Query: An Underwater Image Enhancement Benchmark Dataset and Beyond   Underwater image enhancement has been attracting much attention due to its
significance in marine engineering and aquatic robotics. Numerous underwater
image enhancement algorithms have been proposed in the last few years. However,
these algorithms are mainly evaluated using either synthetic datasets or few
selected real-world images. It is thus unclear how these algorithms would
perform on images acquired in the wild and how we could gauge the progress in
the field. To bridge this gap, we present the first comprehensive perceptual
study and analysis of underwater image enhancement using large-scale real-world
images. In this paper, we construct an Underwater Image Enhancement Benchmark
(UIEB) including 950 real-world underwater images, 890 of which have the
corresponding reference images. We treat the rest 60 underwater images which
cannot obtain satisfactory reference images as challenging data. Using this
dataset, we conduct a comprehensive study of the state-of-the-art underwater
image enhancement algorithms qualitatively and quantitatively. In addition, we
propose an underwater image enhancement network (called Water-Net) trained on
this benchmark as a baseline, which indicates the generalization of the
proposed UIEB for training Convolutional Neural Networks (CNNs). The benchmark
evaluations and the proposed Water-Net demonstrate the performance and
limitations of state-of-the-art algorithms, which shed light on future research
in underwater image enhancement. The dataset and code are available at
