added cropping
made shitloads of comments changes
hallelujah it can detect the pupil and plot it in realtime
removed the greyscale subplot, it's mucho faster now and possibly realtime
reduced the sensitivity, now its able to detect only the pupil, awesome
comment
now plotting greyscale image only
optimized size of window for cropping
added a 1k resistor instead of a 2.2k and ysed a fresh battery - now the pupil's being detected real well
just some comments, stable version
