Complexity Reduction Methods for Fractal Image Compression

Fractal image compression allows fast decoding but suffers from long encoding times. During the encoding a large number of sequential searches through a list of domains (portions of the image) are carried out while trying to find a best match for another image portion called range. In this article we review and extend the methods that have been developed to reduce the time complexity of this searching. Also we present a new taxonomy of the methods, provide an evaluation and propose two new techniques.
