摘要:

为解决瞳孔检测中眼镜反光、眼帘遮盖、闭眼等问题,提出了一种基于改进对称变换的
瞳孔定位方法。根据人脸的梯度信息、人眼瞳孔区域与眼镜反光区域梯度方向不同的现象,
改进对称变换算法,以提高定位准确性,采用自评估算法对定位进行评估,并利用自采
集的图像和图库中的图像进行了实验。结果表明,改进的对称变换算法能对瞳孔进行精确定位。

关键词: 对称变换, 瞳孔定位, 自评估

Abstract:

Based on advanced symmetry transform,a pupil localization method was studied.In
order to solve low accuracy problem of localization because of reflection of lig
ht bringing of glasses,overspread of eyes and closed eyes,etc, the symmetry transfor
m method was improved based on different gradient information between area of pu
pil and area of reflecting light of glasses.In order to improve accuracy of loca
lization,a self evaluation method was applied.Experiment results o
f collected pictures and pictures in library showed that the method can localize the situation of pupil precisely

Key words: pupil localization, symmetry transform, selfevaluation
