Title: Video Indexing and Summarization using the MPEG-7 Motion Activity Descriptor

Speaker: Ajay Divakaran

Time: January 2002

Venue: Burchard 213

Abstract:

MPEG-7 or "Multimedia Content Description Interface" is a recently proposed standard that will enable content based browsing of multimedia databases much as text is browsed on the world wide web today. We present the MPEG-7 motion activity descriptor, our invention, and its applications. The descriptor can be extracted in the compressed domain and is compact, hence is easy to extract and match. It captures the gross motion characteristics of a video segment in a compact form. It enables effective indexing of video by itself and in combination with other features. We will describe a video summarization technique based on motion activity. Finally, we will demonstrate an application of our work to rapid video browsing.

Ajay Divakaran received the B.E. (with Hons.) degree in Electronics and Communication Engineering from the University of Jodhpur, Jodhpur, India, in 1985, and the M.S. and Ph.D. degrees from Rensselaer Polytechnic Institute, Troy, NY in 1988 and 1993 respectively.He was an Assistant Professor with the Department of Electronics and Communications Engineering, University of Jodhpur, Jodhpur, India from September 1985 to May 1986. He was a Research Associate at the Department of Electrical Communication Engineering, Indian Institute of Science, Bangalore, India from September 1994 to February 1995. He was a Scientist with Iterated Systems Inc., Atlanta, GA from February 1995 to January 1998. Since January 1998, he has been a Principal Member of Technical Staff at the Mitsubishi Electric Research Laboratory, Murray Hill, NJ. His research interests include data compression and transmission with current emphasis on video compression and indexing. He has been an active contributor to the MPEG-7 video standard.
