Improved Adaptive Median Filter
Zhengyang Guo, Le Zhang · 2014
An improved adaptive median filter is proposed to remove the salt and pepper noise. The algorithm determines a pixel point as signal pixel or possible noise pixel according to the characteristic of the salt and pepper noise, the noise pixel is removed by adaptive median filter, the signal pixel is kept. The results show that the algorithm effectively removes the salt and pepper noise while protecting the edge details of the image.
