FILTERING OF MAGNETIC RESONANCE IMAGES USING AN ADAPTIVE HYBRIDIZED FUZZY FILTER

- An image should be processed carefully in order to get its optimized form. The main problem during the acquisition of the images through electronic ways and means is the noise that arises. The denoising capability of the median filter is better compared to most of the available filters and hence we look into it. The elevated version of median is the adaptive median filtering which includes spatial information for the conservation of every detail and also the reduction of noise. In case of uncertainty, Fuzzy logic works well. Here, we filter the impulsive salt and pepper noise in MRI images. A median filter that uses Fuzzy logic and the adaptive median filter are compared with the modified Type 2 Fuzzy filter that is suggested for the denoising approach. Their outputs are compared to show its outperformance by using the PSNR, and Structural Similarity index parameters.
