Paper Abstract
Digital superresolution (DSR) is the process of improving image resolution by overcoming the sampling limit
of an imaging sensor, while optical superresolution (OSR) is the recovery of object spatial frequencies with
magnitude higher than the diraction limit of the imaging optics. The present paper presents an integrated,
Fisher-information-based analysis of the two superresolution (SR) processes applied to a sequence of sub-pixel
shifted images of an object whose support is precisely known. As we shall see, prior information about the
object support makes it possible to achieve OSR whose delity in fact improves with increasing size of the image
sequence. The interplay of the two kinds of SR is further explored by varying the ratio of the detector sampling
rate to the Nyquist rate.
