This paper focuses on reducing the computational cost of a GNC Algorithm for deblurring images when dealing with full symmetric Toeplitz block matrices composed of Toeplitz blocks. Such a case is widespread in real cases when the PSF has a vast range

Introduction: In this paper, we deal with the demosaicing problem when the Bayer pattern is used. We propose a fast heuristic algorithm, consisting of three parts. Methods: In the first one, we initialize the green channel by means of an edge-directe

We examine an instance of the blind source separation problem, namely, the reconstruction of digital documents degraded by bleed-through and show-through effects. We introduce a nonstationary, loca...

The problem of image restoration from blur and noise is studied. By regularization techniques, a solution of the problem is found as the minimum of a primal energy function, which is formed by two terms. The former deals with faithfulness to the data

We consider the problem of restoration of images corrupted by blur and noise. We find the minimum of the primal energy function, which has two terms. The former is related to faith fulness to the data and the latter is associated with smoothness cons

The problem of image restoration from blur and noise is studied. A solution of the problem is understood as the minimum of an energy function composed by two terms. The first is the data fidelity term, while the latter is related to the smoothness co

The Symmetric Circulant Travelling Salesman Problem asks for the minimum cost tour in a symmetric circulant matrix. The computational complexity of this problem is not known – only upper and lower bounds have been determined. This paper provides a
