Title:
INTER-FRAME PREDICTION METHOD, DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/072049
Kind Code:
A1
Abstract:
Provided by an embodiment of the present disclosure are an inter-frame prediction method, a device and a storage medium, the method comprising: determining at least one reference encoded block that is spatially adjacent to a prediction unit to be processed of an encoding block to be processed; for each preset reference frame, determining a corresponding AMVP of the prediction unit to be processed under each reference frame respectively according to reference information of each reference encoded block; determining a target AMVP from among corresponding AMVPs of the prediction unit to be processed under each reference frame, and using the reference frame corresponding to the target AMVP as a candidate reference frame; comparing the candidate reference frame with a first reference frame, and if the candidate reference frame is different from the first reference frame, performing motion estimation for the prediction unit to be processed by means of the candidate reference frame and the first reference frame respectively; determining a target reference frame from among the candidate reference frame and the first reference frame according to a motion estimated encoding cost corresponding to the candidate reference frame and the first reference frame. The embodiment of the present disclosure may reduce the processing complexity of target reference frame selection and increase the efficiency of video coding.
