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 ..

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 ###### From: Markus Gebhard Newsgroups: alt.ascii-art Subject: Re: Physical ASCII mosaic Date: Sat, 26 Jan 2002 21:59:33 +0100 Organization: University of Karlsruhe, Germany Lines: 274 Message-ID: <3C5318B5.80F13461@rz.uni-karlsruhe.de> References: <3C51F913.2278A661@ericharshbarger.org> <3c52d8eb$0$14078$edfadb0f@dspool01.news.tele.dk> NNTP-Posting-Host: wn4-jarjar.wn4.uni-karlsruhe.de Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit X-Trace: news.rz.uni-karlsruhe.de 1012078710 5085 172.20.12.141 X-Complaints-To: usenet@rz.uni-karlsruhe.de X-Mailer: Mozilla 4.79 [en] (Win98; U) X-Accept-Language: en Path: chonsp.franklin.ch!pfaff.ethz.ch!news-zh.switch.ch!news.imp.ch!news.imp.ch!uni-erlangen.de!newsfeeds.belnet.be!news.belnet.be!feed.news.nacamar.de!rz.uni-karlsruhe.de!news.rz.uni-karlsruhe.de!not-for-mail Xref: chonsp.franklin.ch alt.ascii-art:27315 Hi CeeJay, CeeJay wrote: [...] > 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/ > 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.

Mh - but but but - I feel that the edge detect with a proper line algorithm would be quite nice for someone working in the `watermark' mode. I only tried once to use a greyscale-converted picture as a basis for a line picture and the work as well as the result were not promising (to say the least). A nice edge detect would make the copying from a bitmap image somewhat easier. And, apart from that, I don't think the examples you posted are `bad' images. They are good starting points I think.

They are good starting points I think. Ok, you are right about the watermark thing. Initially I meant that the algorithm itself is no good point to start from for writing a better algorithm.
