Abstract: A video conferencing framework based on face restoration uses information such as pose and expressions instead of using information from different source frames and driving frames. In an embodiment, this information comes from the current target frame. In another embodiment, the proposed system uses a discrete codebook-based representation comprising a generic branch that generates and transmits an integer vector indicating the indices of codewords, from which the decoder retrieves a rich high-quality codebook-based feature based on the same shared codebook with an encoder. An adaptive branch optionally provides additional detailed fidelity and expressive features using a low-quality low-bitrate downsized face input and further aggressively compressed. The low-quality feature is weighted and combined with the high-quality feature for final reconstruction.
