General Content-Based Image Retrieval (CBIR)
Object-Based Image Retrieval
Example – Query by two objects
Techniques used: Image segmentation Neural network Multiple instance
learning …
Research Issues …
Multiple object retrieval for image databases Learning of composite model Information fusion
Apply the developed techniques to other applications such as drug activity discovery, pattern recognition for medical image analysis, etc.
Video Data Mining
Example: Locate the interesting events (goals, corner kicks,
etc.) in a large amount of raw, unprocessed soccer videos
Facilitate automatic annotation and indexing of the high-level structures of soccer videos
Soccer videos

Research Issues …
Video event mining: Detect other types of soccer events like free kick
s, referees, and fouls, etc. Discover the underlying associations among diffe
rent events/subevents Develop a scalable soccer video database syste
m and a flexible user query interface Apply to other types of videos (TV news, Basket
ball, etc.)
