PRODUCTS Mathematica Mathematica Home Edition Mathematica for Students ... Give us feedback Sign up for our newsletter: New Generation Signal and Image Analysis Discover the power of wavelets! Wavelet analysis, in contrast to Fourier analysis, uses approximating functions that are localized in both time and frequency space. It is this unique characteristic that makes wavelets particularly useful, for example, in approximating data with sharp discontinuities. Engineers, physicists, astronomers, geologists, medical researchers, and others explore the extraordinary array of potential applications of wavelet analysis. Ranging from signal and image processing to data analysis, Wavelet Explorer brings this broad spectrum of wavelet analysis tools to your desktop. Wavelet Explorer 's ready-to-use functions and utilities let you apply a variety of wavelet transforms to your projects. Generate commonly used filters such as the Daubechies' extremal phase and least asymmetric filters, coiflets, spline filters, and more. Visualize wavelets and wavelet packets and zoom in on their details. You can transform your data to a host of wavelet bases, wavelet packet bases, or local trigonometric bases and do inverse transforms in one and two dimensions. Then view the transform in time-frequency space, selecting different bases and boundary conditions. Data compression and denoising are surprisingly simple procedures with Wavelet Explorer 's built-in functions.

Unsourced material may be challenged and removed (August 2009) Daubechies 20 2-d wavelet (Wavelet Fn X Scaling Fn) Named after Ingrid Daubechies , the Daubechies wavelets are a family of orthogonal wavelets defining a discrete wavelet transform and characterized by a maximal number of vanishing moments for some given support. With each wavelet type of this class, there is a scaling function (also called father wavelet) which generates an orthogonal multiresolution analysis. Contents Properties Construction The scaling sequences of lowest approximation order Implementation ... edit Properties In general the Daubechies wavelets are chosen to have the highest number A of vanishing moments, (this does not imply the best smoothness) for given support width N=2A , and among the 2 A possible solutions the one is chosen whose scaling filter has extremal phase. The wavelet transform is also easy to put into practice using the fast wavelet transform . Daubechies wavelets are widely used in solving a broad range of problems, e.g. self-similarity properties of a signal or

W AVELETS FOR C OMPUTER G RAPHICS A P RIMER Eric J. Stollnitz Tony D. DeRose David H. Salesin Wavelets are a mathematical tool for hierarchically decomposing functions. Using wavelets, a function can be described in terms of a coarse overall shape, plus details that range from broad to narrow. Regardless of whether the function of interest is an image, a curve, or a surface, wavelets provide an elegant technique for representing the levels of detail present. This primer is intended to provide those working in computer graphics with some intuition for what wavelets are, as well as to present the mathematical foundations necessary for studying and using them. In Part 1, we discuss the simple case of Haar wavelets in one and two dimensions, and show how they can be used for image compression. Part 2 presents the mathematical theory of multiresolution analysis, develops bounded-interval spline wavelets, and describes their use in multiresolution curve and surface editing. Part 1 Eric J.

Wavelets in Java This web page publishes the Java source code and Javadoc generated documentation for wavelets. Wavelets are a technique, like Fourier analysis, for analyzing signals. They are also used for data compression, comparision and a variety of other applications. I am not a member of the Java cult. Java does not change everything. Java is just a programming language and in many cases, because it is interpreted, a slow one at that. I implemented the wavelet code in Java because I wanted to keep my Java "chops up". I use C++ at work and implement a lot of my own software in C++, so this is a way of sharpening my Java skills. I have a love/hate relationship with C++, but the more I use Java the more sure I am that I've made the right choice in implementing large software components in C++. The UNIX tar program Most of the Java code that implements the wavelet software is packaged with an archive program called tar . The tar program is standard on UNIX, Linux and probably Mac OS X. Originally tar stood for tape archive . If you don't have a copy of tar for Windows NT you can download the win32 binary here . This version of tar is open source software, from Cygnus (now Red Hat), and came with the Cygwin32 package.

35. Wavelets And Signal Processing The grains of understanding that I have gathered regarding wavelets has come from reading several books and a number of journal articles. http://www.bearcave.com/misl/misl_tech/wavelets/index.html

Wavelets and Signal Processing It's true that the Torah the visible Torah, that is is only one of the possible permutations of the letters of the eternal Torah, as God crated it and delivered it to the angels. By rearranging the letters of the book over the centuries, we may someday arrive again at the original Torah. But the important thing is not the finding, it is the seeking, it is the devotion with which one spins the wheel of the prayer and scripture, discovering the truth little by little. Diotallevi in Foucault's Pendulum , by Umberto Eco Using the quote above is, perhaps, ironic, since the character, Diotallevi, in Umberto Eco's Foucault's Pendulum , goes on in the next sentence to denounce the use of computers as tools for seeking truth. Signal processing and filtering is, in its modest way, an attempt to find a better form for a set of information, either by reshaping it or filtering out selected parts (parts that are sometimes labeled as noise). Put another way, signal processing allows us to uncover a form of the signal that is closer to the truth (or a truth). Although we have powerful computing and mathematical tools, perhaps there is some value in taking Diotellevi warning to heart:

Algebra Applied Mathematics Calculus and Analysis Discrete Mathematics ... Interactive Demonstrations Wavelet Wavelets are a class of a functions used to localize a given function in both space and scaling. A family of wavelets can be constructed from a function , sometimes known as a "mother wavelet," which is confined in a finite interval. "Daughter wavelets" are then formed by translation ( ) and contraction ( ). Wavelets are especially useful for compressing image data, since a wavelet transform has properties which are in some ways superior to a conventional Fourier transform An individual wavelet can be defined by Then and gives A common type of wavelet is defined using Haar functions The Season 1 episode " Counterfeit Reality " (2005) of the television crime drama features wavelets.

Wavelets Theory The research on this topic has once again reminded us of the tremendous mathematical complexity behind data compression and transmission. Developed independently in the fields of mathematics, quantum physics, electrical engineering, and seismic geology, the theory of wavelets has already found applications in image compression, vision analysis, and earthquake prediction. Understanding how it works in lay terms, however, is quite difficult. Mathematical Transformation There are currently many applications for transformation functions. Two examples are: Frequency Filtering Because an FT allows a signal to be analyzed in the frequency domain, it is possible to block certain frequencies within a signal, while leaving others. As a signal comes in, it is transformed via an FT, certain component frequencies are removed, and then it is inverse FT'd back to the time domain. Industry applications include filtering data in geologic seismic analysis, and filtering known frequencies of noise from wireless signals. However, due to a phenomenon known as aliasing, the sample rate of this procedure is limited, limiting its precision.
