Public Sub Despeckle() |
Remarks
The most typical use of Despeckle is to eliminate noise or small black areas in an image. These areas are typically caused when the image is printed on a fax machine or as noise when the image is scanned.
Median can also be used to eliminate noise in an image, however, Median is a much harsher filter and has a tendency to distort lettering.
Use this method on images with bit depth greater than one. For bitonal (1-bit) images, use DocumentDespeckle.
Note: Available in Professional Edition.
