一种改进的模板匹配眼睛定位方法

An Improved Template Matching Eye Location Method

针对眼睛定位问题,文章提出了一种改进的模板匹配方法。在使用一种合成的眼睛模板对图像进行匹配得到多个相似眼睛点的基础上,利用人脸库部分图像中两眼相对位置关系的统计值来构造一个分段距离函数,并计算相似眼睛点的两两距离,根据此距离信息来同时定位双眼。实验结果表明,与传统模板匹配方法相比,该文方法能够同时定位双眼,并显著提高了定位准确率和定位速度。

In this paper,an improved template matching method is proposed for the eye location problem.First,several similar eye points are obtained using a synthetic eye template to match the face-image.Then it constructs some distance function according to the two eyes' symmetrical relationship.Finally,the two eyes are located by calculating the distance among the similar eye points.The experimental results show that the new method can locate two eyes simultaneously,get higher precision and faster speed comparing with the traditional template matching algorithm.
