Since foggy days are hard to forecast, the probability of a traffic accident happening on these days will be several times more than that on the usual days, highly reducing the traffic safety and greatly causing economic losses. In addition, dense fog is the main cause of multiple vehicle collision accidents. Since the traffic monitoring technique has been widely used in the traffic management, removing fog from the traffic video has become the hot research topic in recent years. First, this paper reviews the retinex method, commonly used to remove the fog in the traffic management. Then, it proposes the improved retinex-based method to remove the fog in the traffic video. Experiment results show that the proposed method can not only remove the fog but also enhance the clarity of the traffic video image.
