Abstract: This paper presents an advancement in Generative Face Video Compression (GFVC) recognized through contributions in recent JVET meetings. We optimized the general framework of GFVC by eliminating the need for an analysis model at the decoder side, and encoding the feature into bitstream at the encoder instead, which reduces the ...

We optimize the implemention codes of three representative GFVC works, i.e., FOMM, CFTE and FV2V, and further provide the unified codes regarding the encoder and decoder processes. Current extensions to the original code include DAC and HDAC

2024年12月18日 · This paper proposes a Generative Face Video Compression (GFVC) approach using Supplemental Enhancement Information (SEI), where a series of compact spatial and temporal representations of a face video signal (i.e., 2D/3D key-points, facial semantics and compact features) can be coded using SEI message and inserted into the coded video bitstream.

2024年3月22日 · Abstract: Generative face video coding (GFVC) can achieve high-quality visual face communication at ultra-low bit-rate ranges via strong facial prior learning and realistic generation. However, different kinds of feature representations hinder the interoperability of GFVC, as the bitstream generated from one type of feature representation can ...
