BOESZOERMENYI L.: Video browsing using interactive navigation summaries

A new approach for interactive video browsing is de-scribed. The novelty of the proposed approach is the flexi-ble concept of interactive navigation summaries. Similar to time sliders, commonly used with standard soft video play-ers, navigation summaries allow random access to a video. In addition, they also provide abstract visualizations of the content at a user-defined level of detail and, thus, quickly communicate content characteristics to the user. Naviga-tion summaries can provide visual information about both low-level features but even high-level features. The concept fully integrates the user, who knows best which navigation summary at which level of detail could be most beneficial for his/her current video browsing task, and provide him/her a flexible set of navigation means. A first user study has shown that our approach can significantly outperform stan-dard soft video players- the state-of-the art ”poor man’s” video browsing tool. 1
