METHODS AND DEVICES FOR BINARY ENTROPY CODING OF POINTS CLOUDS
摘要:
Methods and devices for encoding or decoding a point cloud. A bit sequence signalling an occupancy pattern for sub-volumes of a volume is coded using entropy coding. For a current sub-volume, probabilities of respective entropy coders for entropy coding the occupancy pattern may be selected based on occupancy data for a plurality of neighbouring sub-volumes of the current sub-volume and on occupancy data for subdivisions of the neighbouring sub-volumes.
