RASR: Retinex-Guided Adaptive One-Step Diffusion for Low-Light Image Super-Resolution
RASR, a Retinex-guided adaptive one-step diffusion framework for low-light super-resolution, outperforms existing low-light and mainstream super-resolution methods in PSNR, SSIM, and LPIPS, with especially prominent gains in perceptual quality, and ablation studies validate the effectiveness of each key design.
