Video Encoding Method and Decoding Method and Apparatuses

摘要

A video decoding method includes acquiring N pieces of motion information of a target area according to motion-related information in a bitstream, where N is an integer greater than or equal to 2, separately performing a motion compensation operation on the target area by using each piece of motion information in the N pieces of motion information to obtain N predictions of the target area, where each prediction in the N predictions of the target area includes predicted values of all sampling points in the target area, acquiring a prediction selection reference of the target area, where the prediction selection reference of the target area is values of all sampling points in a corresponding reference area of the target area, and determining a final prediction of the target area according to the N predictions of the target area and the prediction selection reference of the target area.

1. A video decoding method, which is applied to a decoder end, comprising:
acquiring N pieces of motion information of a target area according to motion-related information in a bitstream generated by an encoder end, wherein N is an integer greater than or equal to 2; performing a motion compensation operation on the target area separately by using each piece of motion information in the N pieces of motion information to obtain N predictions of the target area, wherein each prediction in the N predictions of the target area comprises predicted values of all sampling points in the target area; acquiring a prediction selection reference of the target area, wherein the prediction selection reference of the target area comprises values of all the sampling points in a corresponding reference area of the target area; and determining a final prediction of the target area according to the N predictions of the target area and the prediction selection reference of the target area.
