Median filter. The median filter is also a sliding-window spatial filter, but it replaces the center value in the window with the median of all the pixel values in the window. As for the mean filter, the kernel is usually square but can be any shape.

The MF most appealing feature is its resistance to noise and errors in data, but Like most things in embedded systems, median filters have certain costs associated with them. Clearly median filters introduce a delay to a step change in value which can be problematic at times. In addition median filters can completely clobber frequency information in the signal. 2016-02-11 · The median filter, when applied to grayscale images, is a neighborhood brightness-ranking algorithm that works by first placing the brightness values of the pixels from each neighborhood in ascending order. The median or middle value of this ordered sequence is then selected as the representative brightness value for that neighborhood.
