Abstract
Video coding using neural network based inter-frame prediction is performed by generating a current reference frame by generating intermediate flows based on two input frames, performing backward warping of the input frames to generate reconstruction frames, and generating a fusion map and a residual map based on the input frames, the intermediate flows and the reconstruction frames. The video coding method further includes outputting an enhanced frame or a virtual reference picture by generating a feature map with different levels, based on the current reference frame, a first reference frame and a second reference frame, generating a predicted frame based on aligned features from the generated feature map by refining the current reference frame, the first reference frame, and the second reference frame, generating a final residual based on the predicted frame, and computing the enhanced frame as an output by adding the final residual to the current reference frame.
