Abstract
A mesh decoder reconstructs geometry information of a dynamic mesh from a coded mesh bitstream of the dynamic mesh. The reconstructed geometry information include data specifying vertices of the dynamic mesh. The decoder also reconstructs connectivity information of the dynamic mesh which includes data specifying faces of the dynamic mesh. The decoder refines the reconstructed connectivity information based on the reconstructed geometry information to generate refined connectivity information. The decoder further reconstructs an attribute image of the dynamic mesh from the coded mesh bitstream which includes image content to be applied to faces of the dynamic mesh. The decoder refines the reconstructed attribute image based on the reconstructed geometry information to generate refined attribute image. Based on the reconstructed geometry information, the refined connectivity information, and the refined attribute image, the decoder reconstructs the dynamic mesh which can be rendered for display.
