多尺度评估。默认值为`False`，它将选择单尺度评估。
#### 在WIDER-FACE数据集上评估
评估并生成结果文件：
```
export CUDA_VISIBLE_DEVICES=0
export PYTHONPATH=$PYTHONPATH:.
python -u tools/face_eval.py -c configs/face_detection/blazeface.yml \
-o weights=output/blazeface/model_final/ \
--eval_mode=widerface
```
评估完成后，将在`output/pred`中生成txt格式的测试结果。
- 下载官方评估脚本来评估AP指标：
```
wget http://mmlab.ie.cuhk.edu.hk/projects/WIDERFace/support/eval_script/eval_tools.zip
unzip eval_tools.zip && rm -f eval_tools.zip
```
- 在`eval_tools/wider_eval.m`中修改保存结果路径和绘制曲线的名称：
```
# Modify the folder name where the result is stored.
pred_dir = './pred';
# Modify the name of the curve to be drawn
legend_name = 'Fluid-BlazeFace';
```
- `wider_eval.m` 是评估模块的主要执行程序。运行命令如下：
```
matlab -nodesktop -nosplash -nojvm -r "run wider_eval.m;quit;"
```
#### 在FDDB数据集上评估
我们提供了一套FDDB数据集的评估流程(目前仅支持Linux系统)，其他具体细节请参考[FDDB官网](http://vis-www.cs.umass.edu/fddb/)。
- 1)下载安装opencv：
下载OpenCV: 进入[OpenCV library](https://opencv.org/releases/)手动下载
安装OpenCV：请参考[OpenCV官方安装教程](https://docs.opencv.org/master/d7/d9f/tutorial_linux_install.html)通过源码安装。
- 2)下载数据集、评估代码以及格式化数据：
```
./dataset/fddb/download.sh
```
- 3)编译FDDB评估代码：
进入`dataset/fddb/evaluation`目录下，修改MakeFile文件中内容如下：
```
evaluate: $(OBJS)
$(CC) $(OBJS) -o $@ $(LIBS)
```
修改`common.hpp`中内容为如下形式：
```
#define __IMAGE_FORMAT__ ".jpg"
//#define __IMAGE_FORMAT__ ".ppm"
#define __CVLOADIMAGE_WORKING__
```
根据`grep -r "CV_RGB"`命令找到含有`CV_RGB`的代码段，将`CV_RGB`改成`Scalar`，并且在cpp中加入`using namespace cv;`，
然后编译：
```
make clean && make
```
- 4)开始评估:
修改config文件中`dataset_dir`和`annotation`字段内容：
```
EvalReader:
...
dataset:
dataset_dir: dataset/fddb
anno_path: FDDB-folds/fddb_annotFile.txt
...
```
评估并生成结果文件：
```
python -u tools/face_eval.py -c configs/face_detection/blazeface.yml \
-o weights=output/blazeface/model_final/ \
--eval_mode=fddb
```
评估完成后，将在`output/pred/pred_fddb_res.txt`中生成txt格式的测试结果。
生成ContROC与DiscROC数据：
```
cd dataset/fddb/evaluation
./evaluate -a ./FDDB-folds/fddb_annotFile.txt \
-f 0 -i ./ -l ./FDDB-folds/filePath.txt -z .jpg \
-d {RESULT_FILE} \
-r {OUTPUT_DIR}
```
**注意:**
(1)`RESULT_FILE`是`tools/face_eval.py`输出的FDDB预测结果文件；
