In the January 1993 issue of BOARDWATCH magazine, there is an
ad for Fracterm BBS front-end software. Its claim to fame is 
that is supports fractal image compression, and you can download 
and display an svga image in 10-15 seconds, as a function of the
front end software. This allows you to browse GIFs visually online, 
and select your downloads from the images themselves, not just
text descriptions. 

IMHO, fractal compression blows away JPEG in every aspect. Even at 
it's most lossy, a fractally compressed images takes on a 'water color'
look. Jpeg simply gets less and less recognizable. Also, JPEG is a 
relatively mature (read, maxxed out) technology, whereas Fractal
compression has yet to reach it's potential.

One of the amazing aspects of fractal compression is that the 
decompression is resolution independant. A 100x100 gif can be
displayed at 320x200 without pixelization (blockiness). 

Anyway...you can check out FRACTERM at 604-734-5800 USR DS, 
or voice 800-676-3111. I am in no way connected with Fracterm. 

Although I thought the current incarnation of Fracterm was a little
lacking in functionality (as far as a BBS front end goes), I can see
it's potential, and I really hope it's fractal based technology
catches on.

Have fun!

Actually, that was in there as well quite a number of months ago. How it works
is interesting. In order to compress the image, they use a plug-in card with
a processor on it running some compression software. As I remember, the card
was a little on the expensive side. But, once the image was compressed into
a fractal image, it could be viewed by anyone with little processor load.
It looked to be quite impressive, actually.

Wait a minute...
If the original image is 100x100, then to 200x200 image the
edges or such must be estimated -- but can do it independently to
jpg or any image.

Even you saw details in 200x200 fractal compressed image, the
actual image may not contain those details.

But because fractal system (IFS) simulates real objects (like tree)
appropriately, you may get just simulated details to image.

So, what is the current method to make fractal compression?
Does it use collage theorem (i.e. ready made simulated objects or
such).
