I’m no tracking wiz, but jit.cv.blobs.centroids (or whatever it’s
called) outputs x/y coordinates for the blobs, right? I would send
these through a [cartopol] and then sample the theta output. There’s a
bit of trickery involved while crossing from 360 to 1 degree as far as I
remember, but that can be solved with some logic.
