Krishna Chauhan, Anubhuti Khare . Review on Fractal Image Compression based on Fast DCT Algorithm. International Journal of Computer Applications. 97, 14 ( July 2014), 10-13. DOI=10.5120/17074-7512
Fractal image compressions is a lossy compression technique for digital images. It is based on the assumptions that the image redundancies can be efficiently exploited by means of block self-affine transformations . Unlike other compression techniques it considers the interrelations between local (range blocks) and global (domain blocks) data. Use of contractive transform on the space of images encompasses a wide variety of coding scheme. However, the high computational complexity of fractal image encoding greatly restricts its application. This review gives a study of different speed ups using DCT to reduce the searching time .
