摘　　要：眼睛的精确定位是人脸识别预处理的关键步骤,是人脸旋转角度和尺度归一化的前提。文章介绍了一种精确定位眼睛的方法,该算法将眼区灰度总体分布特点与眼部灰度变化特点相结合;将传统的积分投影方法与本文提出的微分投影相结合;实验结果表明,该算法对光照变化不敏感,定位准确率高。As the premise of face rotation and normalizing, locating eyes accurately is a pivotal step in the pretreatment of face recognition. A method of locating eyes accurately is described in this paper, which combines the overall distribution characteristics and the change of luminance. The presented algorithm combines the traditional integral projection method and the differential projection method which is proposed in the paper. Experimental results show that the given algorithm is not sensitive to the illumination and eyes can be located quite accurately.
