A Reflection and Occlusion Robust Eye Center Searching Algorithm

Eye center detection is an essential module in iris segmentation and gaze tracking. It is more challengeable to achieve this goal using a usual web camera under natural illumination. The image resolution and the eye region scale are main problems. Focusing on solving these problems, this paper proposes a robust eye center searching algorithm which can locate the iris including the center and the radius in Id searching time consuming. Experiment shows an excited result. Compared with the well known Hough and Integral Differential, this method also is robust to the reflection and occlusion.
