Dehaze the Image Using Directed Filter Method after Blind Dehazing

Abstract

Haze is generally phenomenon that an atmospheric stuff that greatly degrades the visibility of outdoor scenes. This phenomenon occurs due to the atmosphere constituent parts that absorb and scatter the light. We use the spread map of image in terms of intensity of image except a continuous region which has no edge information. The scheme performs a per-pixel manipulation, which is direct to implement, and then apply the Directed filter to improve the image quality. The simulation results demonstrate the comparative results and even better than the more complex state-of-the-art techniques, having the advantage of being appropriate for real-time applications.
