Abstract: Multi-feature image haze removal is described. In one or more implementations, feature maps are extracted from a hazy image of a scene. The feature maps convey information about visual characteristics of the scene captured in the hazy image. Based on the feature maps, portions of light that are not scattered by the atmosphere and are captured to produce the hazy image are computed. Additionally, airlight of the hazy image is ascertained based on at least one of the feature maps. The calculated airlight represents constant light of the scene. Using the computed portions of light and the ascertained airlight, a dehazed image is generated from the hazy image.

Abstract translation: 描述了多特征图像雾度去除。 在一个或多个实现中，从场景的模糊图像中提取特征图。 特征图传达关于在朦胧图像中捕获的场景的视觉特征的信息。 基于特征图，计算不被大气散射并被捕获以产生模糊图像的部分光。 此外，基于特征图中的至少一个来确定模糊图像的飞行器。 计算出的空气动力表示场景的恒定光。 使用所计算的光部分和所确定的空气光，从模糊图像产生脱色图像。
