Abstract
A method for intra prediction includes: 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; determining an occupancy number corresponding to the second number of neighboring nodes based on the occupancy information of the second number of neighboring nodes; and determining an occupancy prediction result of the child node of the coded node based on the occupancy number. A decoder and a method for intra prediction performed by the decoder are also provided.
