Image dehazing is an ill-posed problem that has been extensively studied in the recent
years. The objective performance evaluation of the dehazing methods is one of the major …

Haze removal or dehazing is a challenging ill-posed problem that has drawn a significant
attention in the last few years. Despite this growing interest, the scientific community is still …

Images degraded by light scattering and absorption, such as hazy, sandstorm, and
underwater images, often suffer color distortion and low contrast because of light traveling …

Image dehazing has become an important computational imaging topic in the recent years.
However, due to the lack of ground truth images, the comparison of dehazing methods is not …
