Vision Enhancement in Bad Weather

Abstract

Road accident is a serious issue in most of the countries due to degraded visibility in bad weather such as fog, haze and rain. A better visibility is a key requirement for passenger's safety while maintaining the speed of the vehicle. Researchers throughout the world are focusing to enhance the visibility through bad weather mainly due to fog or haze to minimize accidents. Many efforts are being put up to clearly visualize the scene using computer vision. Classifications of fog and analysis of de-weathering techniques are prime motive of research. This book chapter addresses and summarizes the progress in the development of vision enhancement techniques for road safety in turbid medium, particularly with fog which greatly affects the vision. This chapter also presents a brief comparative analysis on different weather conditions and classification of fog which is important for application point of view.
