摘 要:雾霾导致的图像质量退化、图像可视性降低,给交通运输、视频监控乃至军事侦察等带来很大的困难。现有去雾方法的算法复杂度较高,无法满足实时监测或侦察的需求。针对此问题,提出了一种基于偏振成像的快速去雾算法,在大气散射成像模型的基础上,通过合理假设并充分利用偏振探测优势,有效降低了算法复杂度,能够在更短的处理时间内取得与暗通道方法相似的去雾效果,可以广泛应用于实时去雾监测与侦察领域。

Abstract: Due to the influence of haze weather, the quality and visibility of image are seriously degraded, which will bring great difficulties to traffic transportation, video surveillance and even military reconnaissance. The existing defogging methods have a higher algorithm complexity and cannot meet the needs of real-time monitoring or reconnaissance. Aiming at this problem, a fast defogging algorithm based on polarization imaging is proposed. On the basis of the atmospheric scattering imaging model, through the reasonable hypothesis and make full use of the advantages of polarization detection, the proposed algorithm can effectively reduce the algorithm complexity and obtain the similar defogging effect with dark channel method in a shorter processing time. It can be widely used in the realtime defogging monitoring and reconnaissance field.
Keywords: polarization imaging; defogging; atmospheric scattering imaging
