Tab Postprocessing (Black & White Mode)
Despeckling
This option removes black pixels in black & white mode, for example from scans of murky originals. The filter searches for
groups of black pixels and converts them into white. Small-sized pixel groups, such as those forming punctuation dots, are
kept.
A L L P I X E L N E I G H B O R S - Pixels are connected neighbors when there is a series of 8 (instead of 4) adjacent pixels, i.e.
additionally to pixels of the same row or column, the diagonally-adjacent pixels are considered to be connected.
F I L T E R S I Z E – It corresponds to the maximum "diameter" of the pixel area which is to be removed.
R E L . A R E A S I Z E – This limits the proportion of the actual maximum number of pixels to the filter size. 0 represents the
smallest possible surface relatively to the selected filter size.
To use this filter:
Select an area with black pixels in the preview.
In the zoom window, open the context menu and select the view 2:1 or 4:1.
In this view, the removed pixels will appear in light gray.
When you make settings with the despeckling filter, be sure not to remove small elements.
