Abstract
An intra prediction method and a decoder are provided. The method includes the following. Coordinate information of a current node and a current level corresponding to the current node are determined. A current quantity is determined based on the current level, where the current quantity is positively correlated with the current level. Current neighbour nodes are determined based on the coordinate information of the current node, where the current neighbour nodes are neighbour nodes of the current quantity among neighbour nodes of a parent node of the current node. Intra prediction is performed on the current node based on the coordinate information of the current node and the current neighbour nodes.
