Basically, I’d like to delete tattoos or somehow blend the area to match the uninked skin nearby, and also to cartoonify (preferrd) or blur faces. If there’s a free/simple app where I could just select and click a button that would be great, but if not if someone could tell me or link me to a guide on how to do that I’d appreciate it.
Side note… almost any app is going to sacrifice the privacy of your original image to The Cloud. If you don’t mind that and you legit sub to CC Photoshop, you can get the Ps betas and use their Firefly generative engine for AI infilling.
Staying with foss, there is a GIMP plugin for Stable Diffusion on StableHorde (a crowdsourced distributed network).
