A new method for impulsive noise suppression from highly distorted images by using Anfis

A new impulsive noise elimination filter, entitled Anfis-based impulsive noise removing filter (AIF), which shows a high performance at the restoration of images distorted by impulsive noise, is proposed in this paper. AIF uses Anderson-Darling test values in order to determine the pixels which exhibit impulsive behavior within the image. Extensive simulation results show that the proposed filter achieves a superior performance to the other filters mentioned in this paper in the cases of being effective in noise suppression and detail preservation, especially when the noise density is very high.
