Abstract

It is shown that the band-limit spectrum of a nonnegative image is represented as the auto-convolution of a spectrum whose cutoff is half of the band limit. The relation between the nonnegative image and its spectrum is used to construct a phase retrieval method and a superresolution method. Computer simulation results of these methods are shown.
