Tangtang Yi · Jisuanji gongcheng · 2008
Based on short-distance piecewise self-similarity of the image,this paper proposes a real coding based on Partheno genetic algorithm to solve the matching problem of fractal image coding.Aiming at the matching of Range blocks that contain edge,it employs a direction operator to pilot the individuals moving along the edge of image.Experimental result suggests that at the costs of almost unnoticeable degeneration of decoding image quality,the proposed algorithm can achieve the speed-up of 60 times as the baseline fractal algorithm with full search.
