Satellite Imagery Spectral Bands Subpixel Equalization Based on Ground Classes’ Topology

The technique of multispectral images processing for the spatial resolution equalization is presented. Land cover fuzzy logic classification using ground-truth spectral signatures measurements is performed. Spatial topology relationships were taking into account. Basic types of subpixel connection are allocated. Multiple-valued logic mathematical approach was used for make a decision about class changing according to class similarity matrix. Analysis by modulation transfer function demonstrates increase in physical resolution of the original image after equalization.
