Abstract
Color- is used as a method for scene change detection. It extracts a violent scene in an elevator and then could be used for real-time surveillance of criminal acts. The scene could be also used to secure after-discovered evidences and to prove analysis processes. Video Forensic is defined as a research on various methods to efficiently analyze evidences upon crime-related visual images in the field of digital forensic. The method to use differences of color-histogram detects the difference values of histogram for RGB color from two frames respectively. Our paper uses Color- histogram that is composed of merits of color histogram and ones of histogram, in order to efficiently extract violent scenes in elevator. Also, we use a threshold so as to find out key frame, by use of existing Color- histogram. To increase the probability that discerns whether a real violent scene or not, we take advantage of statistical judgments with 20 sample visual images. 키워드 : 장면전환검출, 영상포렌식, 컬러- 히스토그램, 증거, 폭행 Key word : Scene change detection, Video forensic, Color- histogram, Evidence, Violence Journal of the Korea Institute of Information and Communication Engineering 한국정보통신학회논문지(J.
