초록
생체(biometric) 정보를 이용한 사용자 인증 기술에 대한 관심이 고조되고 있으며, 이 중에서 얼굴인식은 비접촉이라는 장점 때문에 최근 생체인식 분야에서 연구가 활발한 분야 중에 하나이다. 본 논문에서는 얼굴인식의 선행작업인 얼굴검출단계에서 효과적으로 눈위치를 추출하는 방법을 제안한다. 눈 위치 추출을 위하여 영상에 대한 이진화를 반복적 임계치 설정 방법을 통하여 수행하며, 눈의 특성 강화를 위한 가우시안 필터를 사용하여 눈의 위치를 추출하고, 상관관계를 이용하여 추출된 눈의 위치에 대한 검증 단계를 거친다. 논문에서 제안한 눈 위치 추출은 정확도뿐만 아니라, 온라인 시스템에 적용 가능하도록 고려하였고, 온라인 시스템에 적용한 결과 만족할 만한 성능을 보였다.
Abstract
Many researchers have been interested in user authentication using biometric information, and face recognition is a lively field of study of ones in the latest biometric recognition field because of advantage that it can recognize who he/she is without touching machinery. This paper proposes method to extract eye location effectively at face detection step that is precedence work of face recognition. The iterative threshold selection was adopted to get a proper binary image and also the Gaussian filter was used to intensify the properties of eyes to extract an eye location. The correlation was adopted to verify if the eye location is correct or not. Extraction of an eye location that propose in paper as well as accuracy, considered so that may can apply to online system, and showed satisfactory performance as result that apply to on line system.
