Poisson flow consistency models for low-dose CT image denoising

no code implementations13 Feb 2024 Dennis Hein, Adam Wang, Ge Wang

In this paper, we introduce a novel image denoising technique which combines the flexibility afforded in Poisson flow generative models (PFGM)++ with the, high quality, single step sampling of consistency models.
