Claim 13:
14. A decoder, comprising: a second processor, a second memory configured to store instructions executable by the second processor, a second communication interface, and a second bus configured to connect the second processor, the second memory and the second communication interface, wherein the second processor is configured to, when executing the instructions, perform steps of:
decoding a bitstream to obtain a size, a coding mode, and residuals of a current block;
determining a first offset for calculating a second offset
when the coding mode of the current block is a Matrix-based Intra Prediction (MIP) mode, calculating the second offset based on the size of the current block, theft first offset and reconstructed values of adjacent pixels corresponding to the current block;
determining a first prediction value of the current block according to the second offset; and
determining a reconstructed value of the current block based on the first prediction value.
