Abstract
If compared with panchromatic ones, satellite multi-spectral images present better spectral but lower geometric resolution. True colour compositions RGB that are obtained using red, green and blue wavelength bands, are characterized by pixel dimensions of multi-spectral images. With Pan-Sharpening techniques these compositions derive the same geometric resolution of panchromatic data. In this paper some Pan-Sharpening techniques are considered in relation to their application to IKONOS images. Attention is focalized on those based on IHS (Intensity, Hue, Saturation) model. Applications are conducted on clipped imagery of IKONOS concerning Campania Region and the results are analyzed and compared.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
