휴대 단말 기기에 대한 관심 증가와 함께 사용자의 얼굴을 검출하는 응용 방법에 대한 연구가 활발히 진행되고 있다. 하지만 주변 조명 등의 영향으로 얼굴 검출이 어려운 문제점이 있다. 이를 해결하기 위하여 다양한 접근방법이 제안되어 왔지만, 제한된 하드웨어에 적용하기에는 높은 복잡도를 가지는 문제점이 있다. 본 논문에서는 이러한 문제점을 해결하고 효율적으로 얼굴 검출 정확도를 향상 시킬 수 있는 조명 대비를 개선 알고리즘을 제안하였다. 이를 위하여 입력된 영상에서 가우시안 분포를 분석하고, 분석된 분포를 기반으로 각기 다른 조명 대비 개선 알고리즘을 적용하였다. 실험 결과 제안하는 방법이 다양한 조명 환경에서 얼굴 검출 정확도를 향상 시키는 것을 확인하였다.
