Images taken in scattering media, such as haze, fog, and underwater, often look faded and lack contrast. We detect changes in pixels' distribution in RGB space due to the scattering medium: instead of tight clusters the pixels form lines, which we term Haze-Lines. In this talk the model will be introduced, and two applications will be discussed. First, estimating the air-light: the color of a pixel with no object in the line of sight. Second restoring the colors of underwater images, where the model is expanded to incorporate the spectral non-uniformity.
