Method and device for intra prediction

A method for intra prediction, applied to a decoder, comprising:

• determining occupation information of a first number of neighbouring nodes of a current node, wherein the first number is 26;
• determining occupation information of a second number of neighbouring nodes of the current node according to a position relationship between at least one neighbouring node of the current node and a child node of the current node, the second number being 7, wherein the position relationship comprises that the at least one neighbouring node of the current node adjoins the child node of the current node by a face, edge or corner;
• and
• determining an occupation prediction result of the child node of the current node based on the occupation information of the first number of neighbouring nodes of the current node and the occupation information of the second number of neighbouring nodes.

A device for use in a decoder, the device comprises:

• a memory, configured to store executable intra prediction instructions;
• and
• a processor, configured to execute the executable intra prediction instructions stored in the memory to perform operations comprising:
• determining occupation information of a first number of neighbouring nodes of a current node, wherein the first number is 26;
• determining occupation information of a second number of neighbouring nodes of the current node according to a position relationship between at least one neighbouring node of the current node and a child node of the current node, the second number being 7, wherein the position relationship comprises that the at least one neighbouring node of the current node adjoins the child node of the current node by a face, edge or corner;
• and
• determining an occupation prediction result of the child node of the current node based on the occupation information of the first number of neighbouring nodes of the current node and the occupation information of the second number of neighbouring nodes.
