SCALING OF QUANTIZATION PARAMETER VALUES IN GEOMETRY-BASED POINT CLOUD COMPRESSION (G-PCC)

Abstract:

A G-PCC coder is configured to receive the point cloud data, determine a final quantization parameter (QP) value for the point cloud data as a function of a node QP offset multiplied by a geometry QP multiplier, and code the point cloud data using the final QP value to create an coded point cloud.
