主 题:single image dehazing decomposition strategy image processing global atmospheric light
摘 要:Outdoor haze has adverse impact on outdoor image quality,including contrast loss and poor *** this paper,a novel dehazing algorithm based on the decomposition strategy is *** combines the advantages of the two-dimensional variational mode decomposition(2DVMD)algorithm and dark channel *** original hazy image is adaptively decom-posed into low-frequency and high-frequency images according to the image frequency band by using the 2DVMD *** low-frequency image is dehazed by using the improved dark channel prior,and then fused with the high-frequency ***,we optimize the atmospheric light and transmit-tance estimation method to obtain a defogging effect with richer details and stronger *** proposed algorithm is com-pared with the existing advanced *** results show that the proposed algorithm has better performance in comparison with the state-of-the-art algorithms.
