@antoinelame THX for your awesome job first. But when I try example.py the log gives me the error:

Traceback (most recent call last): File "example.py", line 18, in <module> gaze.refresh(frame) File "C:\Users\Red\.spyder\dolist\pyimage\GazeTracking\gaze_tracking\gaze_tracking.py", line 64, in refresh self._analyze() File "C:\Users\Red\.spyder\dolist\pyimage\GazeTracking\gaze_tracking\gaze_tracking.py", line 51, in _analyze self.eye_right = Eye(frame, landmarks, 1, self.calibration) File "C:\Users\Red\.spyder\dolist\pyimage\GazeTracking\gaze_tracking\eye.py", line 22, in __init__ self._analyze(original_frame, landmarks, side, calibration) File "C:\Users\Red\.spyder\dolist\pyimage\GazeTracking\gaze_tracking\eye.py", line 112, in _analyze self.pupil = Pupil(self.frame, threshold) File "C:\Users\Red\.spyder\dolist\pyimage\GazeTracking\gaze_tracking\pupil.py", line 17, in __init__ self.detect_iris(eye_frame) File "C:\Users\Red\.spyder\dolist\pyimage\GazeTracking\gaze_tracking\pupil.py", line 51, in detect_iris self.x = int(moments['m10'] / moments['m00']) ZeroDivisionError: float division by zero

OpenCV 3.1.0. BTW in eye.py line 86 may have the same issue, but I can't repeat it again and so the log lost.
