Abstract
Embodiments of the present disclosure disclose a decoding method. The method includes: determining planar structure information of neighborhood nodes of a current node; determining context indication information of the current node according to the planar structure information of the neighborhood nodes; determining target context information according to the context indication information; and decoding a bitstream based on the target context information to determine planar position information of the current node.
Claims20
A decoding method, applied to a decoder and comprising:
- determining planar structure information of neighborhood nodes of a current node;
- determining context indication information of the current node according to the planar structure information of the neighborhood nodes;
- determining target context information according to the context indication information;
- and
- decoding a bitstream based on the target context information to determine planar position information of the current node.
An encoding method, applied to an encoder and comprising:
- determining planar structure information of neighborhood nodes of a current node;
- determining context indication information of the current node according to the planar structure information of the neighborhood nodes;
- determining target context information according to the context indication information;
- determining planar position information of the current node;
- and
- encoding the planar position information of the current node based on the target context information, and signalling obtained encoded bits into a bitstream.
A computer-readable storage medium, having a computer program and a bitstream stored thereon, wherein the computer program, when executed by a processor, enables the processor to perform following steps to generate the bitstream:
- determining planar structure information of neighborhood nodes of a current node;
- determining context indication information of the current node according to the planar structure information of the neighborhood nodes;
- determining target context information according to the context indication information;
- determining planar position information of the current node;
- and
- encoding the planar position information of the current node based on the target context information, and signalling obtained encoded bits into the bitstream.
