Notice of RetractionInside canthus location algorithm design based on susan operator

The research is unfolded on eye location, tracking and study the state of the eye in the eye recognition system. By means of improving traditional Susan operator, we design the corner extraction operator of precise positioning of the eye. According to the characteristics of external environment being no interference to the inner corner of the eye, the research extracted a small corner of the template for the eye tracking. The design operator can adapt to variation in complex background and have higher computational efficiency. According to VC + + platform experiment, the results show that detection accuracy rate of standard frontal face comes to 95%, and of monitoring image detection “eyes - face” window position comes to 90%.
