I need C++ code that will use the computer's default webcam to identify when the user closes or opens their eyes. You don't need to do any facial recognition per se, you can just assume that in the short time the eyes are opening or closing the user's head is virtually stationary, therefore you can simply look for situations where the overall picture hasn't changed much except for two "blobs" of rapidly changing pixels. You don't need to worry about situations where the user is rapidly turning their head. Requirements: – It has to be precise, with no false positives (such as when the user moves their eyes around without closing them) – it has to work in real-time and store in an array or similar data structure the precise times of all the opening and closing events. – It has to identify blinks, i.e. distinguish them from regular opening and closing events. – It has to work regardless of the orientation of the head, which can be vertical or horizontal (you may assume, however, that the user always more or less faces the camera, such that both of their eyes are clearly visible)

I think this can be done - I say think because we've not done this 'eye close' task before although I have done many opencv face/upper body/people/etc. detection tasks in C++. I'd use opencv2. re: "It has to be precise, with no false positives (such ..." How fast a blink would we need to detect? Some simple calculations involving how fast you can process frames (or even capture them) will tell us how fast a blink we can possibly detect. re: "it has to work in real-time and store in an array ..." Using opencv/c++ "store in an array" is completely doable, but again, how many frames per unit time (fps etc) will determine how fast a blink that may be detected. and the "real-time" latencies involved. Hopefully we can trade off resolution (fps, cpu processing time) to arrive at an acceptable result for you. re: "It has to identify blinks, i.e. distinguish them from.." And see above for caveats. Hardware frame capture rate is one limitation, opencv cpu processing time another. For example, if you can get 10 fps (into memory tops, then you won't be able to reliably detect eye close/open events of under 200 ms. (Nyquist sampling theorem). re: "It has to work regardless of the orientation of the head..." Should be doable, but if you don't know orientation 'ahead' of time then, will take a bit longer (~2-3 times longer for face detection phase internally FWIW).
