ABSTRACT
This is a problem encountered in a plethora of applications. Images and video of higher and higher resolution are required, for example, in scientific (medical, space exploration, surveillance) and commercial (entertainment, high-definition television) applications. One of the early applications of high-resolution imaging was with Landsat imagery. The orbiting satellite would go over the same area every 18 days, acquiring misregistered images. Appropriately combining these LR images produced HR images of the scene.
