Abstract

Super-resolution is a set of methods of increasing or doubling image resolution. Super-resolution algorithms can be divided into frequency or space domain. In this paper, a simple technique shall be applied in both space and frequency domain of an image. This transform integrates a simplified mathematical framework technique using matrices, as well as a block-wise reconstruction technique. Tchebichef moment has been chosen here since it performs better than the popular Discrete Cosine Transform.
