Aerial Polarization-Imaging System and Method for Detection of Subsurface Fish

An aerial polarimetric fish-detection system and method acquire polarization-resolved imagery from an elevated platform over a water area, compute per-pixel polarization metrics (degree and angle of linear polarization), compensate for viewing geometry and environmental factors, and detect candidate subsurface scatterers consistent with fish via spatial and temporal anomaly analysis. The system geolocates candidate fish positions, estimates confidence and depth proxies, and add more details about how the polarization may happen to allow seeing below the surface and reducing glare.
