SlimDiffSR: Toward Lightweight and Efficient Remote Sensing Image Super-Resolution via Diffusion Model Distillation
Ce Wang, Zhenyu Hu, Wanjie Sun
Diffusion models have recently achieved remarkable performance in image super-resolution (SR), but their high computational cost limits practical deployment in remote sensing appli…
InstaVSR: Taming Diffusion for Efficient and Temporally Consistent Video Super-Resolution
Jintong Hu, Bin Chen, Zhenyu Hu +3
Video super-resolution (VSR) seeks to reconstruct high-resolution frames from low-resolution inputs. While diffusion-based methods have substantially improved perceptual quality, e…
Unifying Dimensions: A Linear Adaptive Approach to Lightweight Image Super-Resolution
Zhenyu Hu, Wanjie Sun
Window-based transformers have demonstrated outstanding performance in super-resolution tasks due to their adaptive modeling capabilities through local self-attention (SA). However…
Timestep-Aware Diffusion Model for Extreme Image Rescaling
Ce Wang, Zhenyu Hu, Wanjie Sun +1
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 im…
