WebAug 24, 2024 · The median filter works by moving through the image pixel by pixel, replacing each value with the median value of neighbouring pixels. The pattern of neighbours is called the “window”, which slides, pixel by pixel, over the entire image. WebNote: The MEDIAN function measures central tendency, which is the location of the center of a group of numbers in a statistical distribution. The three most common measures of central tendency are: Average which is the arithmetic mean, and is calculated by adding a group of numbers and then dividing by the count of those numbers.
