基于Qt／Embedded的虹膜定位算法

虹膜识别被认为是目前最准确可靠的生物特征识别方法，而快速、准确地定位虹膜是虹膜识别系统的关键。在研究了基于Snake模型的虹膜定位算法的基础上，对Snake算法进行了改进，提出了一种采用多次定位的Snake算法对虹膜进行内定位，而对外定位则采用一种简化的Daugman圆形边缘检测算子的方法；并在Linux系统下采用QT编程实现了虹膜图像定位的整个过程。实验结果表明，该算法定位准确，较大地改善了其实时性，并能较好地支持嵌入式系统。

Iris location algorithm based on Qt/Embedded

Iris recognition is regarded as the most reliable and accurate biometric identification method available.The key of iris recognition is locating iris quickly and accurately.Based on the research on an iris localization algorithm of Snake model,an iterative Snake algorithm was proposed to locate the inner boundary of iris through improving the Snake algorithm.A simplified Daugman circle detection operator was used to locate the outer boundary of iris.The iris localization algorithm was realized with QT in Li...
