A simple algorithm for spectral line deconvolution
نویسنده
چکیده
The objective of this work is to develop a numerical procedure to subtract the instrumental function from a measured spectral line pro0le. The measuring device (for example, a Fabry–Perot Interferometer) distorts the spectral line pro0le and the experimentally measured one is a convolution of this pro0le and the instrumental function. Restoring the spectral line pro0le is strongly a5ected by numerical instabilities and the problem has been overcome by using the Tikhonov regularization method. The approach is very simple and easy for programming and it is particularly useful for “noisy” experimental data. ? 2001 Elsevier Science Ltd. All rights reserved.

A Sparse Spectral Deconvolution Algorithm for Non-cartesian Mrsi
Purpose: To minimize line shape distortions and spectral leakage artifacts in MR spectroscopic imaging. Methods: A spatially and spectrally regularized non-Cartesian MRSI algorithm that uses the line shape distortion priors, estimated from water reference data, to deconvolve the spectra is introduced. Sparse spectral regularization is used to minimize noise amplification associated with deconvo...
متن کاملEvaluation of Hemodynamic Response Function in Vision and Motor Brain Regions for the Young and Elderly Adults
Introduction: Prior studies comparing Hemodynamic Response Function (HRF) in the young and elderly adults based on fMRI data have reported inconsistent findings for brain vision and motor regions in healthy aging. It is shown that the averaging method employed in all previous works has caused this inconsistency. The averaging is so sensitive to outliers and noise. However, fMRI data are o...

متن کاملPSO-Optimized Blind Image Deconvolution for Improved Detectability in Poor Visual Conditions
Abstract: Image restoration is a critical step in many vision applications. Due to the poor quality of Passive Millimeter Wave (PMMW) images, especially in marine and underwater environment, developing strong algorithms for the restoration of these images is of primary importance. In addition, little information about image degradation process, which is referred to as Point Spread Function (PSF...
متن کاملLow-Rank Spectral Optimization via Gauge Duality
Various applications in signal processing and machine learning give rise to highly structured spectral optimization problems characterized by low-rank solutions. Two important examples that motivate this work are optimization problems from phase retrieval and from blind deconvolution, which are designed to yield rank-1 solutions. An algorithm is described that is based on solving a certain cons...
