I found a great looking set of vision libraries that might work: http://sourceforge.net/projects/vxl/ I dont have any programming skills but I'm going to poke around and see what I can do. I think that anyone with a little bit of C++ skills would be able to wrap the vcsl library within vxl to come up with a good computer vision/tracking set of objects. The question is how cpu efficient it will be? Alain

The buigest problem with opencv (a great option I believe) is that it only works on intell processors,
so
anyone on an amd or a ppc (like me) would be screwed. If there was something like that for all processors it would be awsome. I think this kind of computer vision framework is needed in PD, specially concidering how easy an FTIR setup is to build and the possibilities it could open. Alain

Of course the "obvious" solution is to port the OpenCV bits and pieces to PD/Gem externals :-) We did some last year for VVVV, using some
existing framework, it worked within one day or so.There are several vision/video external frameworks out there; are any of them in Gem or elsewhere in PD (pdp, gridflow, etc)?

pix_mutiblob is way to slow, I cant get gridflow compiled, and
pidip is not working currently on the extended version. Is there another
option to do functional multitracking on a mac with pure data? I really cant
fork over the dough for max/msp/jitter, but there is a free jitter plugin
called cv.jit that looks great: http://www.iamas.ac.jp/~jovan02/cv/ Is there a posibility that anyone will port this over to PD I wonder?I dunno if this will happen or if it is possible to port directly from Jitter to Pd (maybe Gridflow or PDP/PIDIP?), but I think we could all benefit with some super DSP-geek "keeping up with the Joneses" on many fronts!
