Underwater image enhancement is a technique used to improve the quality of underwater images. Due to the unique properties of the underwater environment, images captured underwater often suffer from degradation caused by absorption and scattering of light. These effects can result in low contrast, blurred images with a dominant blue or green color cast. Enhancement techniques aim to correct these issues and improve the visibility within the image. These methods can include color correction to remove the color cast, contrast enhancement to improve the visibility of underwater objects, and dehazing techniques to reduce the scattering effect. These enhancements are crucial in various applications, including underwater exploration, marine biology research, underwater archaeology, and in improving the performance of underwater vision systems used in autonomous underwater vehicles.

A large scale underwater image (LSUI) dataset is built, which covers more abundant underwater scenes and better visual quality reference images than existing underwater datasets and a novel loss function combining RGB, LAB and LCH color spaces is designed following the human vision principle.
A unified text-to-structure generation framework, namely UIE, which can universally model different IE tasks, adaptively generate targeted structures, and collaboratively learn general IE abilities from different knowledge sources is proposed.
This paper proposes a novel rank learning guided no-reference quality assessment method for UIE, trained based on an elaborately formulated self-supervision mechanism to train a Siamese Network to learn their quality rankings.
This letter proposes a data-driven input reconstruction method from outputs (IRO) based on the Willems’ Fundamental Lemma. Given only output measurements, the unknown inputsestimated recursively by the IRO asymptotically converge to the true input without knowing the initial conditions. A recursive IRO and a moving-horizon IRO are developed based respectively on Lyapunov conditions and Luenberger-observer-type feedback, and their asymptotic convergence properties are studied. An experimental study is presented demonstrating the efficacy of the moving-horizon IRO for estimating the occupancy of a building on the EPFL campus via measured carbon dioxide levels.
This work provides an ingenious manner for the fusion of convolutions and the core attention mechanism to build a Reinforced Swin-Convs Transformer Block (RSCTB) for capturing more local attention, which is reinforced in the channel and the spatial attention of the Swin Transformer.
A novel probabilistic network is presented to learn the enhancement distribution of degraded underwater images that can cope with the bias introduced in the reference map labeling to some extent and capture a robust and stable result.
A ranking-based underwater image quality assessment (UIQA) method, abbreviated as URanker, built on the efficient conv-attentional image Transformer, which can accurately rank the order of underwater images of the same scene enhanced by different underwater image enhancement (UIE) algorithms according to their visual quality.
This work proposes a framework SyreaNet for UIE that integrates both synthetic and real data under the guidance of the revised underwater image formation model and novel domain adaptation (DA) strategies and demonstrates the superiority of this framework over other state-of-the-art learning-based UIE methods qualitatively and quantitatively.
In this work, a novel structure-aware GLM is proposed, fully unleashing the power of syntactic knowledge for UIE, and rich task-adaptive structural bias is learned that greatly resolves the UIE crux, the long-range dependence issue and boundary identifying.
This paper proposes to recast the structured output in the form of code instead of natural language and utilize generative LLMs of code (Code-LLMs) such as Codex to perform IE tasks, in particular, named entity recognition and relation extraction.
