Fog and haze are generally a huge cause associated with accidents. Fog reduces the visibility of scene. Fog is formed by the combination of airlight and attenuation. Airlight enhances the whiteness and attenuation reduces the contrast within the scene. Fog detection and removal is a challenging task as it depends upon unknown depth information. Various fog removal methods are used for removing the fog and improving the visibility of scene. This paper gives a review on the various fog removal techniques. These techniques are used in many vision applications. It has been observed that most of the researchers have neglected many issues; i.e. no method is appropriate for different kind of circumstances. The overall objective of this paper is to find the different methods for efficiently eliminating the fog from digital images.
