A central goal of signal processing is to describe real-time signals, be it for computation, compression, or understanding. This book presents a unified view of wavelets and subband coding with a signal processing perspective. Covers the discrete-time case, or filter banks; development of wavelets; continuous wavelet and local Fourier transforms; efficient algorithms for filter banks and wavelet computations; and signal compression.

Features
provides broad coverage of theory and applications and a different perspective based on signal processing.
gives framework for applications in speech, audio, image and video compression as used in multimedia.
includes sufficient background material so that people without signal processing knowledge will find it useful.
