Image Sequence Superresolution--Latest Research Results
Prof. Nirmal K. Bose, Pennsylvania State University, USA

Seminar • 12 July 2004

More Info ...Abstract
Image sequence superresolution algorithms estimate a high-resolution image with finer spectral details from multiple low-resolution observations degraded by blur, noise and undersampling. The major advantage of this approach is practicality and cost reduction by applying technical devices in signal processing and mathematical analysis on the images acquired by a low-resolution imaging system which, possibly, could be a video-camera, a prefabricated multisensor array, a vibrating camera, a low-resolution scanning electron microscope or a matrix of optoelectronic sensors, among others. The dynamism in this area of research is substantiated by not only the voluminous past activity within a reasonably short time span but also the realized need to meet many other remaining challenges. The aim of this seminar is to provide a technical snapshot of developments to date and introduce promising new developments in both the theory and applications of sequence superresolution imaging science and technology, including the most recent use of second generation wavelets for the purpose. About the author:
N.K. Bose is the HRB-Systems Professor of Electrical Engineering and University Endowed Fetter Fellow at The Pennsylvania State University, University Park. He is the author of Applied Multidimensional Systems Theory (New York: Van Nostrand Reinhold, 1982), Digital Filters (Amsterdam, The Netherlands: Elsevier, 1985; Malabar, FL: Krieger, 1993), the main author as well as editor of Multidimensional Systems; Progress, Directions, and Open Problems (Dordrecht, The Netherlands: Reidel, 1985), coauthor of Neural Network Fundamentals with Graphs, Algorithms, and Applications (New York: McGraw-Hill 1996) and Multidimensional Systems Theory and Applications (Dordrecht, The Netherlands: Kluwer Academic Publishers, 2003). He is, since 1990, the founding editor-in-chief of the International Journal on Multidimensional Systems and Signal Processing and and has served on the editorial boards of several other journals.
Professor Bose received several honors and awards, including, more recently, the Invitational Fellowship from the Japan Society for the Promotion of Science in 1999, the Alexander von Humboldt Research Award from Germany in 2000, and the Charles H. Fetter University Endowed Fellowship in Electrial Engineering from 2001-2004.
