| 摘 要： | 提出了人脸图像中眼睛定位方法，首先对灰度图像进行灰度形态学操作，所得谷图中像素数总体上随灰度级的增加而显著减少；用位于高端的灰度值作为阈值，逐次对谷图进行二值化，从所得二值图像中获得眼睛的候选位置；用PCA方法进行眼睛位置的最佳选择．该方法解决了二值化阈值步长的自适应选取问题．用AR，Yale和自建人脸数据库进行实验，得到眼睛定位成功率大于93％，平均定位偏差小于眼球半径的1／3． |

| Abstract: | In this paper, a novel method for automatic localization of human eyes from front-view face images is presented. By applying the grayscale morphology operation to a face image, we can obtain a valley map with a good property in which as a whole the number of pixels at a grayscale decreases significantly as the grayscale level increases. The valley map is then binarized with a set of threshold values determined adaptively, and several candidate eye locations are detected from the resultant binary images. The final eye positions are determined using a Principle Component Analysis (PCA) method. Experimental results on the AR, Yale and our own face image databases show that the correct eye location rate is over 93% and the location disparity on average is below 1?3 of the radius of an eye ball. |
