1、(论文) 摘要 I 摘 要 人脸识别因为在驾驶员疲劳驾驶、 视频会议、 医学、 档案管理、 系统公安 (罪 犯识别等) 等方面的巨大应用前景越来越成为模式识别和人工智能领域的一个研 究热点,其中,由于眼睛与人脸部的其他部位相比,其灰度变化特征十分明显, 因此,人眼定位研究算法对于人脸识别系统有着非常重要的意义和影响。 在常规的光线下,人眼区域在人脸区域中有两个显著地特征,一个是较周围 的区域暗,另一个是灰度差值较大,因此,本文使用了一种通过灰度积分和微分 投影的眼睛定位方法,其前提是在人脸区域中进行人眼定位,可用于疲劳驾驶检 测中的人眼快速定位。在从人脸区域中去除容易被分隔出的,又影响人眼定位
2、的 干扰信息的基础上, 利用水平和垂直灰度微积分投影的方法并结合人脸的结构特 征得到眼睛的位置坐标。 该算法利用 Visual C+编写程序,运算时间较短,结合简单有效的灰度投影 分析,大大提高了定位的速度,并且定位较准确。 关键词:水平和垂直灰度微积分投影;灰度投影; 人眼定位 (论文) Abstract II Abstract Face recognition for the pilot fatigue driving,video conference, medicine, human-computer interaction, file management, public securi

4、ion algorithm research for face recognition system has a very important significance and influence. In conventional light, the human eye area in the face region are two significantly feature, a is the area surrounding the dark, the other is a gray level difference is bigger, therefore, this paper uses a through the gray integral and differential projection eyes positioning method, the premise is the face region in the eye location, can be used
