Fourier Analysis - Dave Rusin; The Mathematical Atlas A short article designed to provide an introduction to Fourier analysis, which studies approximations and decompositions of functions using trigonometric polynomials. Of incalculable value in many applications of analysis, this field has grown to include many specific and powerful results, including convergence criteria, estimates and inequalities, and existence and uniqueness results. Extensions include the theory of singular integrals, Fourier transforms, and the study of the appropriate function spaces. Also approximations by other orthogonal families of functions, including orthogonal polynomials and wavelets. History; applications and related fields and subfields; textbooks, reference works, and tutorials; software and tables; other web sites with this focus. ... Читать дальше »
The amount of wavelets-related software is multiplying!
The "Bath Wavelet Warehouse"
Here is a repository of wavelet filters for you to download and
use. The wavelet file (.wvf), uses an easy to understand format to
describe wavelet filter coefficients. Included are filters for
Biorthogonal wavelets: Bath wavelets ('Bathlets'), UCLA evaluated
wavelets, fingerprint wavelets, modified Coiflet filters;
Orthonormal wavelets: Bath wavelets, Complex Bathlets, Haar wavelet,
Daubechie's wavelets, wavelets to reduce coding artifacts, and other
miscellaneous wavelets.
