L-FRAMES WITH BOTH FILTERED AND UNFILTERED REGIONS FOR MOTION-COMPENSATED TEMPORAL FILTERING IN WAVELET-BASED CODING

摘要

The present invention is directed to a method and device for encoding video. According to the present invention, a first region in a first frame is matched to a second region in a second frame. A first partially encoded frame is produced including a difference between pixel values of the first and second region. A second partially encoded frame is produced including pixel values of either the first or second region. Further, the first and second partially encoded frame is transformed into wavelet coefficients.
