In this paper, pansharpening methods suitable for the spatial enhancement of hyperspectral images are critically discussed and assessed on simulated data from the upcoming PRISMA mission, featuring a panchromatic camera mounted on the hyperspectral payload. Since most fusion techniques are limited to the fusion of multispectral (MS) images with panchromatic (Pan) images, the focus shall be on the extension of such methods towards hyperspectral (HS) images.

Abstract
In this paper, pansharpening methods suitable for the spatial enhancement of hyperspectral images are critically discussed and assessed on simulated data from the upcoming PRISMA mission, featuring a panchromatic camera mounted on the hyperspectral payload. Since most fusion techniques are limited to the fusion of multispectral (MS) images with panchromatic (Pan) images, the focus shall be on the extension of such methods towards hyperspectral (HS) images. In particular, the impact of the bandwidth of Pan on fusion performances will be analyzed and discussed. © 2013 SPIE.File in questo prodotto:
