Single-frame super resolution image embedding

The multi-frame super resolutions have an admirable mathematical formulations and justification to combine the information of manifold LR images to get a HR one. Furthermore it has direct application for spatial video Super Resolution. Theoretically and sometimes for real images under global transformation those algorithm produces excellent results. However, in real circumstances most of the cases it fails to attain image quality up to that mark. Moreover, sometimes number of LR frame available is very low, or in most of the cases only one LR frame is available. Hence, in recent years single frame super resolution is attracting the consideration of more researchers.
