A New Filter Algorithm of Image Based on Fuzzy Logical

Abstract

Image denoising by using the filter algorithm is a basic problem which we would meet during the image processing. The mean filter is normally used to reduce Gaussian noise, but it is not effective to the impulse noise. While the median filter is good for reducing the impulse noise but is not well-worked for Gaussian noise. Based on the idea of fuzzy logical, this essay proposes a new kind of filter, the fuzzy filter, which could deal with the two types of noise above to some extent. Finally, according to the experiment data, we have evaluated the performance of the fuzzy filter comparing with the traditional filters and the result is acceptable.
