Abstract

A novel method for the removal of impulse noise from digital images is introduced. In proposed filter, threshold is computed locally from image pixels intensity values in a window and a detail preserving noise filter. Initially, detection phase classifies any possible impulsive noise pixels. Subsequently, the filtering phase replaces the detected noise pixels where fuzzy reasoning is employed to deal with uncertainties. Results show that proposed method provides better performance in terms of PSNR than many other median filter variants for random-valued impulse noise.
