| Description: |
Filter to compute the Extremum Filtered Image. This computes the maximum, minimum and average images within a 3x3 neighbourhood.Whichever of the minimum or maximum is closest to the mean is substituted for the pixel value. This filter posterises an image, reducing the number of grey levels, filtering out noise and making edges more abrupt. |

There is a limitation (or conflict) in User Defined Language with DM script. The operation "/" and "*" cannot be defined as operators in Notepad++ once we define "/*" and "*/" as comment block markers. So I have left "/" and "*" out from the operator list |
