Minimum Filter
The Minimum Filter is a type of Rank Filter that replaces pixel values with the 0-th percentile ranked, or minimum, value identified in the local neighborhood. Use this filter to remove values above the local statistical "floor". In comparison, the Maximum Filter selects the 100th percentile, or maximum, value in the neighborhood.
This command opens from the Process > Filters menu.
