Dataset and Preprocessing

FLAME Model

Our method relies on FLAME face prior model(2023 version). Please download FLAME assets from flame project, put flame2023.pkl(versions w/ jaw rotation) to flame_model/assets/flame/flame2023.pkl and put FLAME_masks.pkl to flame_model/assets/flame/FLAME_masks.pkl

Test Data

We test our method on NeRSemble multi-view human head videos dataset, which is preprocessed by GaussianAvatars(CVPR2024), please refers to GaussianAvatars to download test data. Unlike GaussianAvatars, we use free performance sequences as the test set and other video segments as the training set.

Usage

Preprocess

# cluster expressions, please modify the dataset root path and test person id 
python expr_analyze.py

#extract jaw rotation basis
python preprocess_jaw.py

Training

./run.sh

Rendering

./render.sh

Acknowledgments

This work was heavily inspired by GaussianAvatars. We use NeRSemble for testing. We also borrow code from the following repositories. Thanks to their impressive work!
