I would like to implement very basic motion tracking with a USB camera. I have already got the usb camera showing in labview (using a modified version of the USB example). What I would like to do is take the current frame in the buffer, subtract it from the previous frame in the buffer, increase contrast, and find all nonzero pixel values. These values would be the locations where change has occured. I've been using labview for only a week, so this may be a simple task, I just can't figure out how to grab the last frame in the buffer. I think I know how to grab the current frame. Anyways, any help would be greatly appreciated.
Thanks in advance,
Jack Minardi
