This paper presents a unified method for fast single image enhancement without using any extra information.Adopting a linear combination model of direct attenuation and un-uniform illumination, we describe a unified approach to handle such degraded images with a strategy that gracefully bridges the gap between those two extremes.The proposed approach simultaneously dehazes images and enhances sharpness by means of individual treatment of the RGB component of the residual images.Simulation results on a variety of outdoor degraded images demonstrate that the proposed method achieves short computation time and good restoration for visibility and color fidelity.
