<h1>Median Filter</h1>
This filter is based on [ConvolutionMatrix|Convolution Matrix] filter but instead of calculate central point in filter window (in aperture) with special formula, it's sort all points and use central point of sorted points and central point of window. So, if there is big impulse in window's central point then it will be replaced by "median" point. It's good to filter "salt and piper" noise.
