Because of its uniqueness , reliability , and against artifice merits , iris recognition technology has been making fast development . furthermore , it will be proved to widely apply 由于虹膜具有唯一性、稳定性、非侵犯性等优点,近年来,虹膜识别技术研究和应用方面都得到了长足的发展,并表现出广阔的应用前景和较大的市场需求。
The algorithm has made certain improvement and innovation in each stage of the iris recognition . the identification experiments are done in the casia iris database ( version 1 . 0 ) , and good recognition results are achieved 该算法在前人研究的基础上,对虹膜识别的三个阶段(虹膜图像预处理、虹膜特征提取、匹配识别)都做了一定的改进和创新。
Different weighting coefficients are used to multiply the matching result of each part . good recognition results are achieved after 40000 recognition experiments have been done in the casia iris database ( version 1 . 0 ) 论文的最后对本文的虹膜识别算法在casia虹膜数据库( version1 . 0 )中进行了40000次的虹膜识别实验,并得出了较好的识别效果。
For this reason , iris - identification is regard as a kind of noninvasive human identification technique . this paper elucidates the principles and the typical structure of iris - identification system and study svm theory to classify 本论文包括两大部分，第一部分对整个虹膜识别系统进行了研究，第二部分对以统计学习理论为基础的支持向量机分类算法进行了研究。
For example , the characteristics of one ’ s iris are steady all one ’ s life , the capturing of iris image is non - invasive , and issues of iris possess the characters of living issues on account of the zooming process of pupils , which prevents counterfeiting 虹膜识别技术具有以下特点:虹膜图像的采集具有无侵犯性;瞳孔的缩放使虹膜组织具有活体组织的显著特征,可以有效的防止人工伪造等等。
During various external features of human body , iris has very special structure which provides the iris identification with excelsior accuracy . iris identification technology is regarded as one of the most promising biometric recognition technology 在人体的各种外部特征中,由于虹膜结构的特殊性,利用虹膜进行身份鉴别具有更高的准确率,目前虹膜识别技术被广泛认为是最有前途的生物识别技术之一。
