Hi Marco,
I haven't done any vision processing yet, but plan to get into it sometime this
summer. In the meantime, I've been casually scanning the web for related sites.
Here's one you may find useful:

Hi Reimer,
I've seen HALCON listed in
http://www.cs.cmu.edu/afs/cs/project/cil/ftp/html/vision.html
After checking Pong Suvan's software/dll's, I was going to check a couple
more site's, HALCON's included :)
Just downloaded (http://www.ccs.neu.edu/home/psksvp/download.htm) and
tested the apps done by Pong Suvan to test/use/demonstrate his DLL's.
WOW ! :)
Looks like it has potencial for the kind of real-time processing I want to
implement in my CyberMaster+VideoCam project.
...so, tonight, I'll check HALCON's site :)
Thxs.

Thank you very much ! I'll check it out ASAP.

And I'll visit your web site too, ehehe ;)

Hi :)
(recovering a "very" old lugnet.robotics thread about Robotic Vision
software for Mindstorms, predating the release of LEGO Vision Command)
I'm assuming that you're the same psksvp that made the Robotic Vision dll's
at
http://www.ccs.neu.edu/home/psksvp/
(Try making a search on "Robotic Vision" or "psksvp" on the lugnet.robotics
and you'll see how old these threads are :)
Sorry but I can't resist making this question, since I "saw" you on
lugnet.robotics.rcx.legos:
Did you, or are you planning on using your vision library with LEGO bots ?
If so, are you planning on releasing working example code of it ?
Thxs ! :)
mc.
PS: Oh, and thxs for http://www.ccs.neu.edu/home/psksvp/download.htm !

I have seen this program (NIH) at a workshop, and it was pretty incredible.
I checked on the PC version (Scion makes this) and it is very similar. It
says that it can measure (distances?) Could this be used as "vision" for a
robot? Could this be used to "tell" a robot where it is?
Lots of questions, and fairly excited about the future!
