Image Super-resolution

Super-resolution is the task of obtaining a high-resolution image of a scene given low resolution image(s) of the scene. Applications of super-resolution include forensic, satellite, medical imaging, surveillance, displaying video on large screens, etc [1]. Obtaining high-resolution images directly via better hardware (better image sensors, larger chip size) is quite costly. Furthermore, most of the smart-phones today would be hard-pressed to incorporate hardware enhancements for achieving high resolution images. Hence, a signal processing approach to increase the resolution of images obtained from the phone camera is desirable.
