"""
This plugin open a new stack window with a configurable median filter
applied to the data.
The user can select the frame and modify the filter width.
He can also choose to apply a conditional median filter instead
of the regular median filter.
With a regular median filter, each pixel value is replaced with the median
value of all pixels in the window. With the conditional option enabled,
the pixel value is only replaced if it is the minimum or the maximum value
in the smoothing window.
