Abstract:
1. A method to post-process a non-key frame of a video sequence through a neighboring key frame of the video sequence, comprising: downsampling a reconstructed key frame to form a downsampled reconstructed key frame; upsampling the downsampled reconstructed key frame to form an upsampled reconstructed key frame; forming a difference between the reconstructed key frame and the upsampled reconstructed key frame; adding the difference to a reconstructed non-key frame to compensate the reconstructed non-key frame to form an edge enhanced non-key frame; and updating the edge enhanced non-key frame to form an updated non-key frame based on a difference between a downsampled edge enhanced non-key frame and a downsampled non-key frame, wherein the downsampled edge enhanced non-key frame is formed by downsampling the edge enhanced non-key frame and the reconstructed non-key frame is formed by upsampling the downsampled non-key frame.
