tracking corners with cv.jit

February 16, 2012 | 4:58 am

I’m working on a kinetic video installation and need to track the corners of a moving rectangle in a depth map from a kinect. (See http://vimeo.com/36880386 for reference.) I want to use the position of the corners of the object to map a mask to the object. (Sorta like http://vimeo.com/11026197 but with the rectangles rotating as in the depth map video referenced above.) Any suggestions on how a cv-challenged individual might accomplish this?

I’d try limiting the tracking matrix to just the rectangle (using depth), then cv.jit.features2track, then only use the track points at the outer corners.

there’s probably a better way, but that’s my idea.
