Abstract

The acquired hyperspectral data are always in low resolution in both spatial and spectral domains, which will result in lots of mixed pixels and degrade the detection and recognition performance in civil and military applications. So many super resolution techniques are applied to overcome this limit. In this paper, we propose a coupled hyperspectral spatial super-resolution and spectral unmixing method based on sparse representation. Combing spatial super-resolution and spectral unmixing can precisely conserve both spatial information and spectral correlation among different bands. Spectral unmixing is taken as a regularization term in spatial super-resolution to test spectral consistency and avoid spectral distortion, while spatial super-resolution is used to enhance the resolution of abundance map after spectral unmixing.
