An Improved Adaptive Median Filter for Image Denoising
Chunmei Wang, Tianyi Li · 2012
In this paper, we proposed a new adaptive median filter for image denoising. In our method, two thresholds have been involved for detecting noises in variable-sized windows. The median filter and the mean filter are combined for changing the value of the corrupted pixels. The filter can preserve the fine details of image while suppressing the impulsive-type noise. The results of the experiments proved that our method is better than the traditional median filters. Keywords-salt & pepper noise, adaptive median filter, standard median filter, extreme median filter
