Fog is a big reason for road accidents. Images which are captured under bad weather conditions suffer low contrast so as their quality also degrade with the changes in atmosphere. The main reason behind this problem is that, the light capture by the lens is spread by the atmosphere. Fog reduces visibility to less than 1 kilometre. This paper aims to resolve the sight problem faced by car/other automobile drivers when driving in foggy weather condition and at night. For improving the visibility level of an image and reducing fog, various image enhancement methods are used. For improving the visibility level five major steps are used. First step is acquisition process of foggy / dark images. Second is estimation process. Third is enhancement process (improve visibility level, reduce fog). Next process is restoration process (restore enhanced image) while the final is the vehicle detection. The main aim of the paper is to review image enhancement and restoration methods for improving the quality and visibility level of an image which provide clear image in bad weather condition.
