Abstract:
To monitor biological systems, aside destructive testing which have been developed in chemistry and chromatography, hyperspectral image acquisition and processing exhibit the great advantage of being non-destructive. In this paper, a hyperspectral image acquisition setup is proposed, to get detailed information on the reflectance of leaves. We aim at giving information about the repartition of pigments on a leaf, by proposing a hyperspectral image acquisition setup, and adapting an algebraic method, vertex component analysis, which selects, among a set of input spectra, the marker spectra which best yield all input spectra by linear combination. A matrix inversion yields the contribution of the marker spectra for any spectrum. We acquired the image of leaves and estimated pigment concentrations with the help of a reflectance index.
