Very fun reading .. I enjoyed lots of his other works too and works by other
LEGO modellers like f.x. the Alien on this page:

http://community-1.webtv.net/craigo-lego/scificraigolego/


Now that we are in too good geeky links that have something to do with
ascii-art, check this page :

http://www.ai.mit.edu/~jsd/Projects/ImagesToText/

Jeremy S. De Bonet is a student at MIT .. and one of the many complex projects
he have done is a image to text algorithm.
I think the edge tracing algorithm shows promised allthough you can tell from
it's output which uses a very basic set of characters that Jeremy is no
ascii-artist , but rather a skilled programmer.

I think that had he read my ascii-art tutorial, and in particular had he seen my
sun of directions ..

.. he would have had a better understanding of asciilines and could have made a
much better algoritm.

From a different point of view his algorithm is the only edgetracing image to
ascii algorithm i have seen , and is a good showcase of this approach - it also
proves that it was right when I first suggested to Markus that a edgetracer
would be a good idea.
I would certainly like to see how this edgetracer handles the
testsuite/competition at :
http://www.jave.de/image2ascii/competition2001/contributions.html

( BTW .. we really should submit some more contributions - It would be nice to
compare more tools ..
This may seem pointless at the time because people all seem to know that JavE
does the best conversions ( http://www.jave.de/ ) but stick with it .. the point
was not just to find the best converter but also to learn from each and improve
the tools )

Hmmm .. I'm going to CC this to Jeremy Bonet - maybe he will try his algorithm
on the testsuite or even better explain the algorithm in details or even show
some sourcecode

Check out rest of Jeremy's site btw .. in particular the Imagemosaics and the
stuff about texture synthesis was very interesting to me.

Hey Jeremy ! How about releasing some working tools for the public to download
and use ? Let the world gain from your research :)

Kind Regards
CeeJay
