Abstract

Video coding using reduced-rank matrices for matrix intra prediction (MIP). In a video coding method, information is obtained indicating a matrix rank, k, and a matrix intra prediction mode for a current block. The current block has a block shape, and neighboring reference samples. Based on the intra prediction mode and the current block shape, a first and second matrix are selected from a stored set of intra prediction matrices. Each of the stored matrices is associated with a respective block shape and intra prediction mode. A first rank-k matrix is obtained from the first matrix, and a second rank-k matrix is obtained from the second matrix. The current block is then predicted using a product of the first rank-k matrix, the second rank-k matrix, and the reference samples.
