FIELD: predictive coding and decoding

SUBSTANCE: invention relates to the field of predictive coding and decoding. A method for encoding and decoding is proposed and includes the following steps: if the characteristic information of the current block meets a special condition, the first reference block corresponding to the current block is determined based on the first initial motion vector of the current block, and the second reference block corresponding to the current block is determined based on the second the initial motion vector of the current block; adjusting the first and second source motion vectors according to the first pixel value of the first reference block and the second pixel value of the second reference block to obtain a first target motion vector corresponding to the first source motion vector and a second target motion vector corresponding to the second source motion vector; encoding or decoding the current block based on the first and second target motion vectors.

EFFECT: improvement of coding performance, in particular, prediction quality, prediction error.
