    Abstract: An adaptive image enhancement algorithm for region-based fractal image compression is proposed. By using an algorithm to determine which pixels have to be smoothed, then applying different smoothing filters for various image areas, the proposed algorithm can significantly eliminate the annoying blocking artifacts for images coded with low bit rate. The improved PSNR for coded 'Lena' image are roughly ranged from 0.37dB to 0.45dB for various image qualities.
