Polarization descattering imaging through turbid water without prior knowledge

The traditional polarization imaging model needs to obtain the polarization information of backscattered light in advance, and is also not suitable for the recovery of the target with high polarization characteristics. In this work, the aforementioned shortcomings are overcame by adding the necessary constraints. Then, we propose a new method that can obtain the degree of linear polarization of the target and scattering medium simultaneously, and conduct a polarization descattering imaging experiment through turbid water. The images recovered by our method present the high contrast and similarity to the targets without scattering. Further, compared with other polarization underwater imaging strategies, this method is more suitable for the targets with different polarization characteristics and does not require any prior knowledge of target light or backscattered light.
