Title:
DYNAMIC MESH CODING WITH SIMPLIFIED TOPOLOGY
Document Type and Number:
WIPO Patent Application WO/2023/129986
Kind Code:
A3
Abstract:
In some embodiments, a mesh encoder encodes a dynamic mesh with connectivity simplification. The encoder encodes geometry information of the dynamic mesh using a video encoder and then decode the encoded geometry information to generate reconstructed geometry information. The encoder further determines a face to be removed from connectivity information of the dynamic mesh that contains a vertex in the reconstructed geometry information and updates the connectivity information by removing the face. The encoder further updates, based on updating the connectivity images, attribute component images and mapping component images of the dynamic mesh. The encoder encodes the updated connectivity information, the updated attribute component images, and the updated mapping component images along with other information to generate a coded mesh bitstream for the dynamic mesh.
