Method Detail

unmix

double[][] unmix(double[][] spectra)

Performs a linear spectral unmixing of a set of spectra.

Parameters:

spectra - the spectra, where number of rows = number of spectral channels number of cols = number of spectra

Returns:

the abundances, where number of rows = number of endmembers number of cols = number of spectra

mix

double[][] mix(double[][] abundances)

Calculates the spectra for a set of abundances.

Parameters:

abundances - the abundances, where number of rows = number of endmembers number of cols = number of spectra

Returns:

the resulting spectra, where number of rows = number of spectral channels number of cols = number of spectra
