Fractal Image Compression Techniques
نویسندگان
چکیده
Image compression is an essential technology in multimedia and digital communication fields. Fractal image compression is a potential image compression scheme due to its potential high compression ratio, fast decompression and multi resolution properties. Fractal image compression utilizes the existence of self symmetry of images. Since Bransley gave the concept of fractal image compression in 1988, fractal image compression has obtained recognition and has become one of the most popular coding methods in the recent years. However the high computational complexity of fractal image encoding greatly restricts its applications. Several techniques and improvements have been suggested to speed up the fractal image compression. This paper presents a review of the techniques published for faster fractal image compression.
