Accurate detection of eyes plays an important role in human-machine interfaces. In this paper, according to some physical characteristics, a new designed device for the new real-time and effective eye detection method is proposed. In this device, two physical characteristics are applied, they are the Red-eye effect and the 850-property observed in the experiments. The detecting approach includes four steps, pretreating, matching by SURF (Speeded Up Robust Features), finding the difference and getting the points of the eyes. After these four steps, the positions of the eyes are obtained, and whether eye exists in the picture or not could also be judged. To speed up the detection, the matching parameters are recorded and adjusted periodically. Keywords-eye detection; SURF; red-eye effect;850-property |
