Abstract
An image or video processing method comprises receiving input data of a current block, mapping an MIP mode index to a default mode, and encoding or decoding the current block by referencing the default mode. Another image or video processing method comprises receiving input data of a current block coded or to be coded by an MIP mode, and parsing or signaling a transpose flag for the current block indicating whether transposing is applied in coding the current block. Reference samples of the current block are prepared from neighboring boundary samples according to the transpose flag. A matrix is selected to be multiplied to the reference samples to generate predicted samples. A transposing process is adaptively applied to the current block according to the transpose flag, and the predicted samples are used to encode or decode the current block.
