WebThe proposed method estimates the haze thickness map, which represents the amount of the haze. The haze removal is performed using the atmospheric scattering model. Experimental results demonstrate that the proposed method can perform haze removal without over-dehazing and color distortion compared with existing methods. WebJun 1, 2024 · Makarau et al. (2014) calculated a haze thickness map via dark-object subtraction to dehaze both calibrated and uncalibrated multispectral images. The correlation between the visible (or infrared) band and the cirrus band was also utilized for haze removal in Xu et al. (2014).

WebThe weight maps of both base and detail layers are constructed for image fusion. So, the fog-free image is obtained after fusing the base and detail layers. This paper has two main contributions as follows. 1. The proposed method can effectively avoid the complex process of both scene depth a priori estimation and depth mapping. When light strikes the surface of a transparent material the following interactions occur – • Light is reflected from the front surface of the material • Some light is refracted within the material (depending on thickness) and reflected from the second surface
