When capturing images of real-world environments, there are often many causes which can contribute to an impairment of visibility. One of these is the presence in the air of aerosols and water droplets that cause multiple scattering of light, which is observed in the form of fog, haze, or mist.
In this talk, the physical model of atmospheric scattering will be briefly introduced, then a general overview of the most effective methods for removing haze from images will be given. Finally, the weaknesses of such methods and some of the open problems will be discussed.
