This code is tested on Tensorflow 1.3. Requirements (including tensorflow) can be installed using:

pip install -r requirements.txt

Install mesh processing libraries fromMPI-IS/mesh.

Download the data from theProject Page.

Preprocess the data

python processData.py --data<PATH_OF_RAW_DATA> --save_path<PATH_TO_SAVE_PROCESSED DATA>

Data pre-processing creates numpy files for the interpolation experiment and extrapolation experiment (Section X of the paper).This creates 13 different train and test files.sliced_[train|test] is for the interpolation experiment.<EXPRESSION>_[train|test] are for cross validation cross 12 different expression sequences.

To train, specify a name, and choose a particular train test split. For example,

python main.py --data data/sliced --name sliced

To test, specify a name, and data. For example,

python main.py --data data/sliced --name sliced --modetest

Run the following script. The models are slightly better (~1% on average) than ones reported in the paper.

sh generateErrors.sh

To sample faces from the latent space, specify a model and data. For example,

python main.py --data data/sliced --name sliced --mode latent

A face template pops up. You can then use the keysqwertyui to sample faces by moving forward in each of the 8 latent dimensions. Useasdfghjk to move backward in the latent space.

For more flexible usage, refer tolib/visualize_latent_space.py.

CAPE (CVPR 2020): Based on CoMA, we build a conditional Mesh-VAE-GAN to learn the clothing deformation from the SMPL body model, making a generative, animatable model of people in clothing. A large-scale mesh dataset of clothed humans in motion is also included!
