To improve the performance of salt-and-pepper noise removal,a two-stage scheme is proposed.In the first phase,an improved adaptive median filter is used to identify pixels which are likely to be contaminated by noise(noise candidates).In the second phase,the image is restored using a variation...
There has recently been considerable interest in applying total variation regularization with an lscr1 data fidelity term to the denoising of images subject to salt and pepper noise, but the extension of this formulation to more general problems, such as deconvolution, has received little attention....
Utilizing local Hölder seminorm and nonlocal operator, we propose two efficient salt-and-pepper noise removal algorithms in this paper. We first minimize a local Hölder seminorm based functional which has a great capacity to restore natural images. Then by the definition of nonlocal operator...
This paper presents a new class of algorithms based on Youden designs to detect and restore edges present in an image imbedded by mixture or "salt and pepper" noise. The mixture noise consists of a uncorrelated or correlated noisy background plus uncorrelated impulsive noise. The objective is to...
In this paper, we propose a new method for Salt-and-Pepper noise removal from images. Whereas most of the existing methods are based on Ordered Statistics filters, our method is based on the growing theory of Sparse Signal Processing. In other words, we convert the problem of denoising into...
