Real-time eye detection using face-circle fitting and dark-pixel filtering

Real-time eye tracking is a challenging problem. A face-circle fitting (FCF) method is proposed to confirm the extracted face region. Once the face is detected, a dark-pixel filter (DPF) is used to perform eye detection and tracking. Furthermore, The proposed system has been implemented on a personal computer with a PC-camera and can perform eye detection and tracking in real-time. The correct eye identification rate is as high as 92% during the actual operation.
