After checking Pong Suvan's apps/lib (http://www.ccs.neu.edu/home/psksvp/),
I checked HALCON 5.2 (http://www.mvtec.com/), as was my intention.
HALCON looks like a very powerfull, well documented, well done and easy to
use (through HDeveloper and/or the COM version) software package.
Now, correct me if I'm wrong, but it has two disadvantages:
1) It looks like a *commercial* oriented package, well beyond my home Lego
robotic vision project. :(
2) It doesn't support general Video for Windows video cards/frame grabbers,
only specific models of frame grabbers.
So, I'll keep searching for a while and if I can't find any good
alternative, I'll stick to freeware Pong Suvan's good solution.
Any suggestions, links, etc.. on this subject are welcome to help me in
this project.
thxs :)
