Improving Interactive Known-Item Search in Video with the Keyframe Navigation Tree
نویسندگان
چکیده
In this paper we propose the Keyframe Navigation Tree (KNT) as navigational aid in video for interactive search. The KNT is a hierarchical visualization of keyframes that can compactly represent the content of a video with different levels of details. It can be used as an alternative, or in addition, to a common seeker-bar of a video player. Through a user study with 20 participants we show that the proposed navigation approach not only allows significantly faster interactive search in video than a common video player, but also requires significantly less effort (also less mental and physical load) and is much more enjoyable to use.

Hierarchical Navigation and Visual Search for Video Keyframe Retrieval
This work presents a browser that supports two strategies for video browsing: the navigation through visual hierarchies and the retrieval of similar images and objects. The input videos are firstly processed by a keyframe extractor to reduce the temporal redundancy and decrease the number of elements to consider. These generated keyframes are hierarchically clustered with the Hierachical Cellul...
متن کاملHow Do Users Search with Basic HTML5 Video Players?
When searching within a video for a specific scene most nonexpert users employ a basic video player. The main advantage of such a player over more advanced retrieval tools lies in its ease of use and familiar controls and mode of operation. This means that the available navigation controls (play, fast forward, fast reverse, seeker-bar) will be used for interactive search and browsing. We compar...
متن کاملPicSOM Experiments in TRECVID 2010 Workshop draft
Our experiments in TRECVID 2010 include participation in the semantic indexing and known-item search tasks. In the semantic indexing task we implemented SVM-based classifiers on five different low-level visual features extracted from the keyframes. In addition to the main keyframes provided by NIST, we also extracted and analysed additional frames from longer shots. The feature-wise classifiers...

متن کاملA Synergistic Approach to Efficient Interactive Video Retrieval
A video database can contain a large number of videos ranging from several minutes to several hours in length. Typically, it is not sufficient to search just for relevant videos, because the task still remains to find the relevant clip, typically less than one minute of length, within the video. This makes it important to direct the users attention to the most promising material and to indicate...
