- This sounds like a filtered description of one of Iterated Systems Inc's
- demonstration images. They have a whole range of products by now, and
- a whole range of demo images. The reptile is one on which the zoom-in
- trick works nicely. Someone commented on this in another thread: you
- are of course conjuring up information if you zoom in further than the
- original definition. The additional data is manufactured through
- interpolation --- fractal interpolation in this case. If the original
- picture was highly self-similar, this procedure yields a remarkably
- convincing blow-up. Definitely better on the eye than growing square
- pixels, but no use if you want to read the number plate on that spy
- photograph of yours...
-
- The people doing the work are headed by Michael Barnsley,
- previously of Georgia Tech. They patented their algorithm,
- but a book on the techniques has just appeared (see the post
- on the new fractal image compression book).
