Abstract

A decoding method is provided. A bitstream is decoded to determine a prediction mode parameter. The bitstream is decoded to determine a matrix-based intra prediction (MIP) parameter of a current block, in response to the prediction mode parameter indicating that MIP is used to determine an intra prediction value. The bitstream is decoded to determine transform coefficients of the current block and a low-frequency non-separable transform (LFNST) index of the current block. A mapping mode of an LFNST transform set is determined according to the MIP parameter, in response to the LFNST index indicating that an LFNST is used for the current block. According to the mapping mode of the LFNST transform set, one LFNST transform kernel candidate set is selected from a plurality of LFNST transform kernel candidate sets, and an LFNST transform kernel used for the current block is determined from the selected LFNST transform kernel candidate set.
