A pbm image filter for scanned multipage documents
Published on 2020-01-22
I always scan important and unimportant letters into digital documents, whereas the physical papers are archived only for a few months and then going to be dropped. Digital documents can surely better be sorted, categorized and they are digitally searchable. Besides, the next time when I have to move to another apartment, there is no need to carry all papers. However, the scanned documents sometimes have artifacts like false alarms in the empty spaces and white spots within black strokes. In order to fix that, I wrote a image filter to handle them in a quick and dirty way.
