Aiming at the degeneration phenomenon of images taken in mist, according to features of the drop quality image, this paper proposed a novel defogging algorithm based on improved atmospheric scattering model. The problem of fog-degraded images defogging restoration is transformed into the problem of optimization estimation for original un-degraded image by maximizing the global contrast object function, in this way, the proposed algorithm can restore the object image as completely as possible in probability sense. The experimental results show that the method can effectively improve the fog degeneration phenomenon and improve image clarity, significantly improving drop quality image visual effect.
