Michael Fielding Barnsley is a British
mathematician
, researcher and an entrepreneur
who has worked on fractal compression
; he holds several patent
s on the technology. He received his Ph.D in Theoretical Chemistry from University of Wisconsin–Madison
in 1972. In 1987 he founded Iterated Systems Incorporated, and in 1988 he published a book entitled Fractals Everywhere' and in 2006 'SuperFractals' .
He has also published these scientific papers: "Existence and Uniqueness of Orbital Measures", "Theory and Applications of Fractal Tops", "A Fractal Valued Random Iteration Algorithm and Fractal Hierarchy", "V-variable fractals and superfractals", "Fractal Transformations" and "Ergodic Theory, Fractal Tops and Colour Stealing".
He is also credited for discovering the Collage Theorem
.
Iterated Systems was initially devoted to fractal image compression
(epitomised by the Barnsley fern
), and later focused on image archive management and was renamed to MediaBin. It was acquired in 2003 by Interwoven
, by which time Barnsley was no longer affiliated with the company.
As of 2005, he is on the faculty of the Mathematical Sciences Institute of the Australian National University
. Barnsley held a previous faculty position at Georgia Tech
.

Fractal compression
Fractal compression is a lossy compression method for digital images, based on fractals. The method is best suited for textures and natural images, relying on the fact that parts of an image often resemble other parts of the same image...

He is also credited for discovering the Collage Theorem
Collage theorem
In mathematics, the collage theorem characterises an iterated function system whose attractor is close, relative to the Hausdorff metric, to a given set. The IFS described is composed of contractions whose images, as a collage or union when mapping the given set, are arbitrarily close to the given...