(2)`OUTPUT_DIR`是FDDB评估输出结果文件前缀，会生成两个文件`{OUTPUT_DIR}ContROC.txt`、`{OUTPUT_DIR}DiscROC.txt`；
(3)参数用法及注释可通过执行`./evaluate --help`来获取。
## 算法细节
### BlazeFace
**简介:**
[BlazeFace](https://arxiv.org/abs/1907.05047) 是Google Research发布的人脸检测模型。它轻巧并且性能良好，
专为移动GPU推理量身定制。在旗舰设备上，速度可达到200-1000+FPS。
**特点:**
- 锚点策略在8×8（输入128x128）的特征图上停止，在该分辨率下每个像素点6个锚点；
- 5个单BlazeBlock和6个双BlazeBlock：5×5 depthwise卷积，可以保证在相同精度下网络层数更少；
- 用混合策略替换非极大值抑制算法，该策略将边界框的回归参数估计为重叠预测之间的加权平均值。
**版本信息:**
- 原始版本: 参考原始论文复现；
- Lite版本: 使用3x3卷积替换5x5卷积，更少的网络层数和通道数；
- NAS版本: 使用神经网络搜索算法构建网络结构，相比于`Lite`版本，NAS版本需要更少的网络层数和通道数。
### FaceBoxes
**简介:**
[FaceBoxes](https://arxiv.org/abs/1708.05234) 由Shifeng Zhang等人提出的高速和高准确率的人脸检测器，
被称为“高精度CPU实时人脸检测器”。 该论文收录于IJCB（2017）。
**特点:**
- 锚点策略分别在20x20、10x10、5x5（输入640x640）执行，每个像素点分别是3、1、1个锚点，对应密度系数是`1, 2, 4`(20x20)、4(10x10)、4(5x5)；
- 在基础网络中个别block中使用CReLU和inception的结构；
- 使用密度先验盒（density_prior_box）可提高检测精度。
**版本信息:**
- 原始版本: 参考原始论文复现；
- Lite版本: 使用更少的网络层数和通道数，具体可参考[代码](https://github.com/PaddlePaddle/PaddleDetection/blob/master/ppdet/modeling/architectures/faceboxes.py)。

**English document please refer:** [PaddleDetection C++ deployment](../docs/advanced_tutorials/inference/DEPLOYMENT.md)
## 本文档结构
[1.说明](#1说明)
[2.主要目录和文件](#2主要目录和文件)
[3.编译](#3编译)
[4.预测并可视化结果](#4预测并可视化结果)
## 1.说明
本目录提供一个跨平台的图像检测模型的C++预测部署方案，用户通过一定的配置，加上少量的代码，即可把模型集成到自己的服务中，完成相应的图像检测任务。
主要设计的目标包括以下四点：
- 跨平台，支持在 Windows 和 Linux 完成编译、开发和部署
- 可扩展性，支持用户针对新模型开发自己特殊的数据预处理等逻辑
- 高性能，除了`PaddlePaddle`自身带来的性能优势，我们还针对图像检测的特点对关键步骤进行了性能优化
- 支持多种常见的图像检测模型，如YOLOv3, Faster-RCNN, Faster-RCNN+FPN，用户通过少量配置即可加载模型完成常见检测任务
## 2.主要目录和文件

```
## 3.编译
支持在`Windows`和`Linux`平台编译和使用：
- [Linux 编译指南](./docs/linux_build.md)
- [Windows 使用 Visual Studio 2019 Community 编译指南](./docs/windows_vs2019_build.md)
- [Windows 使用 Visual Studio 2015 编译指南](./docs/windows_vs2015_build.md)
`Windows`上推荐使用最新的`Visual Studio 2019 Community`直接编译`CMake`项目。
## 4.预测并可视化结果
完成编译后，便生成了需要的可执行文件和链接库。这里以我们基于`faster rcnn`检测模型为例，介绍部署图像检测模型的通用流程。
### 4.1. 下载模型文件
我们提供faster rcnn，faster rcnn+fpn模型用于预测coco17数据集，可在以下链接下载：[faster rcnn示例模型下载地址](https://paddleseg.bj.bcebos.com/inference/faster_rcnn_pp50.zip)，
