Adaptive Switching Median Filter for Impulse Noise Removal Based on Support Vector Machines

A Modified Median Filter for the Removal of Impulse Noise Based on the Support Vector Machines

In this work we present a new approach for the median filter. We modify this nonlinear filter used in impulse noise removal by applying it only to the noisy pixels and by using a different pixel as output of the modified filter. The decision between the noisy and no noisy pixels is implemented by using the Support Vector Machines classification. We use this new classification tool because of it...

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

Improved sorted switching median filter for removal of impulse noise

Digital image processing plays important role in our daily life. Digital Image Processing involves the modification of digital data for improving the image qualities with the aid of computer. The processing helps in maximize the clarity, sharpness of image and details of features of interest. The digital image is given as input into a computer and computer is programmed to change data with the ...

An adaptive dynamically weighted median filter for impulse noise removal

A new impulsive noise removal filter, adaptive dynamically weighted median filter (ADWMF), is proposed. A popular method for removing impulsive noise is a median filter whereas the weighted median filter and center weighted median filter were also investigated. ADWMF is based on weighted median filter. In ADWMF, instead of fixed weights, weightages of the filter are dynamically assigned with th...
