The paper titled "Taming Diffusion Prior for Image Super-Resolution with Domain Shift SDEs" presents a novel approach to image super-resolution (SR) using diffusion-based models. Authored by Qinpeng Cui and a team of eight other researchers, the work addresses the challenges faced by existing diffusion models, particularly in balancing efficiency and performance. Diffusion-based SR models have gained popularity due to their strong capabilities in image restoration. However, many of these models either fail to leverage the full potential of pre-trained models, which limits their generative abilities, or they require numerous forward passes starting from random noise, leading to inefficiencies during inference. The authors introduce a new model called DoSSR, which stands for Domain Shift diffusion-based SR. This model enhances efficiency by initiating the diffusion process with low-resolution images, thereby capitalizing on the generative strengths of pre-trained diffusion models. Central to the proposed method is a domain shift equation that integrates smoothly with existing diffusion models. This integration not only optimizes the use of diffusion prior but also significantly improves inference efficiency. The authors further advance their approach by transitioning from a discrete shift process to a continuous formulation, referred to as DoS-SDEs. This transition enables the development of fast and customized solvers that enhance sampling efficiency. Empirical results indicate that the DoSSR model achieves state-of-the-art performance on both synthetic and real-world datasets, requiring only five sampling steps. This represents a substantial improvement in speed, achieving a remarkable speedup of 5-7 times compared to previous diffusion prior-based methods.
