A Fast Effective Single Image Dehazing Algorithm

LIU Jie-ping;HUANG Bing-kun;WEI Gang;School of Electronic and Information Engineering,South China University of Technology;  
A fast and effective single image dehazing algorithm is proposed in order to solve the problems of lowefficiency and the color distortion of the bright grey areas after dehazing algorithm of using dark channel prior. First,the algorithm estimates the rough transmittance and the atmospheric light based on HSI color space. Then,the final transmittance is generated after smoothing the rough transmittance by guided filter and correcting the transmittance of the bright grey areas by a threshold method. Finally,tone mapping are used to get the restored image. Experiments showthat the proposed algorithm has high efficiency,which can effectively improve the visibility and contrast of the restored image.
