An Efficient Additive White Median Filtering for Removal of Salt and Pepper Noise based on Images
R. Priyanka, B. Sirisha · 2014
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 schematic procedure where mean value of the particular window size is used instead of median value for the removal of high density noise from the signals without changing the clarity of the digital image. In this scheme noisy pixels are replaced with the neighborhood non noisy pixels mean value. Whenever the window selected dynamically is non-flexible with the corrupted pixels, then the size of the window is increased in order to flexible with
