On the effectiveness of the Dark Channel Prior for single image dehazing by approximating with minimum volume ellipsoids

There is an increasing number of methods for removing haze and fog from a single image. One of such methods is Dark Channel Prior (DCP). The goal of this paper is to develop a mathematical explanation on why DCP works well by using principal component analysis, and minimum volume ellipsoid approximations.
