Title:
MESH DECODING DEVICE, MESH ENCODING DEVICE, MESH DECODING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/014195
Kind Code:
A1
Abstract:
A displacement amount decoding unit 206 of a mesh decoding device 200 according to the present invention is provided with: a decoding part 206A that decodes a level value from a displacement amount bit stream; an inverse quantization part 206B that generates a transformation coefficient by inverse-quantizing the level value; an inverse wavelet transform part 206C that generates a predictive residue by executing inverse wavelet transform for the transformation coefficient; and an adder 206D that calculates a displacement amount by adding together a predicted displacement amount and the predictive residue.
