Extending color vision principles to display hyperspectral data has been investigated by researchers in recent past. However, color obtained by this approach (artificial color) is not used comprehensively for discriminating different materials. Especially, some of the interesting artificial color properties could be used effectively in this regard. We investigate such a case of impervious surfaces. Our hypothesis is: artificial color of impervious surfaces would be grey because of its spectral blandness over 350–2500 nm range. We investigate our hypothesis by performing chromatic discrimination analysis using artificial color of variety of urban materials. We use field spectra recorded by spectrometer, and spectra extracted from EO1-Hyperion image. Further, we filter these spectra by stretched CIE 1964 color matching functions to provide an artificial color to it. Analysis confirms our observations about the artificial color properties of impervious surfaces. Further it shows potential of artificial color to discriminate sub classes of impervious surfaces. |
