Coupled Continuous-Discrete Generation for Scene Text Image Super-Resolution

DualTSR is presented, a unified framework that formulates STISR as coupled continuous-discrete generation and achieves the best FID, LPIPS, ACC, and NED among the compared methods at both X2 and X4.

MeanSR: Restoration Trajectory Learning for One-Step Perceptual Super-Resolution

This work proposes MeanSR, a one-step perceptual SR method that learns an LR-conditioned average velocity field to directly capture the finite-time transition from degraded or noisy inputs to plausible HR outputs and introduces a Stage-Aware Temporal Sampling strategy to improve trajectory learning.
