Abstract

The efficient numerical representation of signals (or functions) is a subject with many applications in engineering, physics, and mathematics. This talk will discuss the approximation of functions from the point of view of "second-generation" wavelet theory. The second-generation theory breaks free of the first-generation theory's reliance on Fourier methods. As a consequence wavelet analysis is possible in situations where Fourier methods are inapplicable, or inconvenient. Applications to compression, modulation, and computer graphics will be discussed briefly. No prior familiarity with the subject will be assumed.
