Title:
HIGH-LEVEL SYNTAX DESIGN FOR GEOMETRY-BASED POINT CLOUD COMPRESSION
Document Type and Number:
WIPO Patent Application WO/2021/207406
Kind Code:
A3
Abstract:
An example device for decoding point cloud data includes memory configured to store the point cloud data and one or more processors implemented in circuitry and coupled to the memory. The one or more processors are configured to determine dimensions of a region box and determine dimensions of a slice bounding box. The one or more processors are also configured to decode a slice of the point cloud data associated with the slice bounding box. The dimensions of the region box are constrained to not exceed the dimensions of the slice bounding box.
