Detecting Gradual Transitions in Video Sequences

비디오 영상에서 점진적 장면전환 검출

Automated video segmentation is important as the first step of video indexing, video retrieval and other uses. Unlike abrupt changes that are relatively easy to detect, gradual transitions like dissolve, fade-in and fade-out are rather difficult to detect. In this paper, we propose a method for detecting gradual transitions based on local statistics and less dependent to a given threshold level. Experimental results show that the proposed method detected about 85% of gradual transitions.
