Abstract

Anisotropic Total variation (ATV) based super resolution method is a state-of-the-art method, which is popularly used. However, the traditional ATV based method is a kind of local method, which is just considered its 4 or 8 neighborhood of each pixel, without considering a larger region. In this paper, we proposed a non-local based ATV method (NLATV), which considers a larger region of each pixel. The experimental results show that the proposed method is much better than the original ATV method in peak signal-to-noise radio and visual quality.
