中文摘要：

文章提出了新的雾天偏振成像模型,在模型中同时考虑目标反射光和大气散射光的偏振效应。首先合成偏振差分图,然后利用去相关的算法估计目标反射光的偏振度图,最后利用去雾模型得到清晰的雾天图像。与相关算法的实验结果进行定性和定量的比较,证明了该算法的有效性。此外,该算法求取的反映场景目标偏振信息的偏振度图可被用于场景分割、目标识别等领域。

英文摘要：

In this paper,a new polarization hazy imaging model is presented,which considers the polarization of the airlight and the object radiance jointly.Firstly,the polarization-difference image is synthesized.Then the polarization of object is separated by a decorrelation-based method.Finally,the haze-free image is effectively recovered based on the new polarization imaging model.The qualitative and quantitative experimental results verify the effectiveness of the proposed dehazing method.The method also provides additional polarization properties of the objects in the scene,which can be used in further applications,such as scene segmentation and object recognition.
