1. A method for intra prediction, applied to an encoder, comprising:
enabling intra prediction, and determining occupation information of a first number of neighbouring nodes of a current node;
determining occupation information of a second number of neighbouring nodes from the occupation information of the first 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 first number being greater than the second number, 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.
