Recently, improving the visual quality of an underwater image by deep learning-based methods has drawn much attention. Unfortunately, in real-world environments, diverse environmental factors (e.g., blue/green color distortion) heavily limit their performance. In other words, strengthening the robustness of the underwater image enhancement method is the critical point.
In this paper, we devote ourselves to develop a new architecture with strong robustness and adaptation. Concretely, inspired by the underwater imaging principle, we establish a new physics-inspired learning model that easy to realize. A Structure-Aware Texture-Sensitive Network (SATS-Net) is further developed to portray the model. In which, the structure-aware module is responsible for structural information, and the texture-sensitive module is in charge of textural information. In this way, SATS-Net successfully incorporates robust characterization absorbed from the physical principle to achieve strong robustness and adaptation. We conduct extensive experiments to verify that SATS-Net is superior to existing advanced techniques in various real-world underwater environments.
