How to use the pammixinterlace command: Merge each row in an image with its two neighbours. See also: pamdeinterlace. More information: <https://netpbm.sourceforge.net/doc/pammixinterlace.html>.

Solution

pammixinterlace — Merge each row in an image with its two neighbours. See also: pamdeinterlace. More information: <https://netpbm.sourceforge.net/doc/pammixinterlace.html>.

Merge each row in an image with its two neighbours:

pammixinterlace {{path/to/image.ppm}} > {{path/to/output.ppm}}

Use the specified filtering mechanism:

pammixinterlace {{[-f|-filter]}} {{linear|fir|ffmpeg}} {{path/to/image.ppm}} > {{path/to/output.ppm}}

Turn on adaptive filtering mode, i.e., only modify pixels that are obviously part of a comb pattern:

pammixinterlace {{[-a|-adaptive]}} {{path/to/image.ppm}} > {{path/to/output.ppm}}
