본 논문에서는 CCTV에서 촬영된 동영상으로부터 차량의 색상 인식을 위한 대표 색상 영역 추출 방법을 제안한다. 차량이 포함된 CCTV영상에서 번호판 영역을 검출한 후 검출된 번호판 영역 정보를 이용하여 배경이 포함되지 않은 차량 전면 영상을 획득한다. 획득된 차량 전면 영상에서 해리스 코너 포인트를 검출하여 대표색상 영역의 위치 확률맵을 생성한 후, 최종적으로 대표색상 정보를 나타내는 관심 영역 정보를 추출하도록 한다. 본 논문에서 제안한 방법의 성능평가를 위해 실제 고속도로 CCTV영상에서 차량이 포함된 영상 총 5,941장을 획득하였으며, 이를 이용하여 대표 색상 영역 검출 성능을 실험하였다. 그 결과 약 94.3%의 검출 성공률을 확인하였다.
