Content-based retrieval of video sequences under partial occlusion

In this paper, we present a spatio-temporal segmentation method for content-based video retrieval. Our method is effective in the presence of partial occlusion or when new areas become exposed. In addition, periodic spatial segmentation is not performed. Rather, it is invoked as needed depending on whether or not new regions have been detected. A discussion of how this method can be used for content-based retrieval is also provided. Finally, experimental results that demonstrate the performance of the proposed spatio-temporal segmentation method are presented.
