We propose a denoising algorithm for medical images based on a combination of the total variation minimization scheme and the wavelet scheme. We show that our scheme offers effective noise removal i...
A Wavelet Packets Approach to Electrocardiograph Baseline Drift Cancellation
Electrocardiograph Baseline Drift Cancellation
2009/9/8
Baseline wander elimination is considered a classical problem. In electrocardiography (ECG) signals, baseline drift can influence the accurate diagnosis of heart disease such as ischemia and arrhythmi...
A critical issue in image restoration is the problem of noise removal while keeping the integrity of relevant image information. The method proposed in this paper is a fully automatic 3D blockwise ver...
A Based Bayesian Wavelet Thresholding Method to Enhance Nuclear Imaging
Enhance Nuclear Imaging Bayesian
2009/9/4
Nuclear images are very often used to study the functionality of some organs. Unfortunately, these images have bad contrast, a weak resolution, and present fluctuations due to the radioactivity disint...
A Wavelet-Based Multiresolution Reconstruction Method for Fluorescent Molecular Tomography
Fluorescent Molecular Tomography Multiresolution
2009/9/4
Image reconstruction of fluorescent molecular tomography (FMT) often involves repeatedly solving large-dimensional matrix equations, which are computationally expensive, especially for the case where ...
