Depolarization index from Mueller matrix descatters imaging in turbid water

Polarization underwater imaging is of great potential to target detection in turbid water. Typical methods are challenged by the requirement on degrees polarization (DoPs) both light and backscattering. A descattering method was developed using Mueller matrix, which turn derived a depolarization (Dep) index from matrix characterize scattering media estimating transmittance map combining optimal function. By quantifying attenuation with map, clear vision targets can be recovered. Only information media, under diverse water turbidity enhanced results experimental data.
