MedianFilter

MedianFilter[image, r]
filters image by replacing every value by the median in its range r neighborhood.

MedianFilter[data, r]
applies median filtering to an array of data.

MedianFilter[image, r] finds the median in (2r+1)×(2r+1) blocks centered on each pixel.

MedianFilter[image, {r₁, r₂}] uses neighborhoods with vertical range r₁ and horizontal range r₂.

For multichannel images, MedianFilter[image, ...] replaces each pixel by a pixel in its neighborhood that has the median total intensity, averaged over all channels.
