I made a patch for school last year that involved motion detection through a webcam. My problem is that I seem to have deleted it inadvertently and though I can remember how I did it, I can't remember the details.

Specifically there was one stage where identical frames would be subtracted from the output so that whenever no one was moving it wouldn't send any information.

I can't for the life of me remember how I did this. Does anyone have any ideas?

The cv.jit library is very nice too.

[jit.qt.movie] into [t l l] then both outputs swapped into their opposite inputs on a [jit.op @op absdiff] and then possibly into something like [jit.glop @gain 0.9] to blur or smooth the motion differencing

Thank you all so much. I'm going try this out on my lunch break!

jit.change seems to be just what I needed. I'll follow up when I get everything working. Thanks everyone!
