Resolution Enhancement of Hyperspectral Imagery

Abstract

Resolution enhancement is a key technology that can expand the range of potential applications for spaceborne hyperspectral missions. This paper provides an overview of resolution enhancement techniques for hyperspectral imagery, namely, hyperspectral superresolution, subpixel mapping, hyperspectral pansharpening, and hyperspectral and multispectral data fusion. The paper describes the potential and limitations of each technique from the viewpoint of practicality.
