There are four types of focal statistical functions:
 Minimum—Calculates the minimum value of the pixels within the neighborhood
 Maximum—Calculates the maximum value of the pixels within the neighborhood
 Mean—Calculates the average value of the pixels within the neighborhood
 Standard Deviation—Calculates the standard deviation value of the pixels within the neighborhood
The Neighborhood Settings allow you to enter the number of pixel rows and columns to use as your neighborhood dimensions.
The table below provides examples of the types using two different neighborhood dimensions based on the following image:
