Abstract An eye localization method based on projection peak is presented. Firstly, according to the proportional relationships of face features, the eye region from an face image is segmented by setting appropriate candidate window. Then, by means of histogram analysis of the eye region image, a threshold is obtained and binary transform is performed to segment the eyes out of the eye region. Next, a series of projection peak is derived from vertical and horizontal gray projection curves of the binary image. Through comparison and analysis, the exact coordinates of the eyes is finally confirmed. The presented method has no need of any previous knowledge and training process. Experimental results on three face databases show that the proposed method is effective, accurate and rapid in eye localization and it meets the requirement of real-time face recognition system entirely.
