This review article provides a comprehensive survey on state-of-the-art impulse and
Gaussian denoising filters applied to images and summarizes the progress that has been …

In this paper, we proposed a new method, Different Applied Median Filter (DAMF), to remove
salt and pepper (SAP) noise at all densities. We then explained some basic notions of it …

Noise may occur in an image during the image acquisition process. In most of the cases,
during acquisition process in industrial automation, the SPN may affects surface image. For …

We propose an Iterative Mean Filter (IMF) to eliminate the salt-and-pepper noise. IMF uses
the mean of gray values of noise-free pixels in a fixed-size window. Unlike other nonlinear …

Joint sparse representation (JSR) has shown great potential in various image processing
and computer vision tasks. Nevertheless, the conventional JSR is fragile to outliers. In this …

This paper proposes a novel adaptive Type-2 fuzzy filter for removing salt and pepper noise
from the images. The filter removes noise in two steps. In the first step, the pixels are …

In this paper, we deliver a new method to remove salt and pepper noise, which we refer to
as based on pixel density filter (BPDF). The first step of the method is to determine whether …

The most vital challenge for a radiologist is locating the brain tumors in the earlier stage. As
the brain tumor grows rapidly, doubling its actual size in about twenty-five days. If not dealt …

A decision based asymmetrically trimmed Winsorized median for the removal of salt and
pepper noise in images and videos is proposed. The proposed filter initially classifies the …

An adaptive decision based kriging interpolation technique for the removal of high density
salt and pepper noise in images is proposed. The algorithm isolates the non noisy pixels …
