Effect of calibration in the spectral signatures. (a) Grayscale image (generated by averaging each spectral band) and selecting pixels corresponding to different materials. (b) WR and DR spectral signatures. (c) Uncalibrated spectral signatures from the selected pixels. (d) Calibrated spectral signatures from the selected pixels. Colours in (c,d) correspond to selected pixels in (a).
