Abstract
ABSTRACT The polarization information of incident light gets lost after passing through the scattering medium such as haze. This phenomenon, called depolarization, poses a challenge to polarization remote sensing of ships in sea-haze weather. In this paper, we propose the concept of ship polarization information restoration for the first time and propose a ship polarization information restoration method for the benefit of ship remote sensing in sea haze weather. The approach is based on the estimation of airlight, a component of hazy polarimetric images. To demonstrate the effectiveness of the proposed ship polarization information restoration method, we conduct an outdoor experiment on ship polarization information restoration in sea haze weather. Experimental results show that sea haze significantly degrades the degree of polarization of ships, but slightly affects the angle of polarization. In addition, the degree of polarization of ships becomes more prominent after polarization information restoration.
