该程序用于实现虹膜图像的定位，用点线检测的方法代替传统的圆检测方法-The program used to implement the positioning of the iris image, with points and lines to replace the traditional method of detecting circle detection method

1.GeometricContext文件是完成图片中几何方向目标分类。 参考文献《Automatic Photo Pop-up》Hoiem 2005 2 GrabCut文件是完成图像中目标交互式分割 参考文献《“GrabCut” — Interactive Foreground Extraction using Iterated Graph Cuts》 C. Rother 2004 3 HOG文件是自己编写的根据HOG特征检测行人的matlab代码 4 虹膜识别程序

first it detects edge by canny edge detection method then it uses hough transformation to find circles in an image. after that it detects the iris
