pbmclean

Clean up a PBM image by erasing isolated black and white pixels. More information: https://netpbm.sourceforge.net/doc/pbmclean.html.

• Clean up a PBM image by erasing isolated black and white pixels:

pbmclean {{path/to/image.pbm}} > {{path/to/output.pbm}}

• Clean up only black/white pixels:

pbmclean -{{black|white}} {{path/to/image.pbm}} > {{path/to/output.pbm}}

• Specify the minimum number of neighbouring pixels of the same color in order for a pixel not to be considered isolated:

pbmclean {{[-m|-minneighbours]}} {{3}} {{path/to/image.pbm}} > {{path/to/output.pbm}}
