New Image Quality Evaluation Metric for Underwater Video
IEEE Signal Processing Letters, 2014This work presents a new vectorial underwater image quality metric, dubbed the CQ, that integrates the power spectrum. Unlike existing objective underwater image quality metrics, the proposed metric consists of a discriminator $C$ based on the slope of the log-contrast power spectrum that is able to distinguish between marine habitats when a large

An Online Platform for Underwater Image Quality Evaluation
2018With the miniaturisation of underwater cameras, the volume of available underwater images has been considerably increasing. However, underwater images are degraded by the absorption and scattering of light in water. Image processing methods exist that aim to compensate for these degradations, but there are no standard quality evaluation measures or ...

Underwater Image Restoration by Turbulence Model based on Image Quality Evaluation
International Journal of Advancements in Computing Technology, 2012For the underwater degenerative image caused by obscure and noise, atmospheric turbulence model is utilized to construct the restoration model. By computing the underwater image quality function which is used to estimate the adaptive degradation model parameter, underwater image is restored through Wiener filters.

Subjective and objective quality evaluation of sonar images for underwater acoustic transmission
2017 IEEE International Conference on Image Processing (ICIP), 2017One of the most critical missions of sonar is to capture deep-sea pictures to depict sea floor and various objects, and provide an immense understanding of biology and geology in deep sea. Due to the poor condition of underwater acoustic channel, the captured sonar images very possibly suffer from several typical types of distortions before finally ...

New non-reference image quality evaluation method for underwater turbulence blurred images
Proceedings of the Thirteenth ACM International Conference on Underwater Networks & Systems, 2018Turbulence is an important cause of image distortion in an underwater ocean environment, along with light scattering and color reduction. Turbulence blur is a universal phenomenon of underwater image degradation, and causes a loss of high frequency portion and image detail.

Performance evaluation of underwater range-gated viewing based on image quality metric
2009 9th International Conference on Electronic Measurement & Instruments, 2009A underwater imaging prototype system is built based on range gate mechanism. The no-reference image quality metric which is the sum of weight information capacity based on co-occurrence matrix of different direction is proposed in this paper in order to study the system performance according to different parameters. The tank trail is processed. In the

UQ-Bench: A Benchmark for Evaluating Multimodal LLMs on Underwater Image Quality Assessment
Proceedings of the AAAI Conference on Artificial IntelligenceDespite the rapid progress of multimodal large language models (MLLMs), their capacity for low-level visual perception in underwater environments remains underexplored. To address this gap, we present UQ-Bench, the first systematically designed benchmark for evaluating the ability of MLLMs to perceive and assess underwater image quality at the low ...
