摘要
提出一种基于投影峰的眼睛快速定位算法.该算法首先根据人脸的几何分布特征设置眼睛候选窗口.再通过直方图阈值分割出眼睛.然后经过灰度积分投影得到一系列投影峰,经过比较筛选得到眼睛的精确位置.算法简单高效,不需要训练和学习过程.实验结果表明,该算法能够快速准确地定位眼睛位置,满足实时自动人脸识别的需要.
An eye localization method based on projection peak is presented. Firstly, according to the proportional relationships of face features, the eye region from an face image is segmented by setting appropriate candidate window. Then, by means of histogram analysis of the eye region image, a threshold is obtained and binary transform is performed to segment the eyes out of the eye region. Next, a series of projection peak is derived from vertical and horizontal gray projection curves of the binary image. Through comparison and analysis, the exact coordinates of the eyes is finally confirmed. The presented method has no need of any previous knowledge and training process. Experimental results on three face databases show that the proposed method is effective, accurate and rapid in eye localization and it meets the requirement of real-time face recognition system entirely.
