Abstract:Imaging in the atmosphere presents the phenomenon of low contrast, low saturation and hue offset due to atmospheric particles such as haze and fog.In this paper, a fast method is proposed to remove haze from a single image based on modified bilateral filtering.The similar Gaussian kernel that is firstly proposed in this paper is applied to structure the modified bilateral filtering.The modified bilateral filtering is a linear edge preserving filter and is used to refine medium transmission;meanwhile, it can effectively enhance the speed of data processing.The dark channel prior and fog image are used to accurately estimate the value of global atmospheric light by an interval through weighted fusion.Compared to some state-of-the-art methods, the proposed method can achieve a faster processing speed, effectively improve the visibility and contrast of the restored images, and obtain good color effect.
