Abstract
In this work, we propose and investigate techniques developed in the context of fractal image coding for generalizing block-matching algorithms as used in motion-compensated video codecs. By allowing a gray value adaptation (similar to non-iterative fractal techniques) within the block-matching process, we obtain MC error residuals with significantly lower entropy values as compared to pure block-matching. This leads to a significantly improved rate/distortion performance for video sequences with illumination changes or high motion content at a low computational cost.
