Abstract: In view of staircase effect occurred in total variation minimization methods and insufficient noise suppression,a new wavelet-based image inpainting algorithm was presented in this paper.The inpainting processing performs with optimizing an energy function of total variational norm and the l2norm,and finite difference method is adopted for finally established diffusion equation.The scheme has strong capability of keeping sharp edge mean,and staircase effect is weakened in smooth area.Experimental results which use different image show that the proposed method achieves better inpainting effect,especially when the wavelet coefficient is relatively high.
