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?
- mschulkind 4y agoYes, stable diffusion has an img2img mode that does essentially exactly that.
- sigmar 4y agoI think what you are describing is called super-resolution https://ai.googleblog.com/2021/07/high-fidelity-image-generation-using.html https://ai.googleblog.com/2021/07/high-fidelity-image-genera...
- charcircuit 4y agoIt's noise in a latest space which is different from noise in the image that the vector represents.
