This is a keras implementation of Realtime Multi-Person Pose Estimation.

Prerequisites

0. Keras and Tensorflow (tested on Linux machine)
1. Python3
2. GPU with at least 11GB memory
3. More than 250GB of disk space for training data

Please also install the following packages:

$ sudo apt-get install libboost-all-dev libhdf5-serial-dev libzmq3-dev libopencv-dev python-opencv python3-tk python-imaging
$ sudo pip3 install Cython scikit-image pandas zmq h5py opencv-python IPython configobj

Download COCO 2014 Dataset

Please download the COCO dataset and the official COCO evaluation API. Go to folder dataset and simply run the following commands:

$ cd dataset
$ ./step1_download_coco2014.sh
$ ./step2_setup_coco_api.sh

Prepare Training Data

Before model training, we convert the images to the specific data format for efficient training. We generate the heatmaps, part affinity maps, and then convert them to HDF5 files. Go to the folder training, and run the scripts. The process takes around 2 hours.

$ cd training
$ python3 generate_masks_coco2014.py
$ python3 generate_hdf5_coco2014.py

After this, you will generate train_dataset_2014.h5 and val_dataset_2014.h5. The files are about 182GB and 3.8GB, respectively.

Training

Simply go to folder training and run the training script:

$ cd training
$ python3 train_pose.py

Evaluation on COCO Keypoint Datasets

Please go to folder eval and run the evaluation script. eval_model=0: single-scale evaluation. eval_model=1: multi-scale evaluation (as described in Openpose's paper).

$ cd eval
$ python3 eval_coco2014_multi_modes.py --eval_method 0
$ python3 eval_coco2014_multi_modes.py --eval_method 1

Evaluation Summary

We empirically trained the model for 100 epochs (2 weeks) and achieved comparable performance to the results reported in the original paper. We also compared with the original implementation which is online avialable. Note that the validation list COCO2014-Val-1K is provided by the official Openpose.

Method	Validation	AP
Openpose paper	COCO2014-Val-1k	58.4
Openpose model	COCO2014-Val-1k	56.3
This repo	COCO2014-Val-1k	58.2

We also evaluated the performance on the full COCO2014 validation set.

Method	Validation	AP
Openpose model	COCO2014-Val	58.9
This repo	COCO2014-Val	59.0
