In this paper, a detailed survey study on single image super resolution SR has been presented, which aims at recovering a high resolution HR image from a given low resolution LR one. It is always the research emphasis because of the requirement of higher definition video displaying, such as the new generation of Ultra High Definition UHD TVs. Super resolution SR is a popular topic of image processing that focuses on the enhancement of image resolution. In general, SR takes one or several low resolution LR images as input and maps them as output images with high resolution HR , which has been widely applied in remote sensing, medical imaging, biometric identification.
