Abstract

Provided in the present application are a decoding method and apparatus, a coding method and apparatus, and devices. The decoding method comprises: decoding a code stream corresponding to the current image block, so as to obtain a coefficient hyper-parameter feature corresponding to the current image block; determining a probability distribution parameter on the basis of the coefficient hyper-parameter feature; on the basis of the probability distribution parameter, decoding a code stream corresponding to the current image block, so as to obtain an initial reconstruction feature corresponding to the current image block; and on the basis of the initial reconstruction feature, determining a target reconstructed image block corresponding to the current image block. By means of the technical solution of the present application, the coding performance and the decoding performance can be improved.
