An Adaptive Non-linear Statistical Salt-and-Pepper Noise Removal Algorithm using Interquartile Range

Abstract

This paper presents a salt-and-pepper noise removal scheme using modified mean filter. The proposed  method  is based on a simple basic concepts of mean filter, where each mean value is calculated from the mathematical formula of interquartile range (IQR). It replaces the noisy pixels using IQR based mathematical formula applied on the filter window.  Experimental results are presented to demonstrate the  efficiency (quality of the image) of the method  compared to other existing different types of impulse noise removal techniques.
