DualTSR: Unified Dual-Diffusion Transformer for Scene Text Image Super-Resolution

ArXi:2603.14207v1 Announce Type: cross Scene Text Image Super-Resolution (STISR) aims to re high-resolution details in low-resolution text images, which is crucial for both human readability and machine recognition. Existing methods, however, often depend on external Optical Character Recognition (OCR) models for textual priors or rely on complex multi-component architectures that are difficult to train and reproduce. In this paper, we
