PanoramaSeek: intelligent streaming for Internet video retrieval

In this paper, we present "PanoramaSeek", a new video streaming system suitable for Internet video retrieval. The system features intelligent streaming, which enables users to take quick glances at arbitrary portions of a video sequence by using slide bars. The streaming system utilizes multi-level interactive streaming and content-based selection of key frames. Multi-level interactive streaming supports three levels of display on a video window: key frame display, normal playback, and specific frame display. Users can switch between levels at any time. Content-based selection of key frames defines key frames by analyzing the changes occurring in video sequences and selecting appropriate, representative frames. Our evaluation of the system demonstrated that multi-level interactive streaming is effective in providing users with random browsing capability, and that content-based selection of key frames improves the efficiency of video retrieval by reducing the number of frames users have to check.© (2003) COPYRIGHT SPIE--The International Society for Optical Engineering.
