Cluster Analysis means to collect elements (i.e. pixels) of the same property (in this context this means: gray value) to a cluster. These clusters can be visualized by colorizing them or by reconstructing them to a grayscale picture. We are showing that a cluster analysis can be done directly on picture data (pixels) or on wavelet coefficients resulting from a wavelet analysis of the image. The clustered coefficients then are transformed back using the inverse wavelet tranform. The quality of this reconstruction depends on the used wavelet-transform

Wavelets Wavelet analysis means breaking up a signal into scaled and translated versions of the Wavelets - special functions called mother Wavelets. (Fourier analysis means breaking up a signal into sinusoid functions of different Frequencies) Each wavelet has a special waveform of limited duration and an average value of zero. The Wavelet is scaled to fit the original signal shape. A high scale wavelet (wavelet with high amplitude) is the approximation of the signal – the low Frequency part of the signal. A low scale denotes the details – the high Frequency part of the signal. Figure 4.12 A = original signal B = approximation of the signal – low Frequency part C = details of the signal – high Frequency part – medium scale D = details of the signal – high Frequency part – small scale B, C and D are mother Wavelets with different scale. In wavelet transforms – continuous and discrete, we start with a small scale of the mother wavelet, i.e. the mother Wavelet C in figure 4.12, and continuously translate it along the function. If a section of the original signal is covered by a wavelet, we calculate it as a number - Wavelet coefficient C w . This coefficient explains the quality of the match between the original signal and the mother Wavelet. A high C w represents a great similarity.

WAVELETS e as Artes Multiresolucionárias This Place is under renewing This page in portuguese Conceitos basicos da Teoria Wavelet Wavelets sao nada mais que ondas pequenas ( ondeletes , em frances) com determinadas propriedades que as tornam adequadas a servirem de base para decomposicao de outras funcoes, assim como senos e cossenos servem de base para decomposicoes de Fourier. As origens da teoria Wavelet remontam aos anos 30, quando, ainda sem corpo, podia ser discretamente identificada em trabalhos de Analise Funcional e outros ramos matematicos. Sua emancipacao ocorre nos anos 80, fruto natural de seu uso e aplicacao em prospeccao mineral, analise e tratamento de imagens, etc. A Transformada Wavelet e' uma ferramenta de processamento de sinais que tem um trunfo sobre as tecnicas classicas de Fourier: suas funcoes bases (wavelets) nao pertencem a um espaco finito de solucoes, isto e', existem teoricamente infinitas possibilidades de se projetar wavelets com propriedades especiais, voltadas para aplicacoes especificas. Pode-se projetar wavelets otimizadas para realizar analises especiais, onde as wavelets tenham caracteristicas semelhantes aos sinais sob analise: uma especie de Homeopatia Matematica -a cura pelos semelhantes, a analise pelo "self". Assim, wavelets que sao utilizadas para compressao de dados, podem revelar-se pessimas para aplicacoes de analises de sinais biologicos, ou sintese de musica. Da mesma forma, wavelets para sintese de sons podem nao ser uteis em aplicacoes para compressao de dados.

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.

Nonlinear Multirate Filterbanks Gonzalo R. Arce Neal C. Gallagher Xiang-Gen Xia Publications Multirate filterbanks: Theory and Applications in Wireless Communications - Multipath Intersymbol Interference (ISI) and Interchannel Interference (ICI) Cancellations Multipath ISI/ICI cancelation/equalization is one of the most important problems in communication systems. This research aims to develop new intersymbol interference (ISI) and interchannel interference (ICI) cancellation methods by using pre/post coding via nonmaximally decimated multirate filterbanks. It has been shown that any finite tap ISI that may have spectral-nulls charateristics (or frequency-selective fading that is very common in wireless communication enviroment) can be eliminated completely by using nonmaximally decimated FIR multirate filterbanks in pre/post coding. Moreover it has been shown that the precoding may be independent of the ISI channels and therefore feedback is not necessary. As a special case of the precoding scheme, a rate 1/N precoding is equivalent to a fractionally-spaced equalizer with N time faster sampling rate than the baud rate. In this research, we consider not only ISI but also channel random noise in communication systems as a whole. We combine the multirate filterbank pre/post coding for eliminating ISI and the traditional error protection coding for correcting random errors together to achieve a better peformance than the existing techniques. We also apply the pre/post coding technique to mitigate ICI in multiple user communication systems, such as wireless mobile communication systems.

In this thesis we focus on two applications: image processing and compression to create low-dimensional models for dynamical systems. We worked out the details of integer wavelet transforms, based on the lifting scheme, for a class of biorthogonal wavelets (Cohen-Daubechies-Feauveau). Based on this we designed and implemented a software library called WAILI (Wavelets with Integer Lifting) that provides wavelet transforms and wavelet-based image processing operations on two-dimensional images. Later we added support for very large images and block-based processing.

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.

This document describes and implements several of the most important functions in image processing: discrete wavelet transform, quantization, smoothing. I also propose adding noise to images as to remedy quantization artifacts. All the stuff here is based on the Cohen-Daubechies-Feauveau 9/7 wavelet filter, the standard transform in the JPEG-2000 standard. We implement it with an efficient lifting transformation. Of course, I did not follow the standard, but have attempted to simplify. The core idea of the ennoising strategy is to estimate the amount of quantization noise caused by the quantization in each subband, approximate it with a normally distributed random noise, and re-introduce it during decompression. The result can be seen in the image below. On the left, there is the compressed image, suffering from the blurring artifacts . In the center there is the original image, and on the right there is the compressed image to which Gaussian noise was added to the wavelet coefficients after de-quantization and before IDWT: (images are slightly enlarged) Downloadables: Mathematica 4.0 notebook with images
