Impulse Noise Filtering Using Robust Pixel-Wise S-Estimate of Variance

A novel method for impulse noise suppression in images, based on the pixel-wise S-estimator, is introduced. The S-estimator is an alternative for the well-known robust estimate of variance MAD, which does not require a location estimate and hence is more appropriate for asymmetric distributions, fre...
