Title:
POINT CLOUD DECODING DEVICE, POINT CLOUD DECODING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/277128
Kind Code:
A1
Abstract:
A point cloud decoding device 200 according to the present invention is provided with: a geometric information reconstructing unit 2040 for reconstructing position information of a point cloud; an upsampling unit 2120 for upsampling the point cloud reconstructed by the geometric information reconstructing unit 2040; and a tree synthesizing unit 2020 for performing inter prediction with reference to the upsampled point cloud. The upsampling unit 2120 calculates an offset vector from the coordinates of each point in the reconstructed point cloud, and performs the upsampling using the offset vectors.
