Constructing a list of highest probability modes for matrix-based intra prediction

摘要

Devices, systems and methods for digital video coding, including matrix-based intra prediction methods for video coding, are described. In a representative aspect, a method for video processing includes generating a list of highest probability modes (MPM) based on a rule, for transition between a current video block of the video and a coded representation of the current video block, the rule being the current video based on whether a neighboring video block of the block is coded in matrix-based intra prediction (MIP) mode, and performing a transition between the current video block and the coded representation of the current video block using the MPM list; The transition applies the non-MIP mode to the current video block, and the non-MIP mode is different from the MIP mode.
