I was wrong. Opencv is optimized for intel procesors but it works on any procesor. It would be great if opencv was implemented somehow within Gem. At least for the motion tracking stuff. Does anyone know how to get started. Does one have to know C well or can a complete C noob have a go at it. It would be great if implemented as pix objects. 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)?

I tried running it with a low res 400x300 clip and it still did the same thing. I am trying to get a game going using an FTIR setup. Here is a reference: http://cs.nyu.edu/~jhan/ftirsense/
Jeff Han, sweet reference of course.
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!
