A Survey on the Enhancement of Hazy Images

2017 International Journal of Recent Trends in Engineering and Research  
Due to the adverse weather conditions like the presence fog or heavy rain, digital images are easily subjected to a wide variety of disturbance during acquisition, which may reduce visual effect and affect post-processing of the image. Images degraded by fog adversely affect the quality of vision-based physical security system. This leads to accidents in air, on sea and on the road. However, for improving the image appearance to a human viewer, or to convert an image to a format better suited

For improving the visibility level 4 major steps are used. These steps are image acquisition, image estimation, image enhancement and image restoration. The main goal of the paper is given an overall existing review for the foggy image enhancement techniques with some future references.
