Abstract
A computer-implemented method for learning-based bidirectional video compression includes, given a current frame, generating a single reference frame from the current frame and bidirectional frames by using a neural network, estimating a motion between the current frame and the reference frame, obtaining a reconstructed motion by inputting the motion to a motion encoder and decoder, generating a set of temporal contexts based on the reconstructed motion and propagated feature, and compressing the current frame based on the temporal contexts by an inverse channel-wise entropy model which is adapted to reconstruct the relationship among channels such that the channels with less entropy are coded first and the channels with larger entropy are coded with the help of the previously coded channels.
