Abstract: Combining variational partial differential equation with the atmospheric attenuation model,a single color ima-ge dehazing algorithm on the basis of dark channel prior and MTV model called H-MTV model was proposed.Then,using auxiliary variables and Bregman iterative parameters to calculate the model,this paper designed dual Bregman algorithm.Finally, H-MTV model was compared with He algorithm and Kimmel Retinex algorithm.Experimental results show that H-MTV model is superior to the traditional methods qualitatively and quantitatively.

Key words: Color image dehazing,Dark channel prior,MTV model,Dual Bregman algorithm
