Garrett Gunnell explains the history, math, and implementation of the Kuwahara filter for artistic post-processing and denoising.

30 years ago a man attempted to denoise medical imagery and unknowingly set off a chain reaction of research developments leading to a modern day post processing effect that transforms images into paintings, but how did he do it?

What people say. Highly recommended as an excellent resource for understanding and implementing the Kuwahara filter in shaders.

On “How could this effect be replicated in a shader?”

If you're looking to replicate it as a still, on top of dithering, one thing I'd suggest is to implement something like PCF shadows and SSAO, but only use a single texture sample. I think that could help to get the stippled shadow effects. Though it wouldn't really work in motion. You should also look into the Kuwahara filter. This video is a _great_ resource for that. That being said, I think a lot of the style would come from the assets you feed into it rather than the shading.
