1. A system, comprising:
a first camera device operable to capture a plurality of images of a scene at a first band of wavelengths;
a second camera device operable to capture a plurality of images of the scene at a second band of wavelengths, wherein the first and second bands are different; and
a processor communicatively coupled to the first and second camera devices, the processor being operable to detect an object in the scene based on a first image of the plurality of images from the first camera device and based on a first image of the plurality of images from the second camera device that was captured at substantially a same time as the first image from the first camera device, to estimate an obscurant in the scene based on the first image from the first camera device and the first image from the second camera device, and to estimate a visibility of the scene based on the object and the estimated obscurant,
wherein the first band of wavelengths comprises visible light, the second band of wavelengths comprises long wave infrared light, and the first camera device is a polarization sensitive camera device operable to capture full Stokes polarization.
