SigmaCommand Constructor(Int32,Int32,Single,Boolean)

Example 





Dimensions of the neighborhood used for filtering.
Number of Standard Deviations of the kernel calculated pixels must be within.
Minimum percentage of pixels included to the number of pixels in the kernel.
Whether the central pixel is included in the calculation of the filter or not.
