==METHOD AND APPARATUS OF ENCODING/DECODING POINT CLOUD GEOMETRY DATA USING AZIMUTHAL CODING MODE - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18553786 titled 'METHOD AND APPARATUS OF ENCODING/DECODING POINT CLOUD GEOMETRY DATA USING AZIMUTHAL CODING MODE

The abstract describes a method for encoding a point cloud into a bitstream of encoded point cloud data representing a physical object. The method involves an azimuthal coding mode that provides a series of bits for encoding a coordinate of a point in the point cloud. 

* Dividing a parent interval into left and right half intervals
* Interpolating angles associated with the left and right half intervals from inherited angles of the parent interval
* Selecting a context based on the interpolated angles
* Context-adaptive binary entropy encoding of a bit into the bitstream based on the selected context, indicating the half interval to which the point coordinate belongs

==Original Abstract Submitted==

A method of encoding a point cloud into a bitstream of encoded point cloud data representing a physical object is provided. The method includes an azimuthal coding mode providing a series of bits for encoding a coordinate of a point of the point cloud. The method includes: dividing a parent interval, to which the point coordinate belongs to, into a left half interval and a right half interval; interpolating a left angle (φ), associated with the left half interval, and a right angle (φ), associated with the right half interval, from at least one inherited angle associated with the parent interval; selecting a context depending on the left angle (φ) and the right angle (φ); and context-adaptive binary entropy encoding a bit (b), into the bitstream, based on the selected context, the coded bit (b) indicating which of the two half intervals the point coordinate belongs to.
