Shuwei Huang, Tianyao Luo, Jicheng Liu, Daizong Liu, Pan Zhou
Image super-resolution (ISR) has witnessed remarkable progress with diffusion models and flow matching. The dominant text-to-image (T2I) based approaches leverage large-scale foundation models as generative priors, achieving impressive perceptual quality but at the cost of massiv…
