U-Shape Transformer for Underwater Image Enhancement

🤖 Plain-English Summary

The light absorption and scattering of underwater impurities lead to poor underwater imaging quality. The extensive experiments on available datasets validate the advanced performance of the reported technique with more than 2dB superiority.

🔑 Key Findings

• The existing data-driven based underwater image enhancement (UIE) techniques suffer from the lack of a large-scale dataset containing various underwater scenes and high-fidelity reference images.
• Besides, the inconsistent attenuation in different color channels and space areas is not fully considered for boosted enhancement.
• In this work, we built a large scale underwater image (LSUI) dataset, which covers more abundant underwater scenes and better visual quality reference images than existing underwater datasets.
