Researchers have developed new methods to evaluate and improve text-aware image super-resolution (TAISR) models, which aim to restore high-resolution images while preserving text. Existing TAISR models struggle with severely degraded text that requires reasoning beyond visual cues. To address this, a new benchmark called ReasonText was created to identify text that necessitates reasoning, alongside a metric called Ground-Truth Text-Crop Accuracy (GTTCA) to measure text restoration quality accurately. Experiments showed a significant performance drop in current TAISR models on reasoning-required text, highlighting a gap in their capabilities. The study also found that multimodal large language models (MLLMs) can effectively read degraded text through reasoning, leading to the development of Reasoning Transfer via Captioning (RTC). This plug-in uses an MLLM to infer text and feed it to a text-conditioned SR model, consistently improving performance, particularly on challenging reasoning-based text restoration tasks. AI
