Gradual shot change detection is one of the most important research issues in the field of video indexing/retrieval. Among the numerous types of gradual transitions, dissolve is considered the most common one, but also the most difficult to be detected one. It's well known that an efficient dissolve detection algorithm which can be executed on a real video is still deficient. In this paper, we present a novel dissolve detection algorithm that can efficiently detect dissolves with different durations. In addition, global motions caused by camera movement and local motions caused by object movement can be discriminated from a real dissolve by our algorithm. The experimental results show that the new method is indeed powerful.
