Abstract: The median filter is a kind of effective noise suppression technique, especially in salt &pepper noise removal widely application. This paper aim at improving traditional median filtering the shortcomings of the methods, with double threshold detection noise, and in medical image experiment, the result shows that the improved median filter method than traditional median filter to achieve better denoising effect, image is more clear.
