Nonlinear Edge Preserving Filtering Techniques for Image Enhancement.

Abstract

Recently introduced generalizations of the median filter (namely the alpha-trimmed mean and modified trimmed mean filters) are reviewed and related to a class of nonlinear filters called selective averaging filters, and two new filters are defined. These filters are examined for performance on noise-corrupted images and shown to have good smoothing characteristics without edge smearing.
