Made a little thing to take fast approximate multivariate medians, at no small cost to my sanity, and it turns out that when I apply it to pixels in California Landscapes time lapse videos (e.g., onewilshire.la/@CALandscapeBot) it’s mostly just Compression Artifact Finder 2023 Pro Edition.

A wonderful thing about image processing is you’re always discovering completely new and fascinating ways to make pictures look worse.

@vruba yeah after our previous conversation about this a few months ago, I tried a bunch of things and it only got worse too. the Axis cameras are aggressively compressing but also doing a very destructive unsharp mask/sharpening thing first. hopeless.

@midendian Yeah, this example is cherry-picked for minimal camera shake, and I downsampled before doing anything, and I’m pretty sure you can still find shake-induced artifacts if you look.
