SPECTRE: Visual Speech-Aware Perceptual 3D Facial Expression Reconstruction from Videos

Our method performs visual-speech aware 3D reconstruction so that speech perception from the original footage is preserved in the reconstructed talking head. On the left we include the word/phrase being said for each example.

This is the official Pytorch implementation of the paper:

Installation

Clone the repo and its submodules:

git clone --recurse-submodules -j4 https://github.com/filby89/spectre
cd spectre

You need to have installed a working version of Pytorch with Python 3.6 or higher and Pytorch 3D. You can use the following commands to create a working installation:

conda create -n "spectre" python=3.8
conda install -c pytorch pytorch=1.11.0 torchvision torchaudio # you might need to select cudatoolkit version here by adding e.g. cudatoolkit=11.3
conda install -c conda-forge -c fvcore fvcore iopath 
conda install pytorch3d -c pytorch3d
pip install -r requirements.txt # install the rest of the requirements

Installing a working setup of Pytorch3d with Pytorch can be a bit tricky. For development we used Pytorch3d 0.6.1 with Pytorch 1.10.0.

PyTorch3d 0.6.2 with pytorch 1.11.0 are also compatible.

Install the face_alignment and face_detection packages:

cd external/face_alignment
pip install -e .
cd ../face_detection
git lfs pull
pip install -e .
cd ../..

You may need to install git-lfs to run the above commands. More details

curl -s https://packagecloud.io/install/repositories/github/git-lfs/script.deb.sh | sudo bash
sudo apt-get install git-lfs

Download the FLAME model and the pretrained SPECTRE model:

pip install gdown
bash quick_install.sh

Demo

Samples are included in samples folder. You can run the demo by running

python demo.py --input samples/LRS3/0Fi83BHQsMA_00002.mp4 --audio

The audio flag extracts audio from the input video and puts it in the output shape video for visualization purposes (ffmpeg is required for video creation).

Training and Testing

In order to train the model you need to download the trainval and test sets of the LRS3 dataset. After downloading the dataset, run the following command to extract frames and audio from the videos (audio is not needed for training but it is nice for visualizing the result):

python utils/extract_frames_and_audio.py --dataset_path ./data/LRS3

After downloading and preprocessing the dataset, download the rest needed assets:

bash get_training_data.sh

This command downloads the original DECA pretrained model, the ResNet50 emotion recognition model provided by EMOCA, the pretrained lipreading model and detected landmarks for the videos of the LRS3 dataset provided by Visual_Speech_Recognition_for_Multiple_Languages.

Finally, you need to create a texture model using the repository BFM_to_FLAME. Due to licencing reasons we are not allowed to share it to you.

Now, you can run the following command to train the model:

python main.py --output_dir logs --landmark 50 --relative_landmark 25 --lipread 2 --expression 0.5 --epochs 6 --LRS3_path data/LRS3 --LRS3_landmarks_path data/LRS3_landmarks

and then test it on the LRS3 dataset test set:

python main.py --test --output_dir logs --model_path logs/model.tar --LRS3_path data/LRS3 --LRS3_landmarks_path data/LRS3_landmarks

and run lipreading with AV-hubert:

# and run lipreading with our script
python utils/run_av_hubert.py --videos "logs/test_videos_000000/*_mouth.avi --LRS3_path data/LRS3"
