Signal-to-noise ratio enhancement based on wavelet filtering in ultrasonic testing.
In ultrasonic non-destructive testing of materials with a coarse-grained structure the scattering from the grains causes backscattering noise, which masks flaw echoes in the measured signal. Several filtering methods have been proposed for improving the signal-to-noise ratio. In this paper we present a comparative study of methods based on the wavelet transform. Experiments with stationary, dis...
متن کاملImage Denoising based on Adaptive Wavelet Thresholding by using Various Shrinkage Methods under Different Noise Condition
Wavelet transforms enable us to represent signals with a high degree of scarcity. Wavelet thresholding is a signal estimation technique that exploits the capabilities of wavelet transform for signal denoising. The aim of this paper is to study various thresholding techniques such as Sure Shrink, Visu Shrink and Bayes Shrink and determine the best one for image denoising. This paper presents an ...
متن کاملSpeckle Noise Reduction in Ultrasound Images by Wavelet Thresholding
Medical practitioners are increasingly using digital images during disease diagnosis several state-of-the-art medical equipments are producing images of different organs, which are used during various stages of analysis. Examples of such devices include MRI, CT, ultrasound and X-Ray. In medical image processing, image denoising has become a very essential exercise all through the diagnose becau...

متن کاملRobust wavelet thresholding for noise suppression
Approaches to wavelet-based denoising (or signal enhancement) have so far relied on the assumption of normally distributed perturbations. To relax this assumption, which is often violated in practice, we derive a robust wavelet thresholding technique based on theMinimax Description Length principle. We rst determine the least favorable distribution in the "-contaminated normal family as the mem...
