Abstract

A new method is proposed to eliminate impulsive noise in digital images. The method is based on impulse noise detection by means of a self-organizing neural network and a class of noise-exclusive filters. The filtering scheme presented can suppress impulse noise effectively while preserving image edges and fine details. Experimental results demonstrate that the performance of the noise-exclusive filters is superior to that of the traditional median filter family.
