USAGE

.OPERATION: DU

.INPUT FILE: PIC001
[Enter the name of the image that is to be "dusted". Note: The file will be overwritten by the new data!]

[The original standard deviation and density range of the picture are printed on the terminal.]

.STANDARD DEVIATION FACTOR: 3
[This factor defines the bottom and top sided truncation of the data. In the given case, all data that are smaller than (MODE-3 * S.D.) and all data larger than (MODE+3 * S.D) are replaced by the threshold values.]

.(1) BOTTOM (2) TOP (3) BOTH SIDES: 3
[Specify if you want one-sided or two-sided truncation. The pixels with density higher than the ceiling will
