| 2 | An Adaptive Strategy for the Restoration of Textured Images using Fractional Order Regularization显示文摘Total variation regularization has good performance in noise removal and edge preservation but lacks in texture restoration.Here we present a texture-preserving strategy to restore images contaminated by blur and noise.According to a texture detection strategy,we apply spatially adaptive fractional order diffusion.A fast algorithm based on the half-quadratic technique is used to minimize the resulting objective function.Numerical results show the effectiveness of our strategy. | R.H.Chan A.Lanza S.Morigi F.Sgallari | 2013 | Numerical Mathematics(Theory,Methods and Applications)2013，6，1： | 0 |
