The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: Disclosed in the present application are a coding method, a decoding method, a coder, a decoder and a storage medium. No matter at a coding end or a decoding end, the coding/decoding method comprises: according to a first intra-frame prediction mode, determining a first intra-frame prediction value of a target sub-block in a current block; on the basis of a reference sample value of the target sub-block, determining a second intra-frame prediction mode of the target sub-block; according to the second intra-frame prediction mode, determining a second intra-frame prediction value of the target sub-block; and, on the basis of the first intra-frame prediction value and the second intra-frame prediction value, determining an intra-frame prediction value of the target sub-block. Thus, when the current block uses an intra-frame sub-block partition mode, the present application fully utilizes content characteristics of a reconstructed area to adaptively select the second intra-frame prediction mode, and takes into account the first intra-frame prediction mode to perform combined prediction on the sub-blocks, thereby improving prediction accuracy of the intra-frame sub-block partition mode, and further improving coding and decoding performance.
