SCALE FACTOR FOR QUANTIZATION PARAMETER VALUES IN GEOMETRY-BASED POINT CLOUD COMPRESSION

Abstract:

A G-PCC encoder and G-PCC decoder may quantize and scale, respectively, a position of a child node. The G-PCC encoder may control the precision of the quantization and scaling using a quantization parameter (QP) value and a parameter value k, wherein the parameter value k specifies a number of QP points per doubling of a scaling step size to be used at the G-PCC decoder.
