Lines: 48 Hiya. About three weeks ago I asked for some references on Picture Compression algorithms using fractals. My thanks go to Evan Mills - University of Illinois at Urbana Mike Brindley - Oregon State University Rob Elliott - University of Illinois at Urbana Mark Adler - California Institute of Technology, Pasadena The references I received are :- Barnsley, M.F. "Fractals Everywhere" Barnsley, M.F. & Sloan, A.D. "A Better Way to Compress Images" January 1988 Byte Magazine pp. 215-223 Dewdney, A.K. "A Tour of the Mandelbrot Set Aboard the Mandelbus" February 1989 Scientific American pp. 88-91 The article by Dewdney in Scientific American is an introduction to fractals and the Mandelbrot set. It is easy to read and shows some striking examples of what can be produced by examination of the set. The article by Barnsley and Sloan in Byte Magazine is an introduction to a technique that they call Iterated Function Systems. The explanation of the technique is easy to follow and they even include a BASIC program to produce the Sierpinski Triangle. There are some very impressive examples of the outcome of the IFS technique especially the picture of the Bolivian girl. If anyone has a copy of the IFS transforms for the girl could they please send me a copy? Barnsley's book is a deeper treatment of IFS. I'm still in the middle of reading it so I wont say much except that it is been good so far! All these articles have references, some of which I'm chasing up. Thanks again to all who replied, Kev MERRY XMAS "I didn't say this! I wasn't here!" K.N.R.Conner@uk.ac.newcastle K.N.R.Conner@newcastle.ac.uk ...!ukc!newcastle.ac.uk!K.N.R.Conner
