Disentangled Representation Learning for 3D Face Shape

This repository is the implementation of our CVPR 2019 paper "Disentangled Representation Learning for 3D Face Shape"

Authors: Zihang Jiang ,Qianyi Wu, Keyu Chen and Juyong Zhang .

Our Proposed Framework

Result Examples

We can manipulate 3D face shape in expression and identity code space.

Usage

Dataset

Please download FaceWareHouse dataset and extract it into the corresponding dir like data/FaceWarehouse_Data.

Requirements

1. Basic Environment

tensorflow-gpu = 1.9.0

Keras = 2.2.2

openmesh (both python version which can be installed through pip install openmesh, and compiled version are required)

1.5 quick start

For convenience, we included repos for get_dr and get_mesh in third party folder and provided scripts for easy install. See readme in third party folder for detail.

2. Requirements for Data Processing (About Deformation Representation Feature)

  1. We provide a python interface for obtaining Deformation Representation (DR) Feature. Code are avaliable at Here to generate DR feature for each obj file by specific one reference mesh. Replace the get_dr.cpython-36m-x86_64-linux-gnu.so with compiled one and run python get_fwh_dr.py After that, you can change the data_path and data_format in src/data_utils.py.

  2. To recover mesh from DR feature, you need to compile get_mesh, and replace the get_mesh.cpython-36m-x86_64-linux-gnu.so in src folder.

  3. Also, python version of libigl is needed for mesh-IO and you need to replace the pyigl.so in src folder if the current one does not match your environment.

After all requirements are satisfied, you can use following command to train and test the model.

Training

Run following command to generate training and testing data for 3D face DR learning

python src/data_utils.py

We have provided DR feature of expression mesh on Meanface we used in this project on here.

Run this command to pretrain identity branch

python main.py -m gcn_vae_id -e 20

Run following command to pretrain expression branch

python main.py -m gcn_vae_exp -e 20

Run following command for end_to_end training the whole framework

python main.py -m fusion_dr -e 20

Testing

You can test on each branch and the whole framework like

python main.py -m fusion_dr -l -t

Our pretrained model can be found here.

Evaluation

The measurement.py and STED folder is for computation of numerical result mentioned in our paper, including two reconstruction metrics and two decompostion metrics.

Notes

  1. if you train the model on your own dataset(for which topology is different from FaceWarehouse mesh), you have to recompute Mean_Face.obj and expression meshes on mean face as mentioned in our paper and regenerate the FWH_adj_matrix.npz in data/disentagle folder using src/igl_test.py.
  2. We will release srcipts for data augmentation method metioned in our paper. You could put the augmented interpolated data in data/disentangle/Interpolated_results
  3. Currently we have fully tested this package on Ubuntu 16.04 LTS environment with CUDA 9.0. Windows and MacOS are not ensured working.
  4. Errors like Unknown CMake command "pybind11_add_module" you may encounter while building get_mesh and get_dr can be solved by
git submodule init
git submodule update --recursive
