survey on fractal image compression

the need for multimedia applications has increased over the years. due to this issue, image and video compression becoming an essential problem in reducing time and data storage. fractal image compression (fic) is a compression technique which results in loss, and we can have large amounts of compression. this scheme works by classifying an image into blocks and uses contractive mapping. some of fics advantages can be expressed as follows: comparing with other standard compression techniques, it has a good interchange between pnsr and compression ratio and it zooms the image without reducing the quality due to its resolution independent nature. the main fics drawback, is its complexity in encoding and lack of speed.
