Hi there, I too am interested in your results. I am writing an app to determine when the person Blinks, and then do something while they are blinking, I am using open CV in processing and it sort of works , but slow. I think if I can apply, Hough Circle Transform, I would be able to focus on the pupil, and everything will run much faster. How were you able to use this inside the processing IDE? Did you find out the line that you need to put on the top to import it from Java? the OpenCV library for processing does not include this… at least I have not been able to find it…
Many thanks