[faster rcnn + fpn示例模型下载地址](https://paddleseg.bj.bcebos.com/inference/faster_rcnn_pp50_fpn.zip)。
下载并解压，解压后目录结构如下：
```
faster_rcnn_pp50/
├── __model__ # 模型文件
│
└── __params__ # 参数文件
```
解压后把上述目录拷贝到合适的路径：
**假设**`Windows`系统上，我们模型和参数文件所在路径为`D:\projects\models\faster_rcnn_pp50`。
**假设**`Linux`上对应的路径则为`/root/projects/models/faster_rcnn_pp50/`。
### 4.2. 修改配置
`inference`源代码(即本目录)的`conf`目录下提供了示例基于faster rcnn的配置文件`detection_rcnn.yaml`, 相关的字段含义和说明如下：
```yaml
DEPLOY:
# 是否使用GPU预测
USE_GPU: 1
# 模型和参数文件所在目录路径
MODEL_PATH: "/root/projects/models/faster_rcnn_pp50"
# 模型文件名
MODEL_FILENAME: "__model__"
# 参数文件名
PARAMS_FILENAME: "__params__"
# 预测图片的标准输入，尺寸不一致会resize
EVAL_CROP_SIZE: (608, 608)
# resize方式，支持 UNPADDING和RANGE_SCALING
RESIZE_TYPE: "RANGE_SCALING"
# 短边对齐的长度，仅在RANGE_SCALING下有效
TARGET_SHORT_SIZE : 800
# 均值
MEAN: [0.4647, 0.4647, 0.4647]
# 方差
STD: [0.0834, 0.0834, 0.0834]
# 图片类型， rgb或者rgba
IMAGE_TYPE: "rgb"
# 像素分类数
NUM_CLASSES: 1
# 通道数
CHANNELS : 3
# 预处理器， 目前提供图像检测的通用处理类DetectionPreProcessor
PRE_PROCESSOR: "DetectionPreProcessor"
# 预测模式，支持 NATIVE 和 ANALYSIS
PREDICTOR_MODE: "ANALYSIS"
# 每次预测的 batch_size
BATCH_SIZE : 3
# 长边伸缩的最大长度，-1代表无限制。
RESIZE_MAX_SIZE: 1333
# 输入的tensor数量。
FEEDS_SIZE: 3
```
修改字段`MODEL_PATH`的值为你在**上一步**下载并解压的模型文件所放置的目录即可。更多配置文件字段介绍，请参考文档[预测部署方案配置文件说明](./docs/configuration.md)。
**注意**在使用CPU版本预测库时，`USE_GPU`的值必须设为0，否则无法正常预测。
### 4.3. 执行预测
在终端中切换到生成的可执行文件所在目录为当前目录(Windows系统为`cmd`)。
`Linux` 系统中执行以下命令：
```shell
./detection_demo --conf=conf/detection_rcnn.yaml --input_dir=images/detection_rcnn
```
`Windows` 中执行以下命令:
```shell
.\detection_demo.exe --conf=conf\detection_rcnn.yaml --input_dir=images\detection_rcnn\
```
预测使用的两个命令参数说明如下：
| 参数 | 含义 |
|-------|----------|
| conf | 模型配置的Yaml文件路径 |
| input_dir | 需要预测的图片目录 |
·
配置文件说明请参考上一步，样例程序会扫描input_dir目录下的所有图片，并为每一张图片生成对应的预测结果，输出到屏幕，并在`X`同一目录下保存到`X.pb文件`（X为对应图片的文件名）。可使用工具脚本vis.py将检测结果可视化。
**检测结果可视化**
运行可视化脚本时，只需输入命令行参数图片路径、检测结果pb文件路径、目标框阈值以及类别-标签映射文件路径即可得到可视化的图片`X.png` (tools目录下提供coco17的类别标签映射文件coco17.json)。
```bash
python vis.py --img_path=../build/images/detection_rcnn/000000087038.jpg --img_result_path=../build/images/detection_rcnn/000000087038.jpg.pb --threshold=0.1 --c2l_path=coco17.json
```
