Abstract
In this paper, four fuzzy filters for filtering images contaminated with random, impulse, and sum of random and impulse noises are introduced. In each of these four fuzzy filters, the output pixel of a filtered image at the center of a moving window area is defined as a normalized sum of weighted input pixels within the window. Simulation results indicate that some of these fuzzy filters show improvement over the standard median and moving average filters in reducing these three noises.
