The Discovering Wavelets Web Site maintained by Edward Aboufadel and Steven Schlicker Our goal for this site is to make it a center of activity for incorporating wavelets into the undergraduate curriculum. We believe that wavelets can be accessible to people other than research mathematicians that anyone with a background in basic linear algebra (for example, graduate and undergraduate students, and nonspecialists) can learn about and work with wavelets. Undergraduates at GVSU, many who are prospective mathematics teachers, have completed projects based on wavelets, along with undergraduate research projects. The challenge to mathematics professors is to present wavelets in way that is accessible without being trivial. New and Noteworthy The REU program will continue in Summer 2004. During Summer 2002, two projects in wavelets were pursued . To learn about the Summer 2003 REU program, go to the GVSU REU web site The new version of the Apple Macintosh operating system (10.3 Panther) includes Pixlet, a wavelet-based codec with some connections to Pixar corporation. According to Apple, "Pixlet is the first studio-grade codec for filmmakers. Pixlet provides 20-25:1 compression, allowing a 75MB/sec series of frames to be delivered in a 3MB/sec movie, similar to DV data rates. Or a series of frames that are over 6GB in size can be contained within a 250MB movie. Pixlet lets high-end digital film frames play in real time with any Panther Mac, without investing in costly, proprietary playback hardware."

Valens, 1999-2004 Sometimes people don't know how to address me when writing me. They call me professor Valens, doctor Valens, mr/miss Valens, Valens or professor Clemens, doctor Clemens, mr/miss Clemens, Clemens, or simply nothing. So then, how should you address me, you wonder? Well, I don't care, but if you must know, I am (a) male. NEW! * I finally invested some time to learn how to make PDF files and updated my wavelet tutorial PDF file * Made it all more printer friendly. Some images were to large to print correctly. * Fixed missing symbols (forgot to transform some GIF files to PNG). * Added little note about two-dimensional transform to the introduction. * New email address. The folks at iName.com now want money so I decided to let good old mindless go. * All GIF files have been replaced by PNG files. These files are a bit smaller than GIF files and so this page should load a bit faster. (Saved over 15KB on this page!) * Added a link to the Wavelet Forum at the end.

We started these m-files when Jean-Marc Lina from University of Montreal was visiting Duke University. At that time JML, being a complex wavelet guru, guided Gaby Katul and me how to do forward complex DISCRETE wavelet transformation. We originally used complex filters from Lina's papers and then discovered that Barry G. Sherlock now at UNC-Charlotte made an m-function a la Donoho's MakeONFilter.m for producing Daubechies complex filters. Getting into the complex wavelet domain was easy compared to returning back to the ``time'' domain. We made an m-file for inverse transformation but it was less than perfect...(a nice way to say it did not work as it was supposed to).

Wavelets Wavelets are a relatively recent arrival on the scene, starting to make their mark in both the mathematical and applied communities in the mid 1980s. They provide an alternative to classical Fourier methods for one- and multi-dimensional data analysis and synthesis, and have numerous applications both within mathematics (e.g., to partial differential operators) and in areas as diverse as physics, seismology, medical imaging, digital image processing, signal processing and computer graphics and video. The most popular and accessible application of wavelets is probably to image compression. Emmy Noether (original, 25 to 1 and 100 to 1 normalized Haar wavelet compressed images). See Matlab M-files if you want to generate similar compression pictures for yourself. Unlike their Fourier cousins, wavelet methods make no assumptions concerning periodicity of the data at hand. As a result, wavelets are particularly suitable for studying data exhibiting sharp changes or even discontinuities. Wavelets allow information to be encoded according to "levels of detail" - in one sense this parallels the way in which we often process information in our everyday lives. Contrary to popular belief, wavelet basics can be explored keeping the mathematical prerequisites to a minimum - namely, familiarity with the elements of linear algebra. In particular, no knowledge of Fourier analysis is necessary to grasp the main concepts. We first became aware of this, in the case of simple Haar wavelets, via the wonderful paper

C ontents Wavelet Overview Wavelet Forum Wavelet Digest Fourier Trivia ... Changes to the Page W avelet Overview The fundamental idea behind wavelets is to analyze according to scale. Indeed, some researchers in the wavelet field feel that, by using wavelets, one is adopting a whole new mindset or perspective in processing data. Wavelets are functions that satisfy certain mathematical requirements and are used in representing data or other functions. This idea is not new. Approximation using superposition of functions has existed since the early 1800's, when Joseph Fourier discovered that he could superpose sines and cosines to represent other functions. However, in wavelet analysis, the scale that one uses in looking at data plays a special role. Wavelet algorithms process data at different scales or resolutions. If we look at a signal with alarge "window," we would notice gross features. Similarly, if we look at a signal with a small "window," we would notice small discontinuities. The result in wavelet analysis is to "see the forest and the trees." Can you see why these features make wavelets interesting and useful? For many decades, scientists have wanted more appropriate functions than the the sines and cosines which comprise the bases of Fourier analysis, to approximate choppy signals. By their definition, these functions are non-local (and stretch out to infinity), and therefore do a very poor job in approximating sharp spikes. But with wavelet analysis, we can use approximating functions that are contained neatly in finite domains. Wavelets are well-suited for approximating data with sharp discontinuities.

Image Compression - from DCT to Wavelets : A Review by Subhasis Saha Introduction Uncompressed multimedia (graphics, audio and video) data requires considerable storage capacity and transmission bandwidth. Despite rapid progress in mass-storage density, processor speeds, and digital communication system performance, demand for data storage capacity and data-transmission bandwidth continues to outstrip the capabilities of available technologies. The recent growth of data intensive multimedia-based web applications have not only sustained the need for more efficient ways to encode signals and images but have made compression of such signals central to storage and communication technology. For still image compression, the `Joint Photographic Experts Group' or JPEG[ ] standard has been established by ISO (International Standards Organization) and IEC (International Electro-Technical Commission). The performance of these coders generally degrades at low bit-rates mainly because of the underlying block-based Discrete Cosine Transform (DCT)[ ] scheme. More recently, the wavelet transform has emerged as a cutting edge technology, within the field of image compression. Wavelet-based coding[
