Location algorithm for eye pupil based onskin color features and genetic algorithm
基于肤色特征和遗传算法的人眼瞳孔定位算法

This paper presented a location method for the human eye pupil with single camera, which was divided into three stages, face region detection, eye region detection and pupil center location. In the face region detection stage, combining the method of regional growth, it separated the face region by the space character of face's skin color and lip color under different chromaticity. In the eye region detection stage, using the face region positioned, according to prior knowledge, it narrowed the search area, and then searched the eye area with the genetic algorithm. Finally, it positioned pupil center by the geometrical properties of round. Simulation results indicate this algorithm is effective in complex background and circumstances of head deflection.
