The emergence of digital multimedia databases creates a strong drive for fast
and efficient methods for browsing through image and video clip collections.
The Internet and the coming age of digital television intensify the urgency to
properly manage video-centric assets.  In this environment, content creators,
broadcasters, and consumers will rapidly encounter the limitations of
traditional annotation and keyword-based retrieval. In this talk, I will give
an overview of content-based image/video search and browsing and the new ISO
standard, MPEG-7, that is being developed for content description. I will
present few of the algorithms that I have developed for retrieval,
identification and browsing. 

For retrieval, I will present a color based image retrieval algorithm. The
algorithm is scalable and enables search and browsing through large collections
of images and has already been adopted by MPEG-7. For identification, I will
present an algorithm that identifies content based on signatures and has been
used for video authentication with the advantage of being robust to
non-malicious changes. I will also present an algorithm for detecting faces
form color images, and conclude with a mockup demo that illustrates the use of
these technologies in a complete system.
