Built upon the Phase I project, the Phase II project will appropriately serve the purpose of producing a well defined deliverable product or process of digital video database systems based on multiple modalaties of information. The Phase II project will emphasize the commercialization of this product by adding commercial database support system security, and billing system to its functionality and making it robust, efficient, and user-friendly. The Phase II effort will also continue to perform research topics in the fields that have prominent potential such as novel algorithms for segmented video of different applications such as long shots without cuts; discovery of logical structures of video programs including making Scene Transition Graph (STG) components indexable and retrievable; indexing digital video with semantic features including motion analysis, face recognition, object identification, background recognition, speaker identification, human body counting, etc.; mythologies for incorporating annotations in video and copyright protection; using audio and closed captioning information to assist content-based image query; and using special effects, music, and sound as features for indexing and retrieval. This research effort will greatly enhance the capabilities of our digital video database system. Completion of these efforts will add a new set of tools for manipulating digital video contents, thus making it a real commercial product capable of satisfying sophisticated requirements from a different customers with different applications requirements.
