Direct Conditional Transition Sampling for Diffusion Inverse Problems
Qi Yu, Hanlin Wu, Xiaohui Sun
Training-free diffusion inverse solvers typically choose between local measurement guidance and costly clean-space posterior updates. Independent posterior refresh can improve glob…
Linearized Coupling Flow with Shortcut Constraints for One-Step Face Restoration
Xiaohui Sun, Hanlin Wu
Face restoration can be formulated as a continuous-time transformation between image distributions via Flow Matching (FM). However, standard FM typically employs independent coupli…
Single-Step Latent Consistency Model for Remote Sensing Image Super-Resolution
Xiaohui Sun, Jiangwei Mo, Hanlin Wu +1
Recent advancements in diffusion models (DMs) have greatly advanced remote sensing image super-resolution (RSISR). However, their iterative sampling processes often result in slow…
Latent Diffusion, Implicit Amplification: Efficient Continuous-Scale Super-Resolution for Remote Sensing Images
Hanlin Wu, Jiangwei Mo, Xiaohui Sun +1
Recent advancements in diffusion models have significantly improved performance in super-resolution (SR) tasks. However, previous research often overlooks the fundamental differenc…
