OCCUPANCY CODING USING INTER PREDICTION WITH OCTREE OCCUPANCY CODING BASED ON DYNAMIC OPTIMAL BINARY CODER WITH UPDATE ON THE FLY (OBUF) IN GEOMETRY-BASED POINT CLOUD COMPRESSION - A simplified explanation of the abstract

  • This abstract for appeared for US patent application number 18300023 Titled 'OCCUPANCY CODING USING INTER PREDICTION WITH OCTREE OCCUPANCY CODING BASED ON DYNAMIC OPTIMAL BINARY CODER WITH UPDATE ON THE FLY (OBUF) IN GEOMETRY-BASED POINT CLOUD COMPRESSION'

Simplified Explanation

The abstract describes a coding technique called G-PCC (Geometry-based Point Cloud Compression) that is used to compress point cloud data. In this technique, the coder analyzes the occupancy of a child node within a reference node in a reference frame of the point cloud data. This information is then used to determine the context for decoding the occupancy bit of a child node in the current frame. Finally, arithmetic decoding is applied to decode the occupancy bit using the determined context.


Original Abstract Submitted

A G-PCC coder may determine an occupancy of a reference child node in a reference node, wherein the reference node is in a reference frame of point cloud data used for inter prediction of a current node in a current frame of the point cloud data. The G-PCC coder may further determine a context for decoding a current occupancy bit of a current child node of the current node based on the occupancy of the reference child node, and arithmetic decode the current occupancy bit using the context.
