LHM_Track is a video processing pipeline for building LHM training dataset. It generates multiple labels from human centric video, such as segmentation, 2D keypoints, SMPL-X parameters and FLAME parameters.

If you find our work useful for you, please ⭐ star LHM and LHM_Track repositories to help us reach more people.

[April 8, 2025] Release the pipeline for building LHM training dataset.

Clone the repository.

git clone https://github.com/aigc3d/LHM_Track.git
cd LHM_Track

The environment is not same as the LHM repo. Please create a new conda environment or python venv.

# create new environment
conda create -n lhm_track python=3.10
conda activate lhm_track
# or
# python -m venv lhm_track
# source lhm_track/bin/activate
# cuda 12.1
sh ./install_cu121.sh
# cuda 11.8
sh ./install_cu118.sh

The installation has been tested with python3.10, CUDA 12.1 or CUDA 11.8.

Download basic model weights. If you've downloaded them in LHM repo, you can copy/link the pretrained_models folder into this repo.

# Download prior model weights
wget https://virutalbuy-public.oss-cn-hangzhou.aliyuncs.com/share/aigc3d/data/LHM/LHM_prior_model.tar 
tar -xvf LHM_prior_model.tar 

Download extra model weights.
