Claim 8:
9. A method for intra prediction, implemented by a decoder, the method comprising:
enabling intra prediction, and determining occupancy information of a first number of neighboring nodes of a coded node;
determining occupancy information of a second number of neighboring nodes of the coded node based on a position association between at least one neighboring node of the coded node and a child node of the coded node, wherein the first number is greater than the second number;
determining an occupancy number corresponding to the second number of neighboring nodes based on the occupancy information of the second number of neighboring nodes;
obtaining a third number associated with the second number; and
performing intra prediction on occupancy information of the child node of the coded node based on the occupancy number and the third number to derive an occupancy prediction result of the child node of the coded node.
