Abstract
Pansharpening refers to the fusion of a low spatial resolution multispectral image and a high spatial resolution panchromatic image in order to have a synthesized (fused) product with the same spatial resolution of the panchromatic image and the same spectral resolution of the multispectral data. In this work, the problem of fusing the entire set of bands acquired by the WorldView-3 sensor from the visible spectrum to the short-wave infrared spectrum is addressed. In particular, the goal is to enhance the spatial resolution of all the visible, near-infrared, and short-wave infrared bands in order to reach the spatial resolution of the panchromatic image. A framework is proposed exploiting the multispectral image at middle spatial resolution to improve the performance (which is assessed on both simulated and real WorldView-3 data) of the fusion between short-wave infrared and panchromatic data.
