This repository contains the source code for the paper Beyond Keypoint Coding: Temporal Evolution Inference with Compact Feature Representation for Talking Face Video Compression by Bolin Chen, Zhao Wang, Binzhe Li, Rongqun Lin, Shiqi Wang, and Yan Ye.

The DCC keynote video presented by Dr. Yan Ye can be found in https://www.youtube.com/watch?v=7en3YYT1QfU.

The overall implementation codes and pretrained checkpoint can be found under following link: OneDrive.

We support python3. To install the dependencies run:

pip install -r requirements.txt

In addition, please activate the VVC codec run

sudo chmod -R 777 vtm

To train a model on VoxCeleb dataset, please follow the instruction from https://github.com/AliaksandrSiarohin/video-preprocessing.

When finishing the downloading and pre-processing the dataset, you can train the model,

python run.py

The code will create a folder in the log directory (each run will create a time-stamped new directory). Checkpoints will be saved to this folder. To check the loss values during training see log.txt. You can also check training data reconstructions in the train-vis subfolder. You can change the training settings in corresponding ./config/vox-256.yaml file.

To encode a sequence, please put the provided testing sequence in ./testing_data/ file and run

python Encoder.py

After obtaining the bistream, please run

python Decoder.py

For the testing sequence, it should be in the format of RGB:444 at the resolution of 256*256.

In ./evaluate/multiMetric.py file, we provide the corresponding quality measures, including DISTS, LPIPS, PSNR and SSIM.

The training code refers to the FOMM: https://github.com/AliaksandrSiarohin/first-order-model.

The arithmetic-coding refers to https://github.com/nayuki/Reference-arithmetic-coding.
