Abstract
A decoder decodes, from a bitstream, a quantized wavelet coefficient representing a displacement of a vertex in a set of vertices of a three-dimensional (3D) mesh and decodes from the bitstream, quantization information indicating a quantization offset associated with a subset of vertices of the set of vertices. The decoder further inverse quantizes the quantized wavelet coefficient to determine a wavelet coefficient and adjusts, based on the vertex being in the subset, the wavelet coefficient according to the quantization offset to determine the displacement of the vertex.
