I am wandering if I could use vvvv to track pupil on a video (eye closeup). Is there a way to do a circle fitting (something like fitEllipse from OpenCV) to get subpixel precision of the pupil center. My output would be really just x/y array I would analyze afterwards.
hello,
you might get lucky with some image processing, but you could also wait for this 99$ device which should ship soon and thanks to a kind user @synth we will get one and will implement the SDK to use it with vvvv.
