Statistical Methods for Compressive Hyperspectral Imaging

With Professor Lawrence Carin, William H. Younger Professor of Engineering, Duke University

Faculty Host: Venkatesh Saligrama

Refreshments will be served outside Room 339 at 3:45 p.m.

Abstract: Many high-dimensional signals or images measured in the natural world are highly compressive. Compressive sensing is motivated by the idea of measuring such data in a new way so that a priori takes account of its compressive nature, thereby substantially reducing the quantity of data that needs be measured in the first place. In this talk, Professor Carin will speak about a new compressive hyperspectral camera developed in collaboration with Professor David Brady of Duke. He will discuss how nonparametric Bayesian methods may be used to process the compressive data measured by such a camera in order to yield high-quality hyperspectral imagery from a quantity of measured data substantially less than that acquired by a traditional camera. He will also discuss how information theory may be used to optimize compressive camera design.

About the Speaker: Lawrence Carin earned the B.S., M.S., and Ph.D. degrees in electrical engineering at the University of Maryland, College Park, in 1985, 1986, and 1989, respectively. In 1989 he
joined the Electrical Engineering Department at Polytechnic University (Brooklyn) as an Assistant Professor and became an Associate Professor there in 1994. In September 1995, he joined the Electrical Engineering Department at Duke University, where he is now the William H. Younger Professor of Engineering and Chairman of the Electrical and Computer Engineering Department. He is a co-founder of Signal Innovations Group, Inc. (SIG), a small business where he serves as the Director of Technology. His current research interests include statistical signal processing, sensing, and machine learning. He is an IEEE Fellow.
