The Median Filter block computes the moving median of the input signal along each channel independently over time. The block uses the sliding window method to compute the moving median. In this method, a window of specified length moves over each channel sample by sample, and the block computes the median of the data in the window.

Image Processing using Matlab Max and min filtering are frequent operations that we perform during image processing. Although the code apply max and min filtering is very simple and straightforward, because of lack of programming practice, sometimes we face difficulties to write program to apply max and min filter on image using MATLAB.

y … A median filter in images works the same way, only in 2D. So you take not only the values (pixels) that are left or right, but all the values that surround the sample (pixel) … Median filtering is particularly useful for salt-and-pepper noise where it is highly probable that these noisy pixels will appear the beginning and at the end when sorting pixel neighbourhoods, so choosing the middle value will most likely filter out these noisy values.
