摘要: 描述了基于虹膜识别的身份鉴别系统.该系统包括虹膜图像摄取、图像预处理、特征提 取和匹配四个部分.虹膜图像摄取采用了自主开发研制的装置,特征提取采用Gabor滤波和 Daubechies-4小波变换等纹理分析方法,匹配采用方差倒数加权欧氏距离方法.与现有的其它 方法相比,该方法利用了二维虹膜图像丰富的纹理信息并具有旋转、平移和尺度不变性.Abstract: A personal identification system based on iris patterns is presented in this paper. It is composed of iris image acquisition, image preprocessing, feature extraction and matching. Iris feature extraction is based on texture analysis using multichannel Gabor filtering and Daubechies-4 wavelet transform. Compared with existing methods, our method emplores the rich 2-D information of the iris and is translation, rotation, and scale invariant.
