Wavelets and Filter Banks Gilbert Strang, Truong Nguyen
Publisher: Wellesley College

Signal Analysis: Wavelets, Filter Banks, Time-Frequency Transforms and Applications (by Alfred Mertins). A tutorial on filter banks and wavelets. Title: A procedure for designing exact reconstruction filter banks for tree structured subband coders. 2D DWT can be applied as a convolution of a selected wavelet function with an original image or it can be seen as a set of two matrices of filters, row and column one. Almost all practically useful discrete wavelet transforms use discrete-time filterbanks. Research Focus: Perfect reconstruction, critically sampled, two-channel wavelet filterbanks on graphs. Some of the main topics covered include DSP systems, image restoration, z-transform, FIR filters, adaptive filters, wavelets, and filterbanks. The Mallat algorithm is in fact a classical scheme known in the signal processing community as a two-channel subband coder (see page 1 of the book Wavelets and Filter Banks, by Strang and Nguyen [StrN96]). These filter banks are called the wavelet and scaling coefficients in wavelets nomenclature. Signal analysis gives an insight into the properties of signals and stochastic processes by methodology.
