摘要:
A method for coding view-dependent texture attributes of points in a 3D point cloud prior to transmission and decoding includes creating a supplemental enhancement information (SIE) message for the 3D point cloud prior to transmission and decoding. The SEI message includes parameters related to texture attributes of individual points in the 3D point cloud for a plurality of viewing states at an initial time, such that when the SIE message is received at a decoder, the decoder is enabled to use the message to classify the texture attributes and apply one or more texture attributes to individual points such that the texture of each individual point in the decoded 3D point cloud is a correct representation of texture of that individual point in the 3D point cloud prior to transmission and decoding for each of the viewing states.
