Abstract

Due to the tradeoff between spatial and spectral resolution in remote sensing imaging, hyperspectral images are often acquired with a relative low spatial resolution, which limits their applications in many areas. Inspired by recent achievements in convolutional neural network (CNN) based super resolution (SR), a novel CNN based framework is constructed for SR of hyperspectral images by considering both spatial context and spectral correlation. As a result, the spectral distortion incurred by directly applying traditional SR algorithms to hyperspectral images is alleviated. Experimental results on several benchmark hyperspectral datasets have demonstrated that higher quality of reconstruction and spectral fidelity can be achieved, compared to band-wise manner based algorithms.
