摘要
虹膜识别是一种新颖的基于生物特征的身份鉴别方法 ,在信息及安全领域有着重要的应用价值 .在总结前人工作的基础上 ,就虹膜成像、虹膜区域定位、预处理机虹膜纹理编码等关键技术进行了讨论 ,给出了一些相关的改进及创新算法 ,实现了一套基于虹膜识别的身份认证系统 。
Iris recognition is a new method for man identification based on the biological features, which has the significant value in the information and security field. Combined with the previous work of other researchers, a discussion is elaborately made on the key techniques concerning the capture of iris images, location of iris circle and coding of iris texture, and some improved and creative approaches to these problems are put forward. The system of iris recognition is realized which proves efficient.
