Nighttime Hazy Cityscapes (NHC)
收藏资源简介:
Nighttime Hazy Cityscapes (NHC) 数据集由悉尼大学人工智能中心创建,旨在为夜间雾霾图像的去雾研究提供基准。该数据集包含2750张通过合成方法生成的夜间雾霾图像,这些图像源自Cityscapes数据集的清晰日间图像。数据集的创建过程涉及场景几何重建、光线和物体反射模拟以及雾霾效果渲染。NHC数据集主要用于评估和改进夜间雾霾图像的可见度,解决由于不均匀光照和雾霾吸收/散射导致的视觉挑战。
The Nighttime Hazy Cityscapes (NHC) dataset was developed by the Centre for Artificial Intelligence at the University of Sydney, aiming to provide a benchmark for dehazing research on nighttime hazy images. It contains 2750 synthetic nighttime hazy images derived from the clear daytime images of the Cityscapes dataset. The dataset creation process involves scene geometry reconstruction, simulation of lighting and object reflections, and haze effect rendering. The NHC dataset is primarily used to evaluate and enhance the visibility of nighttime hazy images, addressing visual challenges caused by uneven lighting and haze absorption and scattering.
