This paper proposes a simple and effective algorithm for image enlargement, aims to improve upon the widely-used bilinear and nearest-neighbour interpolations for monitor displays. The proposed method uses nearest-neighbour interpolation to generate preliminary enlarged images, and selectively modifies only diagonal edges to reduce blocking artifacts. Experiments demonstrate the proposed method produces clear images with fewer artifacts across different enlargement factors and scenes.
