Abstract:
The theory and application of signal transforms have influenced broad fields in science, mathematics, and engineering for the past three centuries. Emerging multi-disciplinary research areas have been relying heavily on transforms and spectral analysis more than ever. In this seminar, recent examples of the applications of transforms and spectral analysis will be presented. The focus will be on highlighting the impact of transforms and spectral analysis on two recent areas: Compressed Sensing (CS) and network graphs. Unlike traditional sampling that is based on the legendary Nyquist rate, compressed sensing (or compressive sampling) provides a new framework for capturing signals at lower rates, and hence, opening the door for energy and storage savings for future sensing devices. Compressed sensing has found applications that range from digital imaging to managing routing tables over the Internet. On the other end, transforms are being used to analyze network graphs that capture complex systems. These complex system graphs include wireless sensor networks, the neural network of the human brain, or the massive connections among social network users.
Hayder Radha received the Ph.M. and Ph.D. degrees from Columbia University in 1991 and 1993, the M.S. degree from Purdue University in 1986, and the B.S. degree (with honors) from Michigan State University (MSU) in 1984 (all in electrical engineering). Currently, he is a Professor of Electrical and Computer Engineering (ECE) at MSU and the Director of the Wireless and Video Communications Laboratory. Professor Radha was with Philips Research (1996-2000), where he worked as a Principal Member of Research Staff and then as a Consulting Scientist in the Video Communications Research Department. He was a Member of Technical Staff at Bell Laboratories where he worked between 1986 and 1996 in the areas of digital communications, image processing, and broadband multimedia.
Professor Radha is a Fellow of the IEEE, and he was appointed as a Philips Research Fellow in 2000 and a Bell Labs’ Distinguished Member of Technical Staff in 1992. He is an elected member of the IEEE Technical Committee on Image, Video, and Multidimensional Signal Processing (IVMSP) and the IEEE Technical Committee on Multimedia Signal Processing (MMSP). He served as Co-Chair and Editor of a Video Coding Experts Group of the International Telecommunications Union – Telecommunications Section (ITU-T) between 1994-1996. He served on the Editorial Board of IEEE Transactions on Multimedia and the Journal on Advances in Multimedia. He also served as a Guest Editor for the special issue on Network-Aware Multimedia Processing and Communications of the IEEE Journal on Selected Topics in Signal Processing. Professor Radha is a recipient of the Bell Labs Distinguished Member of Technical Staff Award, the AT&T Bell Labs Ambassador Award, AT&T Circle of Excellence Award, the MSU College of Engineering Withrow Distinguished Scholar Award for outstanding contributions to engineering, and the Microsoft Research Content and Curriculum Award. His current research areas include multimedia communications and coding, image processing, compressed sensing, social networks, sensor networks, and network coding. He has more than 150 peer-reviewed papers and 30 US patents in these areas.
