Abstract

The work in this paper presents a technique to improve the contrast of weather degraded images due to fog/haze. The proposed technique exploits guided filter to deal with the problems of color saturation and detail contrast enhancement, while maintaining the structural similarity to the input image. Experimental comparisons with state-of-the-art algorithms demonstrate that proposed approach can retrieve the contrast in detail without generating halos and avoids oversaturation in colors. Quantitative analysis also reveals the superiority of the proposed algorithm over existing schemes.
