"Mobile Visual Search"


Handheld mobile devices, such as camera phones or PDAs, are expected to become ubiquitous platforms for visual search and mobile augmented reality applications. A visual database for mobile image matching is typically stored in the cloud. Hence, for a visual comparison, information must be either uploaded from the mobile to the server, or downloaded from the server to the mobile. With relatively slow wireless links, the response time of the system critically depends on how much information must be transferred in both directions. We review recent advances in mobile matching, using a "bag-of-visual-words" approach with robust feature descriptors, and show that dramatic speed-ups are possible by considering recognition and compression jointly. We will use real-time implementations for different example applications, such as recognition of landmarks or media covers, to show the benefit from image processing on the phone, the server, and/or both.


Bernd Girod is Professor of Electrical Engineering and (by courtesy) Computer Science in the Information Systems Laboratory of Stanford University, California, since 1999. Previously, he was Professor of Telecommunications in the Electrical Engineering Department of the University of Erlangen-Nuremberg. His current research interests are in the areas of video compression and networked media systems. He has published over 400 conference and journal papers, as well as 5 books, receiving the EURASIP Signal Processing Best Paper Award in 2002, the IEEE Multimedia Communication Best Paper Award in 2007, the EURASIP Image Communication Best Paper Award in 2008, as well as the the EURASIP Technical Achievement Award in 2004. As an entrepreneur, Professor Girod has been involved with several startup ventures as founder, director, investor, or advisor, among them Polycom (Nasdaq:PLCM), Vivo Software, 8x8 (Nasdaq: EGHT), and RealNetworks (Nasdaq: RNWK). He received an Engineering Doctorate from University of Hannover, Germany, and an M.S. Degree from Georgia Institute of Technology. Prof. Girod is a Fellow of the IEEE, a EURASIP Fellow, and a member of the German National Academy of Sciences (Leopoldina).
