WebAug 18, 2024 · Median filter is a highly highly nonlinear filter (it re-orders the sample positions!). The output of the median filter at a position n is the median of the values that reside in the window scope; i.e., it's the value that resides in the middle when the samples are sorted in order. Hence median filtering requires sorting for each computation. WebAug 10, 2024 · The median filter calculates the median of the pixel intensities that surround the center pixel in a n x n kernel. The median then replaces the pixel intensity of the center pixel. The median filter does a better job of removing salt and pepper noise than the mean and Gaussian filters. character stereotypesWebMost of the answers here seem to center on performance optimizations of the naive median filtering algorithm.
