DYNAMIC MESH COMPRESSION METHOD AND DEVICE

WIPO Patent Application WO/2024/058614

A1

A mesh compression method and device, according to an embodiment of the present invention, may reconstruct a base mesh on the basis of geometry information obtained from a base mesh bitstream, perform surface division on the reconstructed base mesh, obtain a displacement vector for at least one of a vertex of the reconstructed base mesh and a sub-vertex generated by the surface division, reconstruct an enhancement mesh on the basis of the reconstructed base mesh and the obtained displacement vector, and obtain a texture image associated with the surface of the reconstructed enhancement mesh.
