In the process of haze removal by the polarization method, it is very important to obtain accurate polarization information. On the one hand, the influence of noise can be effectively suppressed by appropriately weighted amplifying the airlight degree of polarization and the airlight corresponding to an object at an infinite distance. On the other hand, the scattering energy in channels B and G is larger, so it can reflect the actual polarization information violently. Analysis indicates the appropriately weighted amplification for the airlight degree of polarization in these two channels that can improve their estimation accuracy to a certain extent, it makes the color of the restored images more natural, and the details of the images are also more abundant. Moreover, in some special scenes, the polarization of the direct transmission could not be ignored on account of its important contribution to the total polarization. Hence, when the polarization of the direct transmission needs to be involved, only the polarization of direct transmission that contributes significantly to the total polarization is considered, and the polarization of the direct transmission in other scenes is ignored. This can still effectively eliminate the color distortion of the special scenes in the recovery results, and can greatly reduce the time consumption.

优化偏振去雾

在偏振法去雾过程中，获取准确的偏振信息非常重要。一方面，通过适当加权放大空气光偏振度和无限远物体对应的空气光，可以有效抑制噪声的影响。另一方面，通道中的散射能量乙和G较大，因此可以强烈地反映实际的极化信息。分析表明，对这两个通道的空气光偏振度进行适当的加权放大，可以在一定程度上提高其估计精度，使恢复图像的色彩更加自然，图像的细节也更加丰富。此外，在一些特殊场景下，直接传输的极化对全极化的贡献也不容忽视。因此，当需要涉及直接传输的极化时，只考虑对总极化贡献显着的直接传输的极化，而忽略其他场景中的直接传输的极化。
