In this review paper, we have presented and compared a study of various fog/haze removal algorithms/techniques for image processing. Many algorithms are proposed so far for efficient fog removal. The dark channel prior based fog removal has provided quite promising results over the available techniques. Many researchers have also proposed various improvements in the dark channel prior so far to get better results. The joint trilateral filter based approach has shown more significant results over the available techniques. The overall objective of this review paper is to explore the short comings of the earlier presented techniques used in the revolutionary era of image processing applications.

Keywords: Haze, Dark channel prior, Fog removal, Joint trilateral filter, CLAHE, MIX-CLAHE etc.
