Fractal image compression is a lossy compression technique. Compression is performed by locating self-similar sections of an image, then using a fractal algorithm to generate the sections. Fractals are a very interesting field of study, but this page won’t attempt to cover everything there is to know about fractals. For the most part, we will only look at fractals as they relate to compression. To learn more about this fascinating subject, try looking into some of the resources pointed to by the Fractal FAQ

Genetic Algorithms for Fractal Image and Image Sequence Compression

In this paper we present a method that uses Genetic Algorithms (GAs) to find a Local Iterated Function System (LIFS) that encodes a single image. By doing this, the time needed to achieve this LIFS is reduced by about compared with Barnsley’s method if similar image quality is desired. If less quality is acceptable, using a GA we can vary the time the encoding will take by changing parameters such as population size and number of generations allowed.

Algorithm for Fast Fractal Image Compression

Fractal image compression is a promising new technology that may successfully provide a codec for PC-to-PC video communications. Unfortunately, the large amount of computation needed for the compression stage is a major obstacle that needs to be overcome. This paper introduces the Fast Fractal Image Compression algorithm, a new approach to breaking the “speed problem” that has plagued previous efforts.

Fractal Frequently Asked Questions and Answers

The Usenet newsgroup sci.fractals and the listserv forum frac-l are devoted to discussions on fractals. This FAQ (Frequently Asked Questions) is an electronic serial compiled from questions and answers contributed by many participants in those discussions. This FAQ also lists various archives of programs, images, and papers that can be accessed through the global computer networks (WWW/Internet/BITNET) by using email, anonymous ftp, gophers, and World Wide Web browsers. This FAQ is not intended as a general introduction to fractals, or a set of rigorous definitions, but rather a useful summary of ideas, sources, and references.

DCL user feedback: The links on that particular page are extremely outdated, as well as a lot of the information. It’s still useful, but there’s gotta be
a more up-to-date alternative

Fractal image compression based on delaunay triangulation

PhD thesis by Franck Davoine, 20 December 1995. The key to a good fractal compression algorithm is the method by which it breaks down segments of an image into smaller pieces, called partitioning. Davoine introduces a partitioning method based on Delaunay triangulation.
