The Fractal Transform

This presentation will consider practical issues relating to the implementation of the discrete fractal transform for the representation and compression of digital images. Special focus will be made on the question of fractal image magnification and resolution enhancement.

Michael Barnsley, Iterated Systems, Inc.

The Fractal Transform

This presentation will provide a general overview of fractal image compression. Start with ferns and the collage theorem, then on to the computer world and the discovery of the fractal transform, followed by the commercialization via Iterated Systems, Inc. into such multimedia products as Microsoft Encarta. The talk will conclude with a discussion of lossless fractal compression, and a vision for the future.
