AFOD Regularization for Super-resolution Reconstruction

摘要：

In this paper, we present a new regularizationbased approach to construct a high-resolution image.The objective functional of the approach consists of a data fidelity term and a regularization term based on anisotropic fourthorder diffusion (AFOD) prior.To evaluate and prove the performance of the proposed method, series of experiments and comparisons with some existing methods including bi-cubic interpolation method and bilateral total variation method are carried out in the paper.Numerical results based on qualitative and quantitative evaluation can indicate that our algorithm is effective.
