Spectral Matching:
As an al-ternative to PCA, Spectral Matching may be used as a material identification method. This is particularly useful for large numbers of categories. Spectral Matching
compares the shape of each spectrum with each spectrum in the library and assigns a “degree of match” value ranging from ‑1 (perfectly anti-matched) to +1 (perfect
match) using a proprietary algorithm. The library entries that have the highest match values to the unknown sample are then used to identify the unknown.
