The models were evaluated against phantom and pig brain data with known PpIX concentration; the supervised model achieved Pearson correlation coefficients (R values) between the known and computed PpIX concentrations of 0. 997 and 0. 990, respectively, whereas the classical approach achieved only 0. 93 and 0. 82.

With this knowledge, we introduce (1) a library of 9 endmember spectra, (2) a sparse, non-negative Poisson regression algorithm to perform physics-informed unmixing with this library without overfitting, and (3) a highly realistic spectral measurement simulation with known endmember abundances.

For tissue type, at least four of the five fluorophore abundances were found to be significantly different (p < 0. 01) between all classes.
