INTER PREDICTION IN POINT CLOUD COMPRESSION - A simplified explanation of the abstract

  • This abstract for appeared for US patent application number 18304268 Titled 'INTER PREDICTION IN POINT CLOUD COMPRESSION'

Simplified Explanation

The abstract describes a device that can encode a point cloud, which is a collection of points in a three-dimensional space. The device has a memory to store the data of the point cloud and processors to perform certain tasks. It determines a residual value for each point in the point cloud, which can be either a radius residual or an azimuth residual. The device also determines a context for encoding the residual value based on whether the point is coded with intra prediction or inter prediction. Finally, it uses the determined context to encode the residual value using entropy encoding, a technique to compress data.


Original Abstract Submitted

A device for encoding a point cloud comprises a memory configured to store point cloud data for the point cloud; and one or more processors configured to: determine a residual value associated with a current point of the point cloud, the residual value associated with the current point being a radius residual or an azimuth residual; determine a context for entropy encoding the residual value based on whether the current point is coded with intra prediction or inter prediction; and entropy encode the residual value using the determined context.
