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 image , and the projection curve normalized , you can get the coordinates of the center of the eye level
