Fig. 1

The stages of generating the synthetic XRF spectra for model training. A synthetic spectrum for the iron earth pigments class is shown (a) as output by the FP method, (b) with Gaussian peaks defined using the fano factor and noise of the detector, and (c) after accounting for the energy-dependent device sensitivity. (d) Acquired XRF spectrum for an iron earth paint sample
