一种快速的单幅图像去雾算法
A Fast Effective Single Image Dehazing Algorithm
摘要
Abstract
A fast and effective single image dehazing algorithm is proposed in order to solve the problems of low efficiency 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 show that the proposed algorithm has high efficiency,which can effectively improve the visibility and contrast of the restored image.关键词
