Multi-frame Blind Deconvolution with Non Local Total Variation Regularization

摘要

We consider the recovery of multi-frame degraded images without complete knowledge about the degradation. A variational method is applied to simultaneously reconstruct the original image and the associated PSFs. In order to alleviate the concerns of noise amplification while preserving sharp edges and fine structures, nonlocal total variation regularization is used on images. An efficient numerical scheme is proposed to solve the variational problem. Numerical results are used to show the performance of the proposed method.
