Abstract
A video decoding method includes decoding an image bitstream associated with a video sequence to obtain a reconstructed key frame; extracting features of the reconstructed key frame; decoding a feature bitstream associated with the video sequence to obtain a motion token; reconstructing a dense motion based on the features of the reconstructed key frame and the motion token; and generating video content based on the reconstructed dense motion.
