> 中文摘要: 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 is described to locate eyes accurately in this paper. Eye location is the key step of many face detection methods. After obtaining an eye window, the eye can be located by using projection functions. A novel projection function, i.e. hybrid projection function (HPF), is proposed in this paper. HPF combines integral projection function and variance projection function so that it can reflect the mean and the variance of the pixels in a particular direction of the image. Experimental results show that eyes can be located quite accurately by using hybrid projection function.
