It was first proposed by Michal Irani in her 1991 paper "Improving resolution by image registration". The imaging model being used is described by a paper by Michael Elad, "Super-Resolution Reconstruction of an image". Both papers can easily be found through a search in Google Scholar. I've done two simplifications to the imaging model: 1) The image blur is assumed to be spatially invariant. 2) The spatial transformation model is a global translation. To run the example code, follow the following steps: 1) Run SRSetup.m 2) Run SRExample.m The example code operates on a dataset that is generated synthetically from a reference image. Thus, the exact values for the blur sigma and the translatoin offsets are being used.
