摘要:
 虹膜阳光放射沟是人体器官发生病变表现在虹膜上的其中一种形式。它表现为放射状的线条且在整个虹膜范围内都可能会出现。文中针对虹膜中阳光放射沟特征的检测进行了研究，分析了阳光放射沟的灰度特征，提出了基于窗口提取的方法来对阳光放射沟进行检测。首先，对人眼虹膜进行预处理。其次，针对阳光放射沟的特点设计出窗口。然后，通过窗口提取出阳光放射沟的候选像素并进行筛选。最后，利用阳光放射沟的长度及位置特征进行检测。在实验室采集的虹膜图库中，检测正确率达到91.3%。实验结果表明，该算法在复杂性程度和阈值选择上有很大优势。
Abstract:
 Iris radii solaris is one of the forms of the human’ s organ’ s pathological changes. It is shown as radial lines and it occurs in the whole iris. The detection has been studied for the characteristics of the radii solaris in the iris,analyzing the gray features of radii solaris, putting forward the method of window extraction to detect the radii solaris. First of all,preprocess the iris image. Secondly,according to the characteristics of the radii solaris,design the window. Then,through the window extract the candidate pixel of radii solaris and select. Finally,detect radii solaris by the length and position characteristics of the radii solaris. To the laboratory iris database,the location accura-cy of this algorithm can reach 91. 3%. Experimental results show that this algorithm has many advantages in the complicated degree and the thresholds selection.
