Abstract

This paper develops a novel technique of face detection using brightness distribution in the surrounding area of eye. The proposed face detection consists of facial component candidate extraction, facial component candidate filtering through eye-lip combination, left/right eye classification using brightness distribution, face verification confirming edges in nose region. Because the proposed technique don't use any skin color, it can detect multiple faces in color images with complicated backgrounds and different illumination levels. The experimental results reveal that the proposed technique is better than the traditional techniques in terms of detection ratio.

본 논문에서는 눈 주변의 명암분포를 사용하여 영상에 존재하는 얼굴을 탐지하는 새로운 기술을 개발한다. 제안하는 얼굴탐지의 기본적인 절차는 얼굴구성요소 후보 추출, 눈과 입의 형태정보를 이용한 얼굴구성요소 후보 필터링, 눈 후보 주변영역의 에지와 명암분포를 인공신경망 에 적용하여 좌/우안 분류, 눈-입 조합을 통한 얼굴후보 추출, 코 영역 에지의 존재 유무를 이용한 얼굴 검증 순이다. 본 논문에서 제안하는 방식은 눈의 주변영역 정보를 인공신경망에 적용하여 좌/우안 정보를 산출하여 얼굴을 탐지하는 것에 중점을 두고 있다. 이 방법은 피부색상을 이용하지 않으므로 다양한 조명환경과 복잡한 배경을 가지는 영상들에 존재하는 얼굴을 탐지할 수 있다. 탐지율 관점에서 기존의 주요 방법들 보다 우수함을 실험을 통하여 보인다.
