Real radiometrically corrected hyper spectral image of a Rome city area as provided by the Airborne Laboratory for Environmental Research at IIA-CNR in Rome, Italy [19]. This 540×337 pixels image was obtained with an airborne imaging spectrometer containing 102 channels. The RGB version (left-upper), the classification map or ground-truth considering pure pixels (left-bottom) and the nine material abundances (67×42 pixels) computed by using a 8×8 window (right) are shown.
