一个基于多层结构的快速眼睛定位算法
摘 要
眼睛的位置是人脸识别过程中一个很重要的信息。针对灰度人脸图像上的眼睛定位问题,提出了一个基于多层结构的快速眼睛定位算法。该算法首先利用极小值区域(MER)进行眼睛粗定位;然后使用三层筛选算法逐步去除错误的候选保留唯一的正确候选;最后使用眼睛精确定位算法来校正眼睛的位置。该算法在CAS PEAL人脸数据库、JAFFE数据库和自建数据集上均有良好表现,是一个行之有效的方法。

A Fast Hierarchical based Algorithm of Eye Locating
() Abstract
The eye positions are very important landmarks in face recognitionIn this paper a fast hierarchical based algorithm is proposed to locate eyes from face imagesThis new algorithm involves three main stepsFirst,MER(minimum extremal region)is introduced here to locate eye roughlyThen,a three layer filter is applied to rule out false detections step by stepFinally,an accurate eye locating method is used to adjust the eye locations preciselyThis algorithm has good results in CAS PEAL,JAFFE and our own face databaseTherefore,it is considered to be an effective method
