dc.description.abstract | Underwater images are often acquired in sub-optimal lighting conditions, in particular
at profound depths where the absence of natural light demands the use of artificial lighting.
Low-lighting images impose a challenge for both manual and automated analysis, since regions of
interest can have low visibility. A new framework capable of significantly enhancing these images
is proposed in this article. The framework is based on a novel dehazing mechanism that considers
local contrast information in the input images, and offers a solution to three common disadvantages
of current single image dehazing methods: oversaturation of radiance, lack of scale-invariance and
creation of halos. A novel low-lighting underwater image dataset, OceanDark, is introduced to
assist in the development and evaluation of the proposed framework. Experimental results and a
comparison with other underwater-specific image enhancement methods show that the proposed
framework can be used for significantly improving the visibility in low-lighting underwater images
of different scales, without creating undesired dehazing artifacts. | en_US |
