Abstract
Apparatuses and methods are disclosed for encoding and for decoding mesh data. Disclosed encoding techniques include receiving a mesh sequence, including geometry data of vertices of meshes in the sequence and coding motion data into a bitstream of coded mesh data. The motion data coding comprises transforming, based on a Graph Fourier Transform (GFT), the geometry data to obtain GFT coefficients representative of the motion data, and then coding the GFT coefficients into the bitstream. Disclosed decoding techniques include receiving a bitstream of coded mesh data, including coded motion data and decoding the motion data from the bitstream. The decoding of the motion data comprises decoding GFT coefficients representative of the motion data, and then inverse transforming, based on the GFT, the decoded GFT coefficients to obtain decoded geometry data of vertices of meshes in the sequence.
