Abstract

The quality of an image in any image processing algorithm plays a vital role as the quality of image is a primary thing. There are several techniques employed to enhance the quality of the image. Few techniques are applied to all images irrespective of the noise and few are employed to reduce particular type of noise present in the images. In this paper a new method is used for the noise reduction of images contaminated with Gaussian noise by using fuzzy image filter wherein the fuzzy derivatives are derived with the help of fuzzy rules which are then used for the fuzzy image smoothing technique to reduce the noise that also uses the values of membership functions. Here the technique of smoothing is applied to de-noise the image, later the de-fuzzification techniques are applied to get the de-noised image. The result shows the most efficient filter to remove the white Gaussian noise. Marking the maximum and minimum performance of filter for different images helps in designing and comparing the new filters which give better results than the existing filters.
