Eye localization based on hue image processing

Abstract

A new eye localization method based on hue image processing is proposed in this paper. First, face extraction method based on skin-color information is improved by forehead skin localization and lip detection. Second, vertical projection in hue image is used instead of horizontal projection in intensity or edge images in other works. At last, the eye center is located by a peak value extraction algorithm. This method is time efficient as no gradient or other time consuming computations are used. The experiment result shows that a 320times240 color image needs 8 ms to locate the centers of both eyes on a PC with an AMD Sempron TM 2500+ at 2.25 GHz CPU. The average detection rate is about 95.25%.
