Fuzzy Logic based Adaptive Noise Filter for Real Time Image Processing Applications
Jasdeep Kaur, Preetinder Kaur · International Journal of Computer Applications · 2012
In this paper we implement a new technique for detection and removal of impulse noise from the grayscale digital images.Proposed method consist of the three steps, in the first step, center pixel of the window is tested whether impulse noise is present or not, detected pixel has impulse noise when it lies outside from the trimming range by using fuzzy reasoning.In the second step, we replace the noisy pixels by using median filters.In third stage we create a histogram if the image and again remove the noise by using soft thresholding.The results of the proposed technique for the removal and detection of impulse noise from the gray scale images is very good rather than exiting technique in terms of PSNR values.
