Abstract
Picture coding and decoding methods, an encoder, a decoder and a storage medium are provided. The encoder, before performing coding processing according to a matrix-based intra prediction (MIP) mode, sets initial right shift parameters corresponding to different sizes and different MIP mode numbers as an uniform offset parameter, the offset parameter indicating a number of right shifting bits of a predicted value, and when performing coding processing according to the MIP mode, performs coding processing according to the offset parameter. The decoder, before performing decoding processing according to an MIP mode, sets initial right shift parameters corresponding to different sizes and different MIP mode numbers as an uniform offset parameter, the offset parameter indicating a number of right shifting bits of a predicted value, and when performing decoding processing according to the MIP mode, performs decoding processing according to the offset parameter.
