Dependencies

Requirements:

• python3.6
• numpy
• pytorch==1.1.0
• pymesh

Our code has been tested with Python 3.6, Pytorch1.1.0, CUDA 9.0 on Ubuntu 16.04.

Generating the data

We provide our code data_generation.py based on https://github.com/CalciferZh/SMPL and for more information about SMPL, please check https://smpl.is.tue.mpg.de/. The meshes with clothes are from https://virtualhumans.mpi-inf.mpg.de/mgn/.

Data and Pre-trained model

We provide dataset and pre-trained model used in our paper, please download data from data link, and download model weights from model link. The test data file lists are also provided, the mesh file order in file lists are identiy pose gt. (Backup links: Google Drive)

Running the demo

We provide the pre-trained model for the original method and maxpooling method and also two meshes for test. For you own data, please train the model by yourself, because the pose parameter space may be different. For human meshes with clothes, we recommend the max-pooling method.

python demo.py

Training

We provide both original and max-pooling methods. (Max-pooling one is recommended). The original method has slightly better quantitative results. The max-pooling method is more convenient when dealing with identity and pose meshes with different number of vertices and this method produces smoother results.

python train.py

Evaluation

evaluate.py is the code for evaluation.
