Android/iOS OpenCV Eye Dilation Detection

Looking for opinions on if OpenCV could be or has been used to detect eye dilation on Android or iOS. I haven't found much other than eye tracking开发者_JS百科 and blink detection with the app EyePhone that uses OpenCV. Under perfect conditions, I'm sure it's possible, I'm more curious of seeing a proof of concept, that it can and has been done.

Thank you for your opinion.

try template matching, it gives me best results for now. You can see my sample app: Example app or use haar detector as its at the start of video, but haar detector is slowly and drop fps.
