A Note on Visualization of Video Retrieval Based on Perceptual Grouping
Details
This paper proposes a visualization method of video retrieval based on perceptual grouping. The perceptual grouping is a perceptual phenomenon which a human perceives figures as unities in eyeshot. We have previously proposed a video retrieval system for providing the videos desired by the users if users do not have specific queries. However, in traditional method, the interface is not considered a past search history. Thus, users cannot distinguish precisely between a similar video and a video provided newly from past search results. And, it becomes difficult to confirm the change of the video search results in a series of flows along the search history. Therefore, the proposed method arranges the videos in the three-dimensional space. Furthermore, we visualize the video retrieval results based on the perceptual grouping. Consequently, the effective visualization of the video retrieval results is discussed.
