Description: 包括整个虹膜识别的预处理部分，分为多个函数部分，即简单图像增强，Canny算子提取边缘，Hough变换定位内外圆形边界进行风格，以及最后的归一化 -- 将圆环展为矩形。附带几张图像及自制的界面程序，并不是很完善，但整体的预处理任务已经较好的完成，如果进一步提高性能，可以先把Hough变换改为最小二乘拟和算法。-Cover the whole iris recognition pre-processing part is divided into multiple function part, that is, a simple image enhancement, Canny operator edge extraction, Hough transform internal and external circular positioning border style, and finally normalized Circle exhibition will be rectangular. Fringe images and made a few interface procedures, is not very perfect, but the overall pre-processing tasks have been better to complete, if further improve performance, first Hough transform can be replaced by least squares fitting algorithm.
