A Frequency-Limited Study of Chromaticity Characteristics for Reflectance Spectra

摘要

Reflectance spectra of hyperspectral images of the natural scenes are supposed to represent the real world better than any certain classes of natural and man-made spectral reflectance data sets such as rocks, leaves, Munsell chips, etc. In this paper, spectral reflectance data sets from hyperspectral images which represent natural scenes were formed. These data sets' chromaticity characteristics and frequency-limited properties were analysed, in which various classes of physically measured natural or man-made surface reflectance functions were investigated. The result shows that in general, there appears to be more constraints for natural reflectance spectra than artificial man-made reflectance spectra.
