Abstract

Palmprint-based personal identification system, as a new member in the biometrics system family, has become an active research topic in recent years. Although lots of methods have been made, how to represent palmprint for effective classification is still an open problem and conducting researches. In this paper, the palmprint classification and recognition method based on PCA (Principal Components Analysis) using the dimension reduction of singular vector is proposed. And the 135dpi palmprint image which is obtained by the palmprint acquisition device is used for the effectual palmprint recognition system. The proposed system is consists of the palmprint acquisition device, DB generation algorithm and the palmprint recognition algorithm. The palmprint recognition step is limited 2 times. As a results GAR and FAR are 98.5% and 0.036%.

장문기반의 인식시스템은 생체인식 시스템의 새로운 방법으로 대두되어 지고 있으며 현재 많은 연구가 활발히 진행되어지고 있다. 비록 많은 장문 인식 알고리즘이 만들어지고 있지만 장문을 효과적으로 분류하는 방법에 대한 연구는 아직까지 활발히 진행 중이다. 본 논문에서는 특징벡터의 차원축소를 이용한 주성분 분석법(PCA)을 기초로 한 장문 분류 및 인식 방법을 제안하였다. 그리고 효율성 있는 장문인식 시스템을 설계하기 위하여 장문획득 장치를 사용하여 135dpi 장문이미지를 획득하여 사용하였다. 제안된 장문인식 알고리즘은 장문획득 장치, 데이터베이스 생성 그리고 장문인식 알고리즘으로 구성되어 있다. 장문인식 단계는 2회로 제한하였으며, 그 결과 GAR 및 FAR이 각각 98.5%, 0.036%의 성능을 보였다.
