초록

본 논문에서는 방대한 양의 방송 데이타를 처리하기 위하여 MPEG(Motion Picture Expert Group) 스트림 비디오에서 빠르고 효과적으로 비디오를 분할하는 기법을 제안한다. 이를 위해, MPEG 압축 도메인에서 최소 디코딩을 수행하여 I-프레임의 DC 이미지를 추출함으로써 통해 실행 시간을 단축하고, 밝기 정보와 색상 정보를 함께 고려한 변형된 히스토그램 비교법을 도입하여 장면전환을 빠르고 정확하게 검출하였다. 그리고 추출된 장면전환에 대해 앵커 프레임과 비앵커 프레임을 구별하기 위해 신경망 기법을 도입하였다.

In this paper, an efficient and fast method to segment a video in the MPEG(motion picture expert group) video stream is proposed. For the real time processing of large amount of broadcasting data, we use DC images of I-frames in an MPEG compressed video with minimal decoding. Using the modified histogram comparison which counts on not only luminance but also chrominance information, the scene change detection was performed in the fast and accurate way Also, to discriminate anchorperson frame from non-anchor frame, a neural network method was introduced.
