Abstract
Removal of the noise entirely is the most intricate process, as it sometimes ruins the visual excellence of image along with its details. So, the exclusion of noise is imperative for the better quality of images. Noisy pixels also reserves the memory; that space is unnecessary reserved for senseless data. Noise added in an image during image acquisition mostly. In this manuscript, we present an efficient method for removing salt and pepper noise using the modified weighted mean filter. It includes noise identification and removal processes from the Magnetic Resonance Images. And reproduce an enhanced de-noised image. In the proposed method, we use the cosine rule for detecting the noisy pixel and replaced by their mean value within a window size 3\(\times \)3. Similarly, we applied the proposed methods on various filters like alpha trimmed filter, mean, mode and median filter and all the filters give promising results. Experiment results indicate efficiency over other approaches in removing salt-and-pepper noise.
