| 摘要 |
Embodiments of the present invention provide a video encoding method and decoding method and apparatuses, which are applied to the field of signal processing, and can enhance video decoding performance, and improve decoding precision. The video decoding method, applied to a decoder end, includes: acquiring N pieces of motion information of a target area according to motion-related information in a bitstream generated by an encoder end, 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. The video encoding method and decoding method and the apparatuses provided in the embodiments of the present invention are used for video encoding and decoding. |
