Abstract

This book presents a mathematical introduction to the theory of orthogonal wavelets and their uses in analysing functions and function spaces, both in one and in several variables. Starting with a detailed and self contained discussion of the general construction of one dimensional wavelets from multiresolution analysis, the book presents in detail the most important wavelets: spline wavelets, Meyer's wavelets and wavelets with compact support. It then moves to the corresponding multivariable theory and gives genuine multivariable examples. Wavelet decompositions in Lp spaces, Hardy spaces and Besov spaces are discussed and wavelet characterisations of those spaces are provided. Also included are some additional topics like periodic wavelets or wavelets not associated with a multiresolution analysis. This will be an invaluable book for those wishing to learn about the mathematical foundations of wavelets.

Abstract

Ce livre est une introduction à l'analyse des signaux par la technique des ondelettes, méthode qui permet souvent de faire mieux ressortir les caractéristiques des signaux que la traditionnelle décomposition en série de Fourier. Les premiers chapitres consistent en une introduction aux décompositions de types "; temps-fréquence "; des fonctions et des signaux, assortie de quelques exemples simples. Des aspects plus spécifiques sont ensuites traités : l'utilisation des ondelettes pour la caractérisation des singularités dans les fonctions et les signaux – avec une brève incursion dans le monde des fractales –, ainsi que l'analyse temps-fréquence proprement dite, etc. Un troisième volet est consacré au problème de discrétisation des représentations temps- fréquence continues. La dernière partie couvre des aspects plus géométriques. L'ouvrage s'adresse aux étudiants en troisième cycle de physique ou de mathématiques – certains points sont abordables dès le deuxième cycle – et aux élèves des écoles d'ingénieurs. Il intéressera aussi les chercheurs et les ingénieurs ayant à résoudre des problèmes d'analyse et de traitement du signal. L'originalité de son approche est de rassembler en une seule étude les aspects géométriques et algorithmiques du sujet. Il fournit certains algorithmes directement applicables.

Abstract

Today, more sophisticated techniques are necessary for spectral analysis, reconstruction, restoration of signals, their digital and analogic processing, specialized signal diagnostics, and short intervals with occurrences that require greater speed and precision. As the frequency domain of the wavelet transform gets more detailed and considerably more specific in various applications, it necessitates specialized scholarly attention in its many forms and relationships with other transforms with special functions. For example, using the wavelet transform with special functions can prove valuable in creating and designing special signal filters or the interphase between reception-emission devices with specialized sensors for medical use. In quantum phenomena, its corresponding version of the wavelet transform is instrumental in the spectral study of particles and their correlation. Therefore, using specialists' and experts' views, this book delves into an exposition on spectral analysis, restoring, monitoring, and signal processing, as well as essential applications required in waveguides and for the improvement of medical images, proving the wavelet transform to be helpful in resolution analysis in time-frequency, with an emphasis on different methods of the calculus using FFT and DSTFT. This book has been divided into four sections covering all the abovementioned subjects.

Abstract

Wavelets is a carefully organized and edited collection of extended survey papers addressing key topics in the mathematical foundations and applications of wavelet theory. The first part of the book is devoted to the fundamentals of wavelet analysis. The construction of wavelet bases and the fast computation of the wavelet transform in both continuous and discrete settings is covered. The theory of frames, dilation equations, and local Fourier bases are also presented.The second part of the book discusses applications in signal analysis, while the third part covers operator analysis and partial differential equations. Each chapter in these sections provides an up-to-date introduction to such topics as sampling theory, probability and statistics, compression, numerical analysis, turbulence, operator theory, and harmonic analysis.The book is ideal for a general scientific and engineering audience, yet it is mathematically precise. It will be an especially useful reference for harmonic analysts, partial differential equation researchers, signal processing engineers, numerical analysts, fluids researchers, and applied mathematicians.
