Human Pose Refiner

This is the inference code used in the Human Pose Refiner algorithm introduced in the HumanPoseRefiner publication:

Mihai Fieraru, Anna Khoreva, Leonid Pishchulin and Bernt Schiele - Learning to Refine Human Pose Estimation - In The IEEE Conference on Computer Vision and Pattern Recognition (CVPR) Workshops, 2018

The algorithm takes as input an image and an estimated pose and refines the positions of the joints (outputs a more precise 2d pose).
We provide code to run the algorithm on predictions on the PoseTrack dataset. The refinement algorithm is applied per one pose at a time, independent of the other pose predictions in the image/video.

Install

The code is tested with python3 and Tensorflow v1.5. We recommend using virtualenv to create an environment and install the required packages (including TF) using the associated pip. See official documentation here: https://www.tensorflow.org/install/pip .

# install tensorflow v1.5
pip install -U https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow_gpu-1.5.0-cp35-cp35m-linux_x86_64.whl

# install required packages
pip install -U easydict numpy scipy scikit-image init_weights: /BS/mihai/work/experiments/ddpose_track_train/exp20cc/snapshot-515000

Choose a path where you'd like to clone the code by setting the environment variable HUMAN_POSE_REFINER accordingly.

# HUMAN_POSE_REFINER=/path/to/human-pose-refiner
git clone git@github.com:mihaifieraru/human-pose-refiner.git $HUMAN_POSE_REFINER

Download the weights of the model used for refining predictions on the PoseTrack dataset.

# download snapshot-515000.zip from https://drive.google.com/open?id=1BEDB_zX8-0XrpdBimYAN4GwaAVAUrrBJ
cp snapshot-515000.zip $HUMAN_POSE_REFINER/model/
cd $HUMAN_POSE_REFINER/model/
unzip snapshot-515000.zip
rm snapshot-515000.zip

Download the PoseTrack 2018 Dataset (images and annotations) from https://posetrack.net/users/download.php . It should be organized in the following way:

$HUMAN_POSE_REFINER/
    --data
        --posetrack_data_v2
            --annotations
                --test
                --train
                --val
            --images
                --test
                --train
                --val

Set path to the posetrack-v2 predictions that you want to refine. This should be a folder containing the json files that are in the same format required by the evaluation https://github.com/leonid-pishchulin/poseval .

vim $HUMAN_POSE_REFINER/exp/improve-mota-posetrack-v2/pose_cfg.yaml
# set the parameter dataset:

Run

Refine predictions such that the MOTA score is improved:

# activate the environment containing TF 1.5 and the required packages
# set gpu ID in CUDA_VISIBLE_DEVICES. 
cd $HUMAN_POSE_REFINER/exp/improve-mota-posetrack-v2/
CUDNN_USE_AUTOTUNE=0 CUDA_VISIBLE_DEVICES=0 python3 $HUMAN_POSE_REFINER/run_dataset.py

Refine predictions such that the MAP score is improved:

# activate the environment containing TF 1.5 and the required packages
# set gpu ID in CUDA_VISIBLE_DEVICES. 
cd $HUMAN_POSE_REFINER/exp/improve-map-posetrack-v2/
CUDNN_USE_AUTOTUNE=0 CUDA_VISIBLE_DEVICES=0 python3 $HUMAN_POSE_REFINER/run_dataset.py

A significant amount of the code is borrowed from the following repository https://github.com/eldar/pose-tensorflow.
