Encoding method, decoding method, code stream, encoder, decoder and storage medium

Abstract

Disclosed in the embodiments of the present application are an encoding method, a decoding method, a code stream, an encoder, a decoder and a storage medium. The decoding method comprises: parsing a code stream, and determining a value of first syntax element identification information; when the first syntax element identification information indicates that the current block is allowed to use a preset selection network model to perform model selection, determining the preset selection network model of the current block, and according to the preset selection network model, determining a loop filtering network model used by the current block; and performing filtering processing on the current block by using the loop filtering network model, so as to obtain a reconstructed image block of the current block.
