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.

Description: canny算法源码。Canny 的目标是找到一个最优的边缘检测算法。Canny 算法适用于不同的场合。它的参数允许根据不同实现的特定要求进行调整以识别不同的边缘特性。对于PC上的实时图像处理来说可能慢得无法使用，尤其是在使用大的高斯滤波器的情况下。但也要考虑到处理器速度的不断提升。 -canny algorithm source code. Canny' s goal is to find an optimal edge detection algorithm. Canny algorithm is applied to different occasions. It allows the parameters to achieve specific requirements according to different adjustments in order to identify characteristics of different edge. For real-time image processing on a PC is probably too slow can not be used, especially in the use of a large Gaussian filter circumstances. But we should also take into account the processor speed has been increasing. Platform: |
