Maximum Filter
The Maximum Filter is a type of Rank Filter that replaces pixel values with the 100th percentile ranked, or maximum, value identified in the local neighborhood. Use this filter to remove values below the local statistical "ceiling". In comparison, the Minimum Filter selects the 0-th percentile, or minimum, value in the neighborhood.
The Maximum 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.
