Speed Up Technique for Fractal Image Compression

Fractal Image compression is a novel technique in the field of image compression; it is based on affine contractive transforms and utilizes the existence of self-symmetry in the image. This technique has grabbed much attention in recent years because of manifold advantages, very high compression ratio, high decompression speed, high bit-rate and resolution independence. Since 1990 a lot of techniques and improvements have been published in this field. This review represents survey of most significant advances in the field of fractal image compression.
