Description
===OverviewThis is a 3x3 (9 sample) "Percentile" filter with an adjustable radius. It provides the functionality of a Median filter (value 5), a Maximum filter (value 9), and a Minimum filter (value 1).For more info see:http://www.filterforge.com/forum/read.php?FID=10&TID=&MID=80553#message80553===Controls:The "Radius" value determines how far apart sample rows and columns are in the 3x3 sample array. Note that increasing the "Radius" value will shift the sample rows and columns farther apart, but will still only sample 9 input pixels for each output pixel. By default, distance is measured as a percentage of the image's total width, where a value of 100 yields a 100% sample separation distance. However, with the "Fine (max = 1%)" option is enabled, a "Radius" value of 100 yields a 1% sample separation distance. It is recommended that you have "Fine (max = 1%)" enabled, and use a small "Radius" value to achieve conventional median / minimum / maximum effects.
