I just came across this question I asked 13 years ago about pixelating images using the command line

graphicdesign.stackexchange.co

That method of downscaling then upscaling to produce pixelation was acceptable at the time but the problem is that you couldn't easily specify the size of the "big pixels"

Searching again in 2025 and it looks like ffmpeg has had a pixelation filter since 2022 and can be used like this:

ffmpeg -i input.mp4 -vf pixelize=40:40 output.mp4

So now I'm using ffmpeg, a video editor, to pixelate images.

Le résultat donne des info plus faciles à lire que sur l'image IR seule.
Normalement, si on n'a pas un mégalabo, on fait ça à la main, sur Photoshop, un programme géant.

J'ai réussi à créer une ligne de #imagemagick qui fait la même opération sans devoir acheter, lancer, ouvrir, manipuler un produit Adobe.

Le résultat de la manipulation fausse couleur est visible ci-dessous. Beaucoup plus intuitif et facile à analyser que l'image RVB ou IR seules.
