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...

For removing salt and pepper noise from corrupted image we are using so many algorithms. In this paper we propose two phase scheme for removing salt and pepper noise and edge preservation; in the first phase Adaptive median filter is used to detect corrupted pixel and preserving the edges. In...
FPGA Implementation of Adaptive Median Filter for the Removal of Impulse Noise Because of its simplicity, this proposed method is suitable to be implemented in consumer electronics products such as digital television, or digital camera Keywords Noise reduction, salt-and-pepper noise,impulse noise, ...
An effective method for salt and pepper noise removal based on algebra and fuzzy logic function Image denoising techniques are very important in modern digital image processing. Many classical denoising algorithms have evolved over the years, such as ... J Gao,L Li,X Ren,... - 《Multimedia ...
In this paper, a novel two-phase modified decision based unsymmetrical trimmed mean filter, for removal of very high density salt and pepper noise (SPN) from images and videos is proposed. The first phase comprises the use of an unsymmetrical trimmed mean filter when the processing window is ...
There is a significant recent advance in filtering of the salt-and-pepper noise for digital images. However, almost all recent schemes for filtering of this type of noise are not taking into an account the shape of objects (in particular edges) in images

With this paper we propose an iterative trimmed median filter and an adaptive window trimmed median filter for effective suppression of salt and pepper noise. The iterative trimmed median filter works in a way that, when a selected neighborhood window of a noise pixel is completely noisy, such ...
