Web1 day ago · Moreover, in text-conditional models, fixing those noise maps while changing the text prompt, modifies semantics while retaining structure. We illustrate how this property enables text-based editing of real images via the diverse DDPM sampling scheme (in contrast to the popular non-diverse DDIM inversion). Webdownstream utilities (e.g. conditional sampling, creative mixing) can be flexi-bly implemented using CHIRODIFF. We further show some unique use-cases like ...
