Abstract
The paper reports an application of Generalised Canonical Correlation
Analysis to fluorescence spectral data. Emission fluorescence spectra
can be recorded for several excitation wavelengths and can be presented
as 3-way data tables. The objectives of the data treatment are to describe
and compare the samples by taking into account all the emission spectra,
and to reveal characteristic excitation and emission wavelengths.
Generalised Canonical Correlation Analysis has been tested on fluorescence
emission spectra acquired for binary mixtures of raw materials in
the food domain. The application of the method within the context
of spectral data is presented.
