Abstract:
Fog removal also known as visibility restoration refers to different methods that aim to reduce or remove the degradation that have occurred while the digital image was being obtained. The degradation may be due to various factors like relative object camera motion, blur due to camera missfocus, relative atmospheric turbulence and others. This paper has focused on the various fog removal techniques. Haze removal has found to be tough task because fog depends on the unknown scene depth information. Fog effect is the function of distance between camera and object. Therefore, the removal of fog requires the estimation of air light map. The current haze removal technique can be categorized as: image enhancement and image restoration however, the image enhancement does not incorporate the reasons of fog corrupting the image quality. The proposed VR technique consists of 3 modules DE module, CA module and VR approach.
