读入人脸图像，根据图像的水平，垂直灰度积分情况，将人眼范围取出，背景可以较复杂。

定位人眼，对二值化图像进行积分投影便可准确定位人眼。分别对人脸图像进行水平/垂直积分投影，并对投影曲线归一化，便可得到眼睛中心水平坐标。-The positioning of the human eye , the integral projection of the binary image can be accurately positioning the human eye . Horizontal/vertical integral projection of the face imag

对人脸候选区域中眼睛特征部位采用水平垂直积分筛选出眼睛部位，并将其标注在图像中。(The eye location is selected by horizontal vertical integral in the eye area of the face candidate area, and it is labeled in the image.)
