MRT

This is an implementation of the NeurIPS'21 paper "Multi-Person 3D Motion Prediction with Multi-Range Transformers".

Please check our paper and the project webpage for more details.

We will also provide the code to fit our skeleton representation data to SMPL data.

Datasets

We provide the data preprocessing code of CMU-Mocap and MuPoTS-3D (others are coming soon). For CMU-Mocap, the dictionary tree is like

   mocap
   ├── amc_parser.py
   ├── mix_mocap.py
   ├── preprocess_mocap.py
   ├── vis.py
   └── all_asfamc
       └── subjects
           ├── 01
           ...

After dowloading the original data, please try

python ./mocap/preprocess_mocap.py
python ./mocap/mix_mocap.py

For MuPoTS-3D, the dictionary tree is like

   mupots3d
   ├── preprocess_mupots.py
   ├── vis.py
   └── data
       ├── TS1
       ...

After dowloading the original data, please try

python ./mocap/preprocess_mupots.py

Training

To train our model, please try

python train_mrt.py

Evaluation and visualization

We provide the evaluation and visualization code in test.py
