I guess you can always use a two-stage process. First colorize, then upscale

- atorodius 3y agoyeah, you can use SOTA super res, but that tends to be generative too (even diffusion based on its own, or more commonly based on GANs). it can be a challenge to synthesize the right high res details. but that’s basically the stable diffusion paper (diffusion in latent space plus GAN superres)
- erwannmillon 3y agoYeah, if you have a high res image, you can get color info at super low-res and then regenerate the colors at high res with another model. (though this isn't an efficient approach at all) https://github.com/TencentARC/T2I-Adapter https://github.com/TencentARC/T2I-Adapter i've also seen a controlnet do this.
