A new fast method of pupils localization based on gray-level projection and Harris corner detection is proposed.First,the left and right boundaries of face is localized with vertical gray-level projection.Secondly,face region's horizontal gray-level projection is used to localize the top of the head and the middle of the nose.Finally,locating the exact positions of pupils rapidly using Harris corner detection,accordingly,the exact positions of the eyes is located.This algorithm is successful Harris corner detection algorithm applied to the pupil position,the experimental results demonstrate that the algorithm without the interference of eyebrow,a smaller computing capacity and higher processing speed and locating accuracy,higher accuracy rate,solve a human eye's rapid positioning in simple background.
