Algorithms for Daubechies Waveletsich exhibit jump discontinuities, Daubechies wavelets are continuous. As a consequence of their continuity, Daubechies wavelets approximate continuous signals more accurately with fewer wavelets than do Haar’s wavelets, but at the cost of intricate algorithms based upon a sophisticated theory.

Haar’s Simple Wavelets wavelets” since Haar’s publication in 1910 (reference [19] in the bibliography). To analyze and synthesize a signal—which can be any array of data—in terms of simple wavelets, this chapter employs shifts and dilations of mathematical functions, but does . involve either calculus or linear algebra.

Discrete and Fast Fourier Transformserpolates finite sequences of numbers by Fourier Series. The Fast Fourier Transform provides a comparison and contrast with the Fast Haar and Daubechies Wavelet Transforms in a context that involves complex exponentials and some linear algebra but that does not yet require calculus.

Multidimensional Wavelets and Applicationsots, or geographical measurements. Some of the logical derivations involve matrix algebra. For two-dimensional wavelets, encodings can consist of matrices, indexed by rows from top to bottom, and by columns from left to right. Corresponding to the index of the rows, the . coordinate axis runs . simi

Fourier Transforms on the Line and in Spaceogonal wavelets. The principal use of the Fourier transform in the design of wavelets will consist in transforming “convolutions” of functions into ordinary multiplications of functions, which allow for an analysis easier than with convolutions. The material presented here involves mostly calculus,
