Claim:
A method comprising the steps of: (a) providing a sample document; (b) obtaining a digital image of said sample document; (c) treating said sample document with ninhydrin; (d) illuminating said sample document to thereby produce a first plurality of interacted photons wherein said first plurality of interacted photons are selected from the group consisting of: photons scattered by said sample document, photons reflected by said sample document, photons absorbed by said sample document, photons emitted by said sample document, and combinations thereof; assessing said first plurality of interacted photons to thereby generate a hyperspectral image representative of said sample document; (e) analyzing said hyperspectral image to thereby identify at least one region of interest of said sample document; and (f) obtaining a hyperspectral image of at least one of said regions of interest, wherein steps (b)-(d) are automated using robotics.
