This is a pytroch version of Realtime Multi-Person Pose Estimation, origin code is https://github.com/ZheC/Realtime_Multi-Person_Pose_Estimation and https://github.com/last-one/pytorch_realtime_multi-person_pose_estimation. Thanks to ZheC and last-one for providing the codes.

Code for reproducing CVPR 2017 Oral paper using pytorch

 

The result is generated by the model, which has trained 30 epoches.

1.preprocessing: some scripts for preprocessing data.

2.training: some scripts for training networks.

3.testing: the test script and example.

4.caffe2pytorch: the script for converting.

5.caffe_model: caffe model

Pytorch: 0.2.0_3

Caffe: If you want to convert the caffemodel by your own.

Mytransforms.py: some transformer.

transformer the image, mask, keypoints and center points, together.

CocoFolder.py: to read data for network.

It will generate the PAFs vector and heatmap when get the image.

The PAFs vector's format as follow:

POSE_COCO_PAIRS = {
	{3,  4},
	{4,  5},
	{6,  7},
	{7,  8},
	{9,  10},
	{10, 11},
	{12, 13},
	{13, 14},
	{1,  2},
	{2,  9},
	{2,  12},
	{2,  3},
	{2,  6},
	{3,  17},
	{6,  18},
	{1,  16},
	{1,  15},
	{16, 17},
	{15, 18},
}

Where each index is the key value corresponding to each part in POSE_COCO_BODY_PARTS

utils.py: some common functions, such as adjust learning rate, read configuration and etc.

visualize_input.ipynb: the script to vierfy the validaity of preprocessing and generating heatmap and vectors. It shows some examples.

pose_estimation.py: the structure of networks.

The first 10 layers equals to VGG-19, so if set pretrained as True, it will be initialized by the VGG-19. And the stage is 6. The first stage has 5 layers (3 3x3conv + 2 1x1conv) and the remainder stages have 7 layers (5 3x3conv + 2 1x1conv).

TODO: the stage is adjustable.

• Download the data set, annotations and COCO official toolbox
• Go to the "preprocessing" folder cd preprocessing.
• Generate json file and masks python generate_json_mask,py.
• Go to the "training" folder cd ../training.
• Set the train parameters in "config.yml".
• Set the train data dir , train mask dir, train json filepath and val data dir, val mask dir, val json filepath.
• Train the model sh train.sh.

• When you want to train some other datasets, please change the code: Mytransforms.py, CocoFolder.py to correspond to your datasets. Besides, please ensure '0' corresponds to background.
• The converted model and my code are used BGR to train and test images.
