April 27th Refreshments. St. Thomas 414 Dr. Berger is an Associate Professor in the Department of Physics at the University of Scranton. The subject of wavelets is a beautiful combination of mathematical analysis and signal processing applications. Any signal can be decomposed into a sum of these small, overlapping waves. It offers a new way of analyzing, storing and transmitting information.
Wavelets have remarkable properties.
They are localized waves. Instead of oscillating forever, they drop to zero, and because of the repeated rescaling that produces them, wavelets decompose a signal into details at all scales. This natural multiresolution finds important application in representation and compression of images. This lecture is intended for a general mathematics audience. Seating is limited.
