“…Polarization imaging has been well documented for its excellent recognition capabilities in applications, such as object detection, 26 transparent object detection, 27 and background segmentation 28 . Polarization images can obtain physical properties of objects that cannot be detected by conventional imaging, such as degree of polarization, roughness, and other special properties 29 . In underwater scenes, due to the interaction of a light wave with an object, the polarization information can differ significantly depending on the object material, surface roughness, geometry, and so on, which enhances the detection of the target compared with traditional optical images.…”
