摘要:

虹膜识别系统是基于眼睛的生物识别设备,主要用于安全原因。虹膜的复杂性和随机性,以及其他各种因素,确保了这种生物识别系统无疑是一种准确可靠的识别方法。该算法是负责自动定位和分割的边界,使用圆形霍夫变换,降噪,图像增强和特征提取在数据库中存在的许多不同的图像。本文深入研究了各种所需的技术,以近似瞳孔和边缘的注册虹膜图像的边界,捕获使用合适的图像采集设备和执行特征提取的归一化虹膜图像的帮助下,哈尔小波编码的输入数据成二进制字符串格式。这些技术使用CASIA数据库中的图像进行了验证,还尝试和测试了各种其他程序。

英文摘要:

Iris Recognition Systems are ocular- based biometric devices used primarily for security reasons. The complexity and the randomness of the Iris, amongst various other factors, ensure that this biometric system is inarguably an exact and reliable method of identification. The algorithm is responsible for automatic localization and segmentation of boundaries using circular Hough Transform, noise reductions, image enhancement and feature extraction across numerous distinct images present in the database. This paper delves into the various kinds of techniques required to approximate the pupillary and limbic boundaries of the enrolled iris image, captured using a suitable image acquisition device and perform feature extraction on the normalized iris image with the help of Haar Wavelets to encode the input data into a binary string format. These techniques were validated using images from the CASIA database, and various other procedures were also tried and tested.
