Using threshold switch filter we can remove noise effectively with setting a threshold and dividing the proportion into different segments by this threshold, and then choosing a different filtering algorithm in each segment.Experiment results show that threshold switch filter is the best algorithm camparing to median filter, mean filter and alpha mean filter.This filter can preserve image details and remove most of noise, even in the case of high-density noise and small window.
