Somantika Datta's April 2011 Talk
Time and Date: 4:10 pm Tuesday, April 5
Location: 5W Neill Hall, WSU Mathematics Department
Title: Redundancy in signal processing: the role of frames
Abstract: Redundancy is a standard tool used in modern signal processing to construct signals that are resilient to noise and transmission losses. Representing a signal in terms of overcomplete sets called frames is how redundancy is attained in signal processing. This talk with give an overview of frame theory, discuss different families of frames and their applications, and indicate some questions/problems that arise in designing frames with certain desirable qualities.
Speaker Bio: Somantika Datta joined the Department of Mathematics at the University of Idaho as an assistant professor in Fall 2010. Earlier she received her Ph.D. from the University of Maryland at College Park after which she spend time as a postdoc in Arizona Sate University and Princeton University. Her research interests include applications of harmonic analysis to problems in signal processing and medical imaging, compressed sensing, and sampling theory.
