Timestep-Aware Diffusion Model for Extreme Image Rescaling

ICCV 2025poster

Image rescaling aims to learn the optimal low-resolution (LR) image that can be accurately reconstructed to its original high-resolution (HR) counterpart, providing an efficient image processing and storage method for ultra-high definition media. However, extreme downscaling factors pose significant…
