INTERFRAME PREDICTION METHODS, ENCODERS, DECODERS, AND STORAGE MEDIA

Abstract

The invention relates to a method for interframe prediction, an encoder, a decoder, and a storage medium. The method includes: receiving a code stream and analyzing the code stream to obtain an identification element that provides illumination compensation, current motion information, and current prediction method; if the identification element containing illumination compensation is valid, the identification element using illumination compensation is obtained from the code stream; if the identification element using illumination compensation is valid, the index information of the target illumination compensation method is obtained from the code stream; and performing interframe prediction on the current block based on the index information of the target illumination compensation method, current prediction method, and current motion information, to obtain the prediction value.
