摘 要: 介绍一种精确定位眼睛的方法.眼睛定位是很多人脸检测算法的关键步骤.在获得眼睛窗口之后,可以利用投影方法来定位眼睛.提出一种混合投影函数,该函数结合了积分投影函数和方差投影函数,能够反映出图像在某个方向上灰度均值和方差的综合变化情况.实验结果表明,利用混合投影函数可以相当精确地确定眼睛 中心的位置.-Abstract: A method for precise positioning of the eyes. Eyes positioning is a lot of face det

首先对图像进行非线性灰度变换滤除噪声，然后利用最大类间方差阈值技术对处理后的图像进行二值化处理，最后利用积分投影定位人眼-First to utilize non-linear gray-scale transformation to filter out noises, then adopts the between-cluster variance threshold segmentation method for image binarization processing, finally

用adaboost对人脸检测，利用haar特征对积分图像进行训练，得到强弱分类器(Face detection is done by AdaBoost, and integral image is trained by Haar feature, and the strong and weak classifier is obtained.)
