Latest Features

Dec 2018: PoseFlow(General Version) released! Support ANY DATASET and pose tracking results visualization.
Oct 2018: Support generating correspondence files with ORB(OpenCV), 3X FASTER and no need to compile DeepMatching library.

Requirements

Python 2.7.13
OpenCV 3.4.2.16
OpenCV-contrib 3.4.2.16
tqdm 4.19.8

Installation

Download PoseTrack Dataset from PoseTrack to AlphaPose/PoseFlow/posetrack_data/
(Optional) Use DeepMatching to extract dense correspondences between adjcent frames in every video, please refer to DeepMatching Compile Error to compile DeepMatching correctly

pip install -r requirements.txt

cd deepmatching
make clean all
make
cd ..

For Any Datasets (General Version)

Using AlphaPose to generate multi-person pose estimation results.

# pytorch version
python demo.py --indir ${image_dir}$ --outdir ${results_dir}$

# torch version
./run.sh --indir ${image_dir}$ --outdir ${results_dir}$

Run pose tracking

# pytorch version
python tracker-general.py --imgdir ${image_dir}$ 
                          --in_json ${results_dir}$/alphapose-results.json 
                          --out_json ${results_dir}$/alphapose-results-forvis-tracked.json
                          --visdir ${render_dir}$

# torch version
python tracker-general.py --imgdir ${image_dir}$ 
                          --in_json ${results_dir}$/POSE/alpha-pose-results-forvis.json 
                          --out_json ${results_dir}$/POSE/alpha-pose-results-forvis-tracked.json
                          --visdir ${render_dir}$

For PoseTrack Dataset Evaluation (Paper Baseline)

Using AlphaPose to generate multi-person pose estimation results on videos with format like alpha-pose-results-sample.json.
Using DeepMatching/ORB to generate correspondence files.

# Generate correspondences by DeepMatching
# (More Robust but Slower)
python matching.py --orb=0 

or

# Generate correspondences by Orb
# (Faster but Less Robust)
python matching.py --orb=1

Run pose tracking

python tracker-baseline.py --dataset=val/test  --orb=1/0

Evaluation

Original poseval has some instructions on how to convert annotation files from MAT to JSON.

Evaluate pose tracking results on validation dataset:

git clone https://github.com/leonid-pishchulin/poseval.git --recursive
cd poseval/py && export PYTHONPATH=$PWD/../py-motmetrics:$PYTHONPATH
cd ../../
python poseval/py/evaluate.py --groundTruth=./posetrack_data/annotations/val \
                    --predictions=./${track_result_dir}/ \
                    --evalPoseTracking --evalPoseEstimation
