최근 생체 인식 분야나, HCI 분야 등에서 사람의 눈 영상 정보를 이용하여 홍채 인식을 하거나 시선 위치 정보를 이용하는 연구가 활발히 진행 되고 있다. 특히 사용자의 편의성을 위한 원거리 카메라 기반 시스템이 늘어나면서 눈 영상 촬영에 단순히 동공 중심 영역만 촬영 되는 것이 아니라, 눈썹, 이마, 피부 영역 등 부정확한 검출을 일으킬 수 있는 요소가 포함되어 촬영되고 이러한 불필요한 요소들은 동공 중심 영역의 검출 성능을 저하시킨다. 또한 앞서 얘기한 이용분야들은 실시간 환경에서 실행되는 시스템들로 정확한 검출 성능뿐만 아니라 빠른 실행시간도 요구 한다. 본 논문에서는 정확하고 빠른 눈동자 영역 검출을 위하여 기존에 가장 많이 사용하는 AdaBoost 눈 검출 알고리즘, 적응적 템플릿 정합+AdaBoost 알고리즘, CAMShift+AdBoost 알고리즘, rapid eye 검출 알고리즘에 대하여 분석하고, 조명변화와 콘택트 렌즈 및 안경 착용자와 미 착용자등 다양한 경우에 대해서 앞서 말한 알고리즘들을 적용하여 각 알고리즘 별로 정확도와 실행시간을 비교 분석하도록 한다.
