This project has developed a prototypical
digital video library system called VISION (Video Indexing
for SearchIng Over Networks. VISION can digitize, compress, store,
index, search, and retrieve video, audio, and closed-caption information.
We have developed a client and server which can provide video
information over the
Internet or the evolving National Information Infrastructure.
To be an effective library, users need to be
able to find the video segments they want. This project is
conducting ground-breaking research into automatic
content-based segmentation and indexing of videos that will significantly
improve the users' ability to access specific segments of
interest with videos.
Videos, soundtracks and closed-captions are
digitized,
and the video and audio signals are used together to
provide scene-based segmentation rather than pixel-based segmentation.
Information from the closed-captions are used to automatically index
the segments based on their contents.
Together, this allow users to quickly
search indices for multiple videos to locate segments of
interest, and to view and manipulate these segments on their remote computer.
Future work will investigate using soundtrack and
transcripts for further indexing information.
This project is being used to build the video database for
the Digital Jayhawk,
a multimedia collection of news articles and broadcasts created
at the University of Kansas.
