Digital image processing is a subset of the electronic domain wherein the image is converted to an array of small integers, called pixels, representing a physical quantity such as scene radiance, stored in a digital memory, and processed by computer or other digital hardware. The application of median filter has been investigated. As an advanced method compared with standard median filtering, t...

In medical image processing, noise removal is the challenging task. Removal of noise using the existing methods like Median Filter (MF), Center Weighted Median Filter (CWMF), Rank Condition Rank Selection Filter (RCRSF) and SMF Selective Median Filter (SMF) provides satisfactory results. In this paper, we have made improvements in SMF by providing the adaptive thresholding concept and called as...

This paper presents an application of the adaptive median post-filter to improve impedance estimation based on the differential equation algorithm. The main feature of the post-filter is the automatic selection of the optimal window size that balances between fast tracking and filtering performance. For sudden impedance change (fault inception), small window size is selected to make fault detec...

In this paper presents a new algorithm fuzzy based median filter (FBMF) to remove low and high density salt and pepper noise in gray scale Images. Proposed algorithm replaces the noisy pixel by median value when 0’s, 255’s and other pixel values are present in the selected window and when all pixel values are either 0’s or 255’s, or combination of these, then the noise pixel is replaced by fuzz...

Several researchers are concentrated on cancellation of salt and pepper noise from the two-dimensional signals like digital images and uses several filters like mean filter, median filter, trimmed median filter etc. , for removal of noise. A novel approach has been implemented using a filter so called Additive White Median Filter (AWMF) for filtering the two-dimensional signal which uses a sche...
