Median Filter
The Median Filter applies a rank filter which selects the 50th percentile ranked pixel from within the local neighborhood. This filter is used to remove high-frequency information and noise from an image, a process known as "smoothing". The median filter does not calculate a replacement value by combining neighborhood values but, rather, selects one of the neighborhood values to use as the replacement.
This command opens from the Process > Filters menu.
