In a representative aspect, a method for video processing includes performing a conversion between a current video block of a video and a bitstream representation of the current video block using a matrix based intra prediction (MIP) mode in which a prediction block of the current video block is determined by performing, on reference boundary samples located to a left of the current video block and located to a top of the current video block, a boundary downsampling operation, followed by a matrix vector multiplication operation, and selectively followed by an upsampling operation, where instead of reduced boundary samples calculated from the reference boundary samples of the current video block in the boundary downsampling operation, the reference boundary samples are directly used for a prediction process in the upsampling operation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Matrix-based intra prediction using filtering","description":"Devices, systems and methods for digital video coding, which includes matrix-based intra prediction methods for video coding, are described.
