Against the backdrop of the rapid development of computer vision and multimodal AI, image super-resolution reconstruction, as a core research direction in image processing, is widely applied in numerous real-world scenarios such as surveillance and control systems, medical imaging, remote sensing and mapping, and high-definition image restoration. In recent years, multimodal large models have shown excellent abilities in addressing image super-resolution tasks by leveraging text as conditional information, yet their performance on degraded images remains limited. Firstly, this paper reappraises the performance of the Recognize Anything Model (RAM) on degraded images by calculating text similarity, and finds that directly using contrastive learning to fine-tune RAM in degraded space fails to achieve acceptable results. To address this issue, this paper introduces a degradation selection strategy and proposes a Real Embedding Extractor (REE), significantly improving the recognition performance on degraded image content via contrastive learning. Furthermore, via the Conditional Feature Modulator (CFM), the high-level semantic information extracted by REE is integrated into a powerful Mamba-based network. This enables the network to effectively leverage pixel-level information to restore image textures and produce visually pleasing reconstruction results. Extensive experiments demonstrate that the REE can effectively help image super-resolution networks to achieve a balance between fidelity and perceptual quality, while highlightingthe great potential of Mamba in addressing real-world image super-resolution tasks.
