Effective Diffusion Transformer Architecture for High-Quality Image Super-Resolution
The proposed DiT-SR architecture, which combines the advantages of U-shaped and isotropic designs, outperforms existing training-from-scratch diffusion-based super-resolution methods and even rivals the performance of prior-based methods with significantly fewer parameters.
Leveraging Diffusion Prior and Domain Shift for Efficient and High-Performance Image Super-Resolution
A novel diffusion-based super-resolution model, DoSSR, that leverages the generative power of pretrained diffusion models while significantly enhancing inference efficiency through a domain shift strategy and customized stochastic differential equation solvers.
Efficient Conditional Diffusion Model with Probability Flow Sampling for Improving Image Super-Resolution
A conditional diffusion model with probability flow sampling is proposed to efficiently generate high-quality super-resolution images while maintaining consistency with low-resolution inputs.
