It’s amazing that someday we’ll be able to pass in low fidelity pixel art sprite sheets to an AI and get back high definition hand drawn 2D graphics for use in games.

Get out of my head! I literally just registered spritesheet.ai yesterday. and I've already had mild success training a model on spritesheet data.

Someone put out a really compelling one a couple months ago:

I have a question. Stable diffusion is based on gradually processing noise into a coherent image, by training a denoiser. Would it be possible to feed low-fidelity image (such as pixel art, or pixelated image) directly into the denoiser step and get a higher-fidelity image that would match the original?

I think what you are describing is called super-resolution https://ai.googleblog.com/2021/07/high-fidelity-image-genera...

I'm interested in following your project if you have a blog or anything.

I only just recently started building things for fun again (Thanks AI) so I haven't had a blog in many years.

But I'll be launching one on alexbrown.io sometime in the next few weeks to document my projects.

Is there a way to have current AI tools maintain consistency when generating multiple images of a specific creature or object? For example, if there are images of 'Dr. Venom' they need to look similar, or if there are images of the same space ship.

Textual inversion can kind of do this, but I haven't been impressed by examples I've seen. It seems more suited to "Shrek as a lawnmower" than "Shrek reading a book".

midJourney lets you upload a reference image. For a portrait of someone's face this produces consistently the same person.

The title excited me - maybe someone succeeded making new art that looks like the old pre-renders, maybe a convincing imitation of the scanline render look. Instead it was a vapid article about tossing pixel art into img-2-img and getting some tenuously related junk.
