/Mesh Decoding Device, Mesh Encoding Device, Mesh Decoding Method, And Non-transitory Computer-readable Medium
Abstract
A mesh decoding device 200 includes: an intra decoding unit 202B that decodes coordinates of a vertex and connectivity information in an intra frame from a bit stream of the intra frame; and an inter decoding unit 202E that decodes coordinates of a decoding target vertex by adding a motion vector decoded from a bit stream of an inter frame and coordinates of a vertex corresponding to the decoding target vertex in a reference frame. the number of submeshes can be different in each of the intra frames, and the number of submeshes can be different in each of the inter frames.
