An Improved Image Restoration Model Based on General Total Variation
Xue Gang Fu, Yong Dong Xu · 2015
The diffusion function of Aubert TV model does not satisfy the second-best condition, we improve the diffusion function to get better image restoration results. Experiments results show that the new model overcome the staircase effect in smooth area and preserving significant image details in the high frequency area. This model gain higher peak signal noise ratio and has good performance of image restoration. KEYWORD: Total variation; Diffusion function; Image gradient; Image restoration
