Abstract
A method for intra prediction includes: 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, where the first number is greater than the second number; and determining an occupancy prediction result of the child node of the coded node based on the occupancy information of the second number of neighboring nodes. An encoder for implementing the above method is also provided.
