To be presented at ECCV'26 -- now with user studies (turns out ours is preferred by 90%) and more analysis. We were unsure before how to explain optimizing in Fourier space, but turns out it's plain-old preconditioning.

Initial seed noise matters. And you can optimize it **without** any backprop through your denoiser via good-ol linearization. Importantly, you need to do this in the Fourier space.
