Efficient and Effective Total Variation Image Super-Resolution: A Preconditioned Operator Splitting Approach
Super-resolution is a fusion process for reconstructing a high-resolution image from a set of low-resolution images. This paper proposes a novel approach to image super-resolution based on total variation (TV) regularization. We applied the Douglas-Rachford splitting technique to the constrained TV-...
