This is the official repository for our ECCV 2024 paper TalkingGaussian: Structure-Persistent 3D Talking Head Synthesis via Gaussian Splatting.

Paper | Project | Video

Tested on Ubuntu 18.04, CUDA 11.3, PyTorch 1.12.1

git clone git@github.com:Fictionarry/TalkingGaussian.git --recursive

conda env create --file environment.yml
conda activate talking_gaussian
pip install "git+https://github.com/facebookresearch/pytorch3d.git"
pip install tensorflow-gpu==2.8.0

If encounter installation problem from the diff-gaussian-rasterization or gridencoder, please refer to gaussian-splatting and torch-ngp.

• Prepare face-parsing model and the 3DMM model for head pose estimation.

  bash scripts/prepare.sh

• Download 3DMM model from Basel Face Model 2009:

  # 1. copy 01_MorphableModel.mat to data_util/face_tracking/3DMM/
  # 2. run following
  cd data_utils/face_tracking
  python convert_BFM.py

• Prepare the environment for EasyPortrait:

  # prepare mmcv
  conda activate talking_gaussian
  pip install -U openmim
  mim install mmcv-full==1.7.1
  
  # download model weight
  cd data_utils/easyportrait
  wget "https://rndml-team-cv.obs.ru-moscow-1.hc.sbercloud.ru/datasets/easyportrait/experiments/models/fpn-fp-512.pth"

• Users are encouraged to use this code responsibly and ethically.

Here we provide two video clips used in our experiments, which are captured from YouTube. Please respect the original content creators' rights and comply with YouTube’s copyright policies in the usage.

Other used videos can be found from GeneFace and AD-NeRF.

• Put training video under data/<ID>/<ID>.mp4.

  The video must be 25FPS, with all frames containing the talking person. The resolution should be about 512x512, and duration about 1-5 min.

• Run script to process the video.

  python data_utils/process.py data/<ID>/<ID>.mp4

• Obtain Action Units

  Run FeatureExtraction in OpenFace, rename and move the output CSV file to data/<ID>/au.csv.

• Generate tooth masks

  export PYTHONPATH=./data_utils/easyportrait 
  python ./data_utils/easyportrait/create_teeth_mask.py ./data/<ID>

In our paper, we use DeepSpeech features for evaluation.

• DeepSpeech

  python data_utils/deepspeech_features/extract_ds_features.py --input data/<name>.wav # saved to data/<name>.npy

• HuBERT

  Similar to ER-NeRF, HuBERT is also available. Recommended for situations if the audio is not in English.

  Specify --audio_extractor hubert when training and testing.

  python data_utils/hubert.py --wav data/<name>.wav # save to data/<name>_hu.npy
  

# If resources are sufficient, partially parallel is available to speed up the training. See the script.
bash scripts/train_xx.sh data/<ID> output/<project_name> <GPU_ID>

# saved to output/<project_name>/test/ours_None/renders
python synthesize_fuse.py -S data/<ID> -M output/<project_name> --eval  

python synthesize_fuse.py -S data/<ID> -M output/<project_name> --use_train --audio <preprocessed_audio_feature>.npy

This code is developed on gaussian-splatting with simple-knn, and a modified diff-gaussian-rasterization. Partial codes are from RAD-NeRF, DFRF, GeneFace, and AD-NeRF. Teeth mask is from EasyPortrait. Thanks for these great projects!
