Blob tracking/Colour tracking

AnneKristine's icon

Hi.
I am trying to figure out how to track objects in jitter.

I am faily new to jitter (have used max msp in general for around a year)

My case is that my group are working on a project where we are trying to track 3 white objects i a videoscreen. But however we have to filter everything else out than these 3 white objects.

Any idea or links to introduction of the cv.jit.label which I have studied abit (not getting any wiser of the help file tho)

Hope someone can help me. Just need to sort out this filter, to move on.

Thanks.

Regards AnneKristine

as for filtering things out, many of the jit.cv objects include methods for creating a binary image (useful for filtering out unwanted parts). the jitter tutorial 25 has colour tracking elements in it too. jit.cv.track can also track an arbitrarily large number of points.
