POINT CLOUD DECODING METHOD, DECODER, AND NON-TRANSITORY COMPUTER-READABLE STORAGE MEDIUM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18228047 titled 'POINT CLOUD DECODING METHOD, DECODER, AND NON-TRANSITORY COMPUTER-READABLE STORAGE MEDIUM

Simplified Explanation

The patent application describes a method for decoding point cloud data.

  • The decoder decodes a bitstream and determines a mode parameter.
  • If the mode parameter indicates spatial scalability mode, the decoder calculates geometric center coordinates for the current node and its neighboring nodes.
  • The decoder determines local spatial coordinate means for the current node based on the geometric center coordinates.
  • The decoder then determines reconstructed geometric information for the current node based on the local spatial coordinate means.
  • The patent also includes a decoder and a computer-readable storage medium.


Original Abstract Submitted

A point cloud decoding method includes that: a decoder decodes a bitstream, and determines a mode parameter; in response to the mode parameter indicating to use a spatial scalability mode, the decoder determines geometric center coordinates of a current node, and determines, in the point cloud, geometric center coordinates of neighbouring nodes of the current node based on the geometric center coordinates of the current mode; the decoder determines local spatial coordinate means corresponding to the current node based on the geometric center coordinates of the current node and the geometric center coordinates of the neighbouring nodes; and the decoder determines reconstructed geometric information of the current node based on the local spatial coordinate means. Further, a decoder and a non-transitory computer-readable storage medium are also provided.
