摘要:

本文提出了一种改进的鼻侧和颞侧眼角检测算法。该算法是Santos和Proenka方法的改进。在第一步中,我们使用基于Haar类特征的分类器来检测面部和眼睛。然后,我们从检测到的眼睛区域分割出巩膜。从分割的巩膜,我们分割出一个近似的眼睑轮廓。使用Harris和Stephens角点检测器获得眼睛角点候选。最后,我们引入了一个后修剪的眼角候选人定位眼角。该算法已经在Yale,JAFFE数据库以及我们创建的数据库上进行了测试。

英文摘要:

In this paper, a modified algorithm for the detection of nasal and temporal eye corners is presented. The algorithm is a modification of the Santos and Proenka Method. In the first step, we detect the face and the eyes using classifiers based on Haar-like features. We then segment out the sclera, from the detected eye region. From the segmented sclera, we segment out an approximate eyelid contour. Eye corner candidates are obtained using Harris and Stephens corner detector. We introduce a post-pruning of the Eye corner candidates to locate the eye corners, finally. The algorithm has been tested on Yale, JAFFE databases as well as our created database.
