Abstract: In order to reduce the influence of fog weather on the outdoor imaging system, this paper proposes an improved dark original prior image defogging method. First, the analysis of the imaging mechanism of haze weather images is made. Then we make a simple introduction and objective analysis on the traditional dark original prior defogging principle and algorithm, and make some optimization and improvement. Finally, simulation experiments are took for fog images using various algorithms. The results show that, the method can significantly improve the definition and contrast ratio of the original image.
