Patent ID: 8135073

Claim:
A method, comprising: receiving, at a decoder, a video stream containing encoded frame based video information including an encoded first frame and an encoded second frame, the encoding of the second frame depends on the encoding of the first frame, the encoding of the second frame includes motion vectors indicating differences in positions between regions of the second frame and corresponding regions of the first frame, the motion vectors define the correspondence between regions of the second frame and corresponding regions of the first frame; and via the decoder: decoding the first frame; determining a re-mapping strategy for video enhancement of the decoded first frame using a region-based analysis; re-mapping regions of the decoded first frame according to the determined video enhancement re-mapping strategy for the first frame so as to enhance the first frame; recovering from the video stream, the motion vectors for the second frame; decoding the second frame; and re-mapping regions of the second frame that correspond to regions of the first frame using the video enhancing re-mapping strategy for the first frame so as to enhance the second frame.
