We show that seemingly different direct diffusion bridges are equivalent, and that we can push the pareto frontier of the perception-distortion tradeoff with data consistency gradient guidance.
TPDM improves 3D voxel generative modeling with 2D diffusion models. We show that 3D generative prior can be accurately represented as the product of two independent 2D diffusion priors that scale to both unconditional sampling and solving inverse problems.
We propose a method that can solve 3D inverse problems in the medical imaging domain using only the pre-trained 2D diffusion model augmented with the conventional model-based prior.
Diffusion posterior sampling enables solving arbitrary noisy (e.g. Gaussian, Poisson) inverse problems that are both linear or non-linear.
Manifold constraint dramatically improves the performance of unsupervised inverse problem solving using diffusion models.
