ABSTRACT
An efficient two stage morphological impulse noise detector is proposed in this paper. The proposed method first
identifies the noise pixels by comparing the current pixel with the brightest and the darkest pixels in its working
window and then in second stage morphological operations based detector is used to improve the performance of
impulse noise detector. Simulation results performed on different images shows better results in terms of the qualitative
and quantitative measures of the images.
