Ten Lectures on Wavelets Ingrid Daubechies CBMS-NSF Regional Conference Series in Applied Mathematics 61 ". . . this is a clearly written introduction to the mathematics of wavelets that provides solid background material on most of the major aspects of the current theory. Especially appealing is the way in which the relationships between wavelets and other areas are pointed out. . . . I feel certain that this will be the major introductory text on wavelets for some time to come. It will definitely be a welcome addition to the library of anyone interested in learning the basics of wavelets." Christopher Heil, SIAM Review, Vol. 35, No. 4, December, 1993. "This book is both a tutorial on wavelets and a review of the most advanced research in this domain...it also gives many practical examples and describes several applications (in particular, in signal processing, image coding and numerical analysis.)" Albert Cohen (Paris), Mathematical Reviews, Issue 93e Ten Lectures on Wavelets "The book by Daubechies, who is one of the main developers of the (wavelet) theory, is the result of an intensive short course. The presentation is completely engrossing; it is like reading a good, thick Russian novel. Daubechies has a real knack for making the material appealing and lively, and there is a definite 'slowing down for details' at the points that require further elucidation . . . This book can be used for many different purposes, from individual reading to graduate-level course-work, and it will likely become a classic." F. Alberto Grunbaum, Science, August 7, 1992.

Wavelets Research Assistant Professor of Computer Science California Institute of Technology Second Generation Wavelets Wavelets have proven to be powerful tools for many signal processing tasks as well as numerical computations. However, classical constructions have been limited to simple domains and regular settings (e.g., regularly spaced samples and product domains). Many practical applications in computer graphics-and engineering in general-require more flexible constructions. These need to accomodate Irregular subdivisions to facilitate optimal hierarchical representations of complex geometry; Adaptive subdivisions to support flexible decomposition of operators and optimal non-linear approximation of functions; Weighted measures to account for complex geometry and to remove singularities; Geometry dependent constraints such as domain boundaries, edges, and corners; Data dependent constraints such as discontinuities, locally exact reconstruction, and algebraic singularities. Classical construction methods for wavelets fail in these settings and new techniques such as lifting need to be employed. Aside from the practical aspects of data structures and fast algorithms many deep mathematical questions need to be answered before these techniques will become widely availalble.

References and Related Links Introduction Wavelets, with their roots in signal processing and harmonic analysis, have had a significant impact in several areas of computer science. They have led to a number of efficient and easy to implement algorithms for use in such fields as: Image Compression and Processing; Global Illumination; Hierarchical Modeling; Animation; Volume Rendering and Processing; Multiresolution Painting; Image Query. The development of wavelets has been motivated primarily by the need for fast algorithms to compute compact representations of functions and data sets. They exploit the structure (if any) in the data or underlying function, reorganizing the same in a hierarchical fashion.

Wavelets in Multiresolution Analysis Presented 2/15/99 for CS563 by Tom Germano Table of Contents Introduction Linear Algebra Review Concepts of Multiresolution Analysis The Haar Wavelet ... Links Introduction In signal analysis, there are a number of different functions one can perform on that signal in order to translate it into different forms that are more suitable for different applications. The most popular function is the Fourier transform that converts a signal from time versus amplitude to frequency versus amplitude. This transform is useful for many applications, but it is not based in time. To combat this problem, mathematicians came up with the short term Fourier transform which can convert a signal to frequency versus time. Unfortunately, this transform also has its shortcomings mostly that it cannot get decent resolutions for both high and low frequencies at the same time. So how can a signal be converted and manipulated while keeping resolution across the entire signal and still be based in time? This is where wavelets come into play. Wavelets are finite windows through which the signal can be viewed. In order to move the window about the length of the signal, the wavelets can be translated about time in addition to being compressed and widened. Linear Algebra Review Unfortunately in order to understand the wavelets, you must understand linear algebra because wavelets make use of vector spaces and matrices quite a lot. Matrices are pretty straight forward and all their functions are covered by using Maple so I won’t bother going over them, instead below I have written a brief introduction to the terms and functions of vectors spaces.

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.

Baraniuk Abstract: We examine the central issues of invertibility, stability, artifacts, and frequency-domain characteristics in the construction of non-linear analogs of the wavelet transform. The lifting framework for wavelet construction motivates our analysis and provides new insight into the problem. We describe a new type of non-linearity for use in constructing non-linear transforms: a set of linear predictors that are chosen adaptively using a non-linear selection function. We also describe how earlier families of non-linear filter banks can be extended through the use of prediction functions operating on a causal neighborhood. We present preliminary results for a synthetic test image. Status: Proceedings of the 31st Asilomar Conference on Signals, Systems, and Computers, Volume 1, pp 662-667, 1997.

Back to home page Diffusion Wavelets Overview Diffusion wavelets generalize classical wavelets, allowing for multiscale analysis on general structures, such as manifolds, graphs and point clouds in Euclidean space. They allow to perform signal processing tasks on functions on these spaces. This has several applications. The ones we are currently focusing on arise in the study of data sets which can be modeled as graphs, and one is interested in learning functions on such graphs. For example we can consider a graph whose vertices are proteins, the edges connect interacting proteins, and the function on the graph labels a functionality of the protein. Or each vertex could be an image (e.g. a handwirtten digit), the edge connect very similar images, and the function at each vertex is the value of digit represented by that vertex. In classical, one-dimensional wavelet theory one applies dilations by powers of 2 and translations by integers to a mother wavelet, and obtains orthonormal wavelet bases. The classical construction has been of course generalized in many ways, considering wide groups of transformations, spaces different from the real line, such as higher-dimensional Euclidean spaces, Lie groups, etc...Most of these constructions are based on groups of geometrical transformations of the space, that are then applied (as a "change of variable") to functions on that space to obtain wavelets.
