Abstract

The software implementation of superresolution of subpixel-shifted satellite images is described in this paper. This software implementation is carried out as two independent (standalone) software modules: first one – for preliminary co-registering and integer-pixel cropping of input satellite imageset, and second one – for superresolution itself of subpixel-shifted satellite images, that are the first module output. Software modules are based on the correlation algorithms, statistical regularization, and filtering in frequency domain. Both modules are designed using advanced computing solutions. The developed modules were tested on actual satellite images and were demonstrated the quite sufficient resolution enhancement.
