中文摘要: 提出了一种基于Hough变换的虹膜定位方法.根据虹膜图像特征,按内外边缘定位需要,采用不同尺寸模板的中值滤波器对原始图像进行预处理,再采用圆形Hough变换投票决定其内外边缘精确位置.根据对100多幅虹膜样本的处理结果表明,此算法具有快速、精确、鲁棒等特点.
Abstract:The paper introduces an iris location algorithm based on Hough transform. According to the features of iris image, the image is pretreated with medium filter of different size for needs of locating inner and outer boundaries. And then the circular Hough transform is applied to find the exact location of inner and outer boundaries. Experiments on more than 100 iris samples show that the algorithm is fast, accurate and robust.
