for those who hate preambles

Warning

This presentation is inspired from S.G. Mallat's book and does not pretend to reflect it exactly. It is concerned with the following topics:

The following topics from the book are not covered here:


Proposed Tours

Four tours are proposed, corresponding to four different topics. These tours are linked to each other sequentially. Many links allow navigation from one to topic to another for a nonlinear browsing.


Index

For direct access, here is a list of links that point to the main topics:

Fourier Transform
Instantaneous Frequency of an Analytic Signal
Time-Frequency Localization
Windowed Fourier Transform and Wavelet Transform
Frames and Riesz Bases
Windowed Fourier Frames and Wavelet Frames
Multiresolution Approximations
Wavelet Bases
Filter Banks
Regularity Analysis of a Signal
Detection of Singularities
Reconstruction from Dyadic Maxima
Edge Detection and Image Reconstruction

Algorithms:
Fast Fourier Transforms and Convolutions
Fast Windowed Fourier Transform
Fast Wavelet Transform
Fast Dyadic Wavelet Transform
Decomposition and Reconstruction over Orthonormal Wavelet Bases


Numerical Computations

All numerical figures in the book have been computed using Wavelab, a freeware Matlab Toolbox, available at

http://www-stat.stanford.edu/~wavelab/

Uvi Wave is another freeware Matlab Toolbox.

I have just finished a Matlab Wavelet Tutorial.


Updates:

June 4, 1999: Full Strang and Fix conditions added, with proof!

May 18, 2001: added mathematical transition from filter banks to multiresolution analysis

new January 2008: improved previous connection between discrete and continuous wavelets
