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.
Claims10
A method of decoding point cloud data, the method comprising:
- determining dimensions of a region box, the region box identifying a region of a slice of the point cloud data;
- determining dimensions of a slice bounding box for the slice, wherein the slice bounding box and the region box are different and the dimensions of the region box are constrained to not exceed the dimensions of the slice bounding box;
- decoding the slice based on the dimensions of the region box and the dimensions of the slice bounding box;
- and
- parsing an attribute slice header syntax element indicative of an attribute parameter set identifier, wherein a value of the attribute slice header syntax element is restricted to be in a range of 0 to 15 inclusive, and wherein decoding the point cloud data is based on an attribute parameter set identified by the attribute parameter set identifier.
