Methods and equipment for encoding and decoding point clouds

Abstract

The invention relates to methods and apparatus for encoding and decoding point clouds, the point cloud encoding method as an example consisting of a step of determining that the residual values ​​for all except one component of the attribute of a point in the point cloud are equal to 0; Based on determining that the residual values ​​for all components except one component of an attribute are equal to 0, determining the value of a component by the magnitude of the residual value of one component of the attribute minus the offset; encoding the value of a component; and signaling the encoded value in the bit stream.
