This allows our method togenerate sharp edges more easily than an individual network.

Structured prediction is the task of predicting an output which itself contains internal structure. As an example, consider the problem of image segmentation.

In this paper, we present DoSSR, a Do main S hift diffusion-based SR model that capitalizes on the generative powers of pretrained diffusion models while significantly enhancing efficiency by initiating the diffusion process with low-resolution (LR) images. At the core of our approach is a domain shift equation that integrates seamlessly with existing diffusion models. This integration not only improves the use of diffusion prior but also boosts inference efficiency. Moreover, we advance our method by transitioning the discrete shift process to a continuous formulation, termed as DoS-SDEs. This advancement leads to the fast and customized solvers that further enhance sampling efficiency.
