Image Interpolation by Super-Resolution
Alexey Lukin, Andrey Serdjevich Krylov, Andrey V. Nasonov · 2006
Term “super-resolution ” is typically used for a high-resolution image produced from several low-resolution noisy observations. In this paper, we consider the problem of high-quality interpolation of a single noise-free image. Several aspects of the corresponding super-resolution algorithm are investigated: choice of regularization term, dependence of the result on initial approximation, convergence speed, and heuristics to facilitate convergence and improve the visual quality of the resulting image.
