Given the raw audio input and a neutral 3D face mesh, our proposed end-to-end Transformer-based architecture, FaceFormer, can autoregressively synthesize a sequence of realistic 3D facial motions with accurate lip movements.

Environment

• Ubuntu 18.04.1
• Python 3.7
• Pytorch 1.9.0

Dependencies

• Check the required python packages in requirements.txt.
• ffmpeg
• MPI-IS/mesh

Data

VOCASET

Request the VOCASET data from https://voca.is.tue.mpg.de/. Place the downloaded files data_verts.npy, raw_audio_fixed.pkl, templates.pkl and subj_seq_to_idx.pkl in the folder VOCASET. Download "FLAME_sample.ply" from voca and put it in VOCASET/templates.

BIWI

Request the BIWI dataset from Biwi 3D Audiovisual Corpus of Affective Communication. The dataset contains the following subfolders:

• 'faces' contains the binary (.vl) files for the tracked facial geometries.
• 'rigid_scans' contains the templates stored as .obj files.
• 'audio' contains audio signals stored as .wav files.

Place the folders 'faces' and 'rigid_scans' in BIWI and place the wav files in BIWI/wav.

Demo

Download the pretrained models from biwi.pth and vocaset.pth. Put the pretrained models under BIWI and VOCASET folders, respectively. Given the audio signal,

• to animate a mesh in BIWI topology, run:

  python demo.py --model_name biwi --wav_path "demo/wav/test.wav" --dataset BIWI --vertice_dim 70110  --feature_dim 128 --period 25 --fps 25 --train_subjects "F2 F3 F4 M3 M4 M5" --test_subjects "F1 F5 F6 F7 F8 M1 M2 M6" --condition M3 --subject M1
  

• to animate a mesh in FLAME topology, run:

  python demo.py --model_name vocaset --wav_path "demo/wav/test.wav" --dataset vocaset --vertice_dim 15069 --feature_dim 64 --period 30  --fps 30  --train_subjects "FaceTalk_170728_03272_TA FaceTalk_170904_00128_TA FaceTalk_170725_00137_TA FaceTalk_170915_00223_TA FaceTalk_170811_03274_TA FaceTalk_170913_03279_TA FaceTalk_170904_03276_TA FaceTalk_170912_03278_TA" --test_subjects "FaceTalk_170809_00138_TA FaceTalk_170731_00024_TA" --condition FaceTalk_170913_03279_TA --subject FaceTalk_170809_00138_TA
  

  This script will automatically generate the rendered videos in the demo/output folder. You can also put your own test audio file (.wav format) under the demo/wav folder and specify the argument --wav_path "demo/wav/test.wav" accordingly.

Training and Testing on VOCASET

Data Preparation

• Read the vertices/audio data and convert them to .npy/.wav files stored in vocaset/vertices_npy and vocaset/wav:

  cd VOCASET
  python process_voca_data.py
  

Training and Testing

• To train the model on VOCASET and obtain the results on the testing set, run:

  python main.py --dataset vocaset --vertice_dim 15069 --feature_dim 64 --period 30 --train_subjects "FaceTalk_170728_03272_TA FaceTalk_170904_00128_TA FaceTalk_170725_00137_TA FaceTalk_170915_00223_TA FaceTalk_170811_03274_TA FaceTalk_170913_03279_TA FaceTalk_170904_03276_TA FaceTalk_170912_03278_TA" --val_subjects "FaceTalk_170811_03275_TA FaceTalk_170908_03277_TA" --test_subjects "FaceTalk_170809_00138_TA FaceTalk_170731_00024_TA"
  

  The results and the trained models will be saved to vocaset/result and vocaset/save.

Visualization

• To visualize the results, run:

  python render.py --dataset vocaset --vertice_dim 15069 --fps 30
  

  You can find the outputs in the vocaset/output folder.

Training and Testing on BIWI

Data Preparation

• (to do) Read the geometry data and convert them to .npy files stored in BIWI/vertices_npy.

Training and Testing

• To train the model on BIWI and obtain the results on testing set, run:

  python main.py --dataset BIWI --vertice_dim 70110 --feature_dim 128 --period 25 --train_subjects "F2 F3 F4 M3 M4 M5" --val_subjects "F2 F3 F4 M3 M4 M5" --test_subjects "F1 F5 F6 F7 F8 M1 M2 M6"
  

  The results will be available in the BIWI/result folder. The trained models will be saved in the BIWI/save folder.

Visualization

• To visualize the results, run:

  python render.py --dataset BIWI --vertice_dim 70110 --fps 25
  

  The rendered videos will be available in the BIWI/output folder.

Using Your Own Dataset

Data Preparation

• Create the dataset directory <dataset_dir> in FaceFormer directory.

• Place your vertices data (.npy format) and audio data (.wav format) in <dataset_dir>/vertices_npy and <dataset_dir>/wav folders, respectively.

• Save the templates of all subjects to a templates.pkl file and put it in <dataset_dir>, as done for BIWI and vocaset. Export an arbitary template to .ply format and put it in <dataset_dir>/templates/.

Training and Testing

• Create the train, val and test splits by specifying the arguments --train_subjects, --val_subjects and --test_subjects in main.py.

• Train a FaceFormer model on your own dataset by specifying the arguments --dataset and --vertice_dim (number of vertices in your mesh * 3) in main.py. You might need to adjust --feature_dim and --period to your dataset. Run main.py.

• The results and models will be saved to <dataset_dir>/result and <dataset_dir>/save.

Visualization

• Specify the arguments --dataset, --vertice_dim and --fps in render.py. Run render.py to visualize the results. The rendered videos will be saved to <dataset_dir>/output.
