| 摘 要： | 利用灰度投影曲线检测预处理后的人脸图像眉眼区域,并分割左右眼区域;结合梯度投影和方差投影函数构造区域混合投影函数,分别对左右眼区域进行混合投影;分析一系列的投影峰,筛选后得到眼睛中心的准确位置.在ORL和BioID人脸库上的实验表明：在姿态和光照变化较大及佩戴眼镜的情况下,利用混合投影函数峰分析定位眼睛的结果优于单个投影曲线.

| Abstract: | The grey projection curve is used to detect the eye era of a pretreated human face and segment the right and left eye areas;the gradient and variance projection are combined to construct regional hybrid projection function to respectively conduct mixed projection on the right and left eye areas.A series of projection peaks are analyzed and the exact location of the eye center is obtained after screening.Experiments on ORL and BioID face databases show that peak analysis making use of mixed projection function is of better accuracy than the single projection curve when the variation in illumination is great and when the face wears glasses. |
