Several methods exist that try to remove haze from a single image but they lack in the support for why a particular method was chosen. The idea of using color ellipsoids is presented in this paper for the purpose of developing a new framework for analyzing single image dehazing methods. Synthetic and real world images are used to support important properties of the color ellipsoids that give a queue...
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.
