Abstract
Disclosed in embodiments of the present application are an inter-frame prediction method, an encoder, a decoder, and a computer storage medium. The method comprises: a decoder parsing a code stream to obtain a prediction mode parameter of the current block; if the prediction mode parameter indicates that an inter-prediction value of the current block is determined using an inter-frame prediction mode, determining a first motion vector of a sub-block of the current block, wherein the current block comprises a plurality of sub-blocks; determining, on the basis of the first motion vector, a first prediction value of the sub-block and a motion vector deviation between a pixel position and the sub-block, wherein the pixel position is the position of a pixel within the sub-block; determining a filter coefficient of a two-dimensional filter according to the motion vector deviation, wherein the two-dimensional filter is used for performing secondary prediction processing according to a preset shape; and determining a second prediction value of the sub-block on the basis of the filter coefficient and the first prediction value, and determining the second prediction value as an inter-frame prediction value of the sub-block.
