Abstract

See full text

Aspects of the disclosure provide methods, apparatuses, and a non-transitory computer-readable medium for point cloud compression and decompression. In a method, an octree partitioning structure for a bounding box of a point cloud is determined. Whether parallel encoding is to be performed on occupancy codes of nodes in a range of one or more partitioning depths in the octree partitioning structure is determined. The parallel encoding on the occupancy codes of the nodes is performed in response to the parallel encoding being determined to be performed on the occupancy codes of the nodes in the range of the one or more partitioning depths in the octree partitioning structure. A coded bitstream is generated based on the encoded occupancy codes of the nodes. The coded bitstream includes syntax information that indicates whether parallel decoding is to be performed on the occupancy codes of the nodes in the range.
