ALEXANDRIA, Va., Aug. 12 -- United States Patent no. 12,705,800, issued on Aug. 11, was assigned to TENCENT AMERICA LLC (Palo Alto, Calif.).
"Quantization in mesh compression" was invented by Jun Tian (Belle Mead, N.J.), Xiaozhong Xu (Shenzhen, China) and Shan Liu (San Jose, Calif.).
According to the abstract* released by the U.S. Patent & Trademark Office: "In a method, a base mesh includes a subset of a plurality of vertices of a mesh. A position prediction of a current vertex of the base mesh is determined. A motion field prediction of the current vertex of the base mesh is determined. A position prediction residue for the position prediction of the current vertex is determined based on a first quantization step value. A motion field p...
