Adaptive Filtering Algorithm Using Long-Range Correlation for the Removal of Impulse Noise from Images

Abstract

An adaptive filter using long-range correlation for the removal of impulse noise from images was proposed. Impulse noise was detected by the method of local extremum at first. Then the background mean square error between signal pixels and noise pixels was computed in the definite search range, and the filtering process was going by the adaptive weight… (More)
