PixSDS: Why Latent SDS Makes Noisy Pixels
PixSDS is proposed, a lightweight VAE-consistent gradient repair method that decodes a latent SDS lookahead step and uses the decoded image as a clean direction for pixel-space optimization, reducing motion in VAE-inconsistent directions without retraining the diffusion model, changing the renderer, or replacing the SDS objective.
