Claim 1:
2. The method of claim 1, wherein the generating of chroma prediction samples of the current coding block based on the chroma intra prediction mode comprises:
in response to a determination that the chroma intra prediction mode of the current coding block is the same as the matrix-based intra prediction mode derived as the luma intra prediction mode of the current coding block,
deriving an input boundary vector using neighboring chroma samples adjacent to the current coding block based on the width and height of the current coding block,
generating chroma prediction samples for the current coding block, based on matrix-vector multiplication between the input boundary vector and a matrix predefined for the matrix-based intra prediction mode; and
deriving a chroma prediction block for the current coding block based on the chroma prediction samples.
