[Paper]

Installation
Create conda environment and install dependencies.
conda create -n closeint python=3.8
pip install torch==2.0.1 torchvision==0.15.2 torchaudio==2.0.2 --index-url https://download.pytorch.org/whl/cu118
pip install -r requirements.txt
You may also require BVH_CUDA for collision detection.
Download the official SMPL model from SMPL and SMPLify website and place them in data/smpl.
Training on Hi4D
Step1:
Following other video-based methods, we extract image features as network input for training efficiency. The preprocessed annotations can be obtained from Baidu Netdisk or Google Drive. You should also download original images from Hi4D website. The folder structure is shown as follows:
./data
├── dataset
│ ├── Hi4D
│ │ ├── annot
│ │ └── images
├── smpl
│ ├── SMPL_MALE.pkl
│ └── SMPL_FEMALE.pkl
│ └── SMPL_NEUTRAL.pkl
├── checkpoint.pkl
Step2:
python train.py --config cfg_files/config.yaml
Evaluation
Step1:
Download checkpoint file from Baidu Netdisk or Google Drive. You may also require SDF loss for evaluating penetration.
Step2:
python eval.py --config cfg_files/eval.yaml
Demo
Download demo_models from Baidu Netdisk and place them in data. Then, compile roi_align from Alphapose.
python demo.py
