Title:
METHOD AND APPARATUS FOR TALKING FACE VIDEO COMPRESSION
Document Type and Number:
WIPO Patent Application WO/2024/083100
Kind Code:
A1
Abstract:
Methods and apparatuses are provided for processing video data. An exemplary method includes: decompressing a compressed frame to generate a key frame representing a face; generating, for the key frame, a first set of parameters associated with a 3-dimensional (3D) face representation of the face; reconstructing, for each of one or more inter frames, a second set of parameters associated with a 3D face representation of the face according to compressed inter-predicted residuals of the second set of parameters; and generating a video comprising the face based on the key frame, the first set of parameters, and the second set of parameters.
