grid tracking

Jul 31 2008 | 8:58 pm

Hi, all!

I’m working on a project that involves both detecting motion and placing that motion on a grid in order to extract x,y coordinates, which will control effects parameters.

While I’m able to use jit.change to detect/track the amount of motion in a video feed, I am having trouble mapping or placing the matrix on a grid. Is there any object, or combination of objects, that would accommodate this process? I simply need to be able to pull the x,y coordinates of what is currently moving in relation to a 0,0 (center) point.

Thanks to everyone for any help and/or advise.

Hi Anna,

In case you haven’t already used them, the cv.jit library of externals would be a great resource for you. Play around with them a bit, then let us know if you need more guidance.

You can get the objects here:

Thank you so much, I can tell I’ll learn a lot from this!
I really appreciate it.
