Evaluation of Various Digital Image Fog Removal Algorithms

Abstract: This paper is a review on the various fog removal algorithms. Fog removal otherwise called visibility restoration refers to diverse systems that suppose to lessen or evacuate the degradation that have happened while the digital picture was being acquired. In this paper, various fog removal techniques have been analysed. It has been shown that each fog removal technique has its own features and drawbacks. The presented methods have neglected the techniques to reduce the noise issue, which is presented in the output images of the existing fog removal algorithms. Not much effort has focused on the integrated approach of the CLAHE and Dark channel prior. The problem of the uneven illuminate has also neglected by the most of the researchers.

Keywords: Fog removal, image enhancement, visibility restoration.
