A Study on Removing Impulse Noise using Modified Adaptive Switching Median Filter

Improved Adaptive Median Filter Algorithm for Removing Impulse Noise from Grayscale Images

Digital image is often degraded by many kinds of noise during the process of acquisition and transmission. To make subsequent processing more convenient, it is necessary to decrease the effect of noise. There are many kinds of noises in image, which mainly include salt and pepper noise and Gaussian noise. This paper focuses on median filters to remove the salt and pepper noise. After summarizin...

A Switching Weighted Adaptive Median Filter for Impulse Noise Removal

Images are often corrupted by impulse noise due to a noisy sensor or channel transmission errors. The goal of impulse noise removal is to suppress the noise by preserving the integrity of edges and detail information. In this paper, a new filter called Switching Weighted Adaptive Median (SWAM) filter is proposed for effective suppression of impulse noise which is used to incorporate the Recursi...

A Switching Weighted Adaptive Median Filter for Impulse Noise Removal

Impulse Noise Removal with Modified BDND and Adaptive Switching Median Filter

In this paper, a impulse noise removal approach is proposed where a modified boundary discrimative noise detection (MBDND) and an adaptive switching median filter (ASMF) are applied. Note that the BDND has difficulty in cases with high noise densities. A boundary resetting scheme is introduced in the BDND. By this doing, the problem of miss detection in the high noise density is prevented. Note...

Impulse Noise Removal Using Fuzzy Switching Median Filter

Elimination of noise is a necessary and challengeable operation in image processing. Before performing any operation, images have to be first restored. Images are corrupted by noise during image acquirement and transmission. Noise and blurring effects always corrupts any recorded image. To reduce the impulse noise level in digital images a novel algorithm FSM(Fuzzy Switching Median) filter is p...
