Re: [Motion-user] External commands?

[Steve G. <sg...@gm...>]

Hey Jeff, you are probably better off with OpenCV since you have a lot of
control over not just simple motion detection, but picking contours out of
images, tracking and recognition. I'd go with the Python bindings unless
you are a C/C++ guy for ease of use. Just Google OpenCV...
