Requirements

Conda environments

conda create -n ACR python==3.8.8  
conda activate ACR 
conda install -n ACR pytorch==1.10.0 torchvision==0.11.1 cudatoolkit=10.2 -c pytorch
pip install -r requirements.txt

For rendering and visualization on headless server, please consider install pytorch3d follow the official instruction and set renderer to pytorch3d in configs/demo.yml. Note that pyrender can only be used on desktop.

Pre-trained model and data

• Register and download MANO model. Put MANO_LEFT.pkl and MANO_RIGHT.pkl in mano/
• Download pre-trained weights from here (update on 3.28) and put it in checkpoints/

Demo

Note: use -t to smooth your results. We provide examples in demos/

# Run a real-time demo:
python -m acr.main --demo_mode webcam -t

# Run on a single image:
python -m acr.main --demo_mode image --inputs <PATH_TO_IMAGE>

# Run on a folder of images:
python -m acr.main --demo_mode folder -t --inputs <PATH_TO_FOLDER> 

# Run on a video:
python -m acr.main --demo_mode video -t --inputs <PATH_TO_VIDEO> 

Finally, the visualization will be saved in demos_outputs/. In video or folder mode, the results will also be saved as <FILENAME>_output.mp4.

Acknowledgement

The pytorch implementation of MANO is based on manopth. We use some parts of the great code from ROMP. For MANO segmentation and rendering, we follow zc-alexfan. We thank all the authors for their impressive works!
