摘要
采用经典Canny算子进行虹膜边缘检测,利用一种改进的hough变换算法定位出虹膜的内外边缘,实现对虹膜图像的预处理,从而为虹膜特征提取和图像识别提供可靠的依据。
Though using Canny arithmetic operators for iris margin detecting and improved hough translation for the orientation of iris's inside and outside margins, we realize the image Preprocessing. It provides a reliable foundation for iris feature extraction and orientation.
