Paper Abstract

We study the nonlocal total variation (NL-TV) regularization technique for image zooming, which exploits the spatial interactions in images. To solve the nonlinear Euler-Lagrange equation associated with the NL-TV regularization framework, we propose a split Bregman NL-TV image-zooming method. Furthermore, we give the convergence analysis of the proposed algorithm. Experimental results illustrate the effectiveness and reliability of our method by comparing it to some previous methods.
