Using fuzzy logic to implement a selective median filter to clean noisy images

This paper presents a new fuzzy-logic-control based filter with the properties of removing noise from the noisy images. To reach the above goal, it employs the concepts of fuzzy logic to design a filter to perform the task mentioned above. Before designing the filter program is written by using Visual C++ MFC for loading images and producing test noisy images. This filter is mainly based on the idea that it is not necessary to deal with every pixel using median filter. It uses fuzzy-logic method to "guess" which pixel is noised, then use median filter to change its pixel value. This filter works well for cleaning noisy images.Department of Physics and AstronomyThesis (M.A.
