Researchers have developed PRISM, a novel diffusion-based framework for text image super-resolution that enhances readability under severe degradation. The system employs Flow-Matching Prior Rectification (FMPR) to create a more accurate global text guidance from unreliable low-quality inputs. Additionally, a Structure-guided Uncertainty-aware Residual Encoder (SURE) refines local stroke boundaries by selectively incorporating reliable cues and suppressing ambiguous ones. PRISM achieves state-of-the-art performance with rapid inference times. AI
