PATCH GENERATION FOR DYNAMIC MESH CODING

An architecture includes new blocks that transform mesh connectivity to enable lossy compression. In addition, a method generates surface patches from meshes and preserves the overall aspect of the object, while generating patches for efficient encoding using the V3C standard. Triangles are joined together into connected components, and conditional projection of each triangle to the surface is performed to enforce connectivity at the projected surface. A new depth filtering algorithm is able to be used to improve compression performance. The new blocks added for connectivity compression and the techniques introduced to ensure 2D connectivity to allow for UV texture map transmission and to filter depth values and avoid highfrequency edges in the depth image are described herein.
