An Impulse Noise Image Filter Using Fuzzy Sets

The successful application of fuzzy set theory operators on several domains, along with the increasing need for processing digital images, have been the main motives behind the efforts concentrated on fuzzy sets. Fuzzy set theory, comparing with some other theories, can provide us with knowledge-based and robust tools for image processing. By computing the fuzziness of the pixelspsila corrupted degree and taking corresponding filter parameters, a new image filter for impulse noise is presented in this paper. Comparing with the median filter, which is excellent for impulse noise, this new filter is more effective. In the end,simulation results show that the new algorithm is feasible.
