In this paper, we describe two visualization approaches for multi-video summaries. Visualization of video summary is important for discovering the relations among the frames of different videos. And it is useful in evaluating the video summary and comparing the summaries from different algorithms. In one of our approaches, we exploit a circle space to visualize the relations between multi-video frames. While in the second approach, we illustrate a summarization method based on hierarchical clustering and present its corresponding visualization. Both presentations are used in actual experiments for producing summaries from a set of videos.
