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.
The Median Filter command opens from the
Image Window > Process >
Filters menu and 
button
on the Main Toolbar. The "immediate"
form, shown first, opens when an image or image set is displayed in
the top-most window. The general form can be used to select source
images from folders, windows, or by matching templates.
