1. A method for processing video data, the method comprising, for each of a plurality of source video frames: using pixels representing the source video frame and at least one temporally-adjacent video frame, generating a motion history map based upon frame-to-frame movement of at least one region in the source video frame and temporally-adjacent video frames; identifying at least one salient region in the source video frame based upon the motion history map and static image saliency data; determining weighting data for warping pixels corresponding to background regions of the source video frame differently than pixels corresponding to the at least one salient region in the source video frame; and using the weighting data, warping the pixels representing the source video frame to generate pixels representing a warped video frame.
