Abstract

In this paper, a fuzzy edge-direction detector is introduced firstly, and then a fuzzy edge-sensitive noise reduction filter is presented in the basis of edge-sensitive noise reduction algorithm proposed by Adelmann (1999). The experimental results show that the method can obtain better results than Adelmann's and other schemes, such as Russo's FIRE filter (1997), in respect of smoothing impulse, Gaussian and mixed noise and preserving edges.
