基于匹配分数的多生物特征识别融合综述

摘要

受数据噪音和识别系统本身的限制,基于单一生物特征的身份认证系统所能达到的准确率是有限的.通过多生物特征识别来提高识别的准确率成为当前生物特征识别领域的研究热点之一.首先介绍了多生物特征识别的必要性、多生物特征识别的分类,然后重点介绍了基于匹配分数的多生物特征识别融合的研究现状,最后总结了多生物特征识别研究中的问题和未来的研究方向.%Influenced by data noise and limitation of recognition system itself, the accuracy of identification system based on single biometric trait is proved to be quite limited. Therefore, the research of using multi-biometric recognition for improving recognition accuracy has become one of the hotspots in biometric recognition field. This paper first introduced the importance of multi-biometrics, the classification of multi-biometrics, and then mainly discussed the current study on score-based multi-biometric recognition. At the end, this paper concluded the problems and the future work in multi-biometrics.
