Abstract
Underwater optical images serve as crucial carriers and representations of ocean information. They play a vital role in the field of marine exploration. However, the quality of images captured by underwater cameras often falls short of the expected standards due to the complex underwater environment. This limitation significantly hampers the application and advancement of intelligent underwater image processing systems. Consequently, underwater image enhancement and restoration have been attracting extensive research efforts. In this paper, we review the degradation mechanisms and imaging models of underwater images, and summarize the challenges associated with underwater image enhancement and restoration. Meanwhile, we provide a comprehensive overview of the research progress in underwater optical image enhancement and restoration, and introduces the publicly available underwater image datasets and commonly-used quality evaluation metrics. Through extensive and systematic experiments, the superiority and limitations of underwater image enhancement and restoration methods are further explored. Finally, this review discusses the existing issues in this field and prospects future research directions. It is hoped that this paper will provide valuable references for future studies and contribute to the advancement of research in this domain.
