Profile Picture

I made a couple profile pictures with the same process, and I want to document it here and maybe automate it.

The intended goal is for an image to be recognizable, but also abstract enough. In my case I do it by clustering the pixels of similar colors together and then swapping the palette. I really like the "Posterize" effect many applications have, but it's limited to specific colors. What I do instead of the same, but with any colors I want, and using threshold which better fit the image.

I tried to recreate it and realize I've forgotten how. I'll look it up and finish this article.
