Estimation-Quantization Geometry Coding Using Normal Meshes
(2003-03-01)
We propose a new algorithm for compressing three-dimensional triangular mesh data used for representing surfaces. We apply the Estimation-Quantization (EQ) algorithm originally designed for still image compression to the ...
Distributed Wavelet Transform for Irregular Sensor Network Grids
(2005-07-01)
Wavelet-based distributed data processing holds much promise for sensor networks; however, irregular sensor node placement precludes the direct application of standard wavelet techniques.
In this paper, we develop a new ...
Multiscale Likelihood Analysis and Image Reconstruction
(2003-08-20)
The nonparametric multiscale polynomial and platelet methods presented here are powerful new tools for signal and image denoising and reconstruction. Unlike traditional wavelet-based multiscale methods, these methods are ...
Diverging moments and parameter estimation
(2004-01-15)
Heavy tailed distributions enjoy increased popularity and become more readily applicable as the arsenal of analytical and numerical tools grows. They play key roles in modeling approaches in networking, finance, hydrology ...
A New Framework for Complex Wavelet Transforms
(2003-06-20)
Although the Discrete Wavelet Transform (DWT) is a powerful tool for signal and image processing, it has three serious disadvantages: shift sensitivity, poor directionality and lack of phase information. To overcome these ...
Unsupervised SAR Image Segmentation using Recursive Partitioning
(2000-04-01)
We present a new approach to SAR image segmentation based on a Poisson approximation to the SAR amplitude image. It has been established that SAR amplitude images are well approximated using Rayleigh distributions. We show ...
Wavelet-based deconvolution for ill-Conditioned systems
(2000-05-20)
This thesis proposes a new approach to wavelet-based image deconvolution that comprises Fourier-domain system inversion followed by wavelet-domain noise suppression. In contrast to other wavelet-based deconvolution approaches, ...
A Geometric Hidden Markov Tree Wavelet Model
(2003-08-01)
In the last few years, it has become apparent that traditional wavelet-based image processing algorithms and models have significant shortcomings in their treatment of edge contours. The standard modeling paradigm exploits ...
Hidden Markov Tree Modeling of Complex Wavelet Transforms
(2000-06-01)
Multiresolution signal and image models such as the hidden Markov tree aim to capture the statistical structure of smooth and singular (edgy) regions. Unfortunately, models based on the orthogonal wavelet transform suffer ...
Multiscale Classification using Complex Wavelets and Hidden Markov Tree Models
(2000-09-01)
Multiresolution signal and image models such as the hidden Markov tree (HMT) aim to capture the statistical structure of smooth and singular (textured and edgy) regions. Unfortunately, models based on the orthogonalwavelet ...
