안개는 실외에서 사용되는 여러 컴퓨터비전 분야 알고리즘들의 성능에 안 좋은 영향을 끼친다. 영상 처리를 통한 안개제거는 컴퓨터비전 분야의 중요한 문제 중 하나이다. 기존의 단일 카메라의 영상만을 이용한 안개제거 방법으로는 카메라의 통계적 속성을 응용한 dark channel prior가 가장 유명한데, 기존의 방법들은 이 dark channel prior를 사용하여 전달량(transmission map)을 구하는 과정에서 정방형 필터를 주로 이용하였다. 정방형 필터(fixed size filter)를 사용하면 필터의 크기가 커질수록 안개제거의 효과가 작아지고, 필터의 크기가 일정 크기보다 작아질 경우 과포화(over saturation)가 발생하여 원래의 영상의 색 정보가 손실되게 된다. 이러한 영향 때문에 필터의 크기를 어떤 값으로 사용하는지가 결과값에 영향을 주게 되어 일반적으로는 비교적 큰 값을 적용시키거나 영상에 따라 과포화가 일어나지 않는 범위에서 작은 값을 사용한다. 본 논문에서는 컬러영상분할을 이용한 향상된 안개제거 방법을 제안한다. 컬러영상분할의 파라미터를 영상 속의 구조의 복잡도 정보에 따라 자동으로 설정하고, 이를 바탕으로 전달량을 추정함으로써 과포화 현상은 일어나지 않고 안개 제거의 효과가 뛰어난 결과를 얻었다.
