This paper addresses to an improved SOM based fractal compression technique which is used to test the possibility of the fractal compression to medical imaging. The two newly proposed methods competes the standard fractal image compression algorithms. Since the proposed algorithm is regenerating feature rich portions of the images without any loss of information at that region, the perceptual quality of the image is found to be very good than that of the standard fractal image compression algorithm. SOM based model is used for improving the performance of the fractal coding scheme and also to reduce the encoding time.
