Statistics function

The Statistics function calculates focal statistics for each pixel of an image based on a defined focal neighborhood.

The inputs for this function are the following:

• Input Raster
• Type
• Neighborhood Settings

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:
