Latest Patents

Marcotte is associated with 1 patent, titled “Prior-Knowledge-Based Spectral Unmixing Methods.” The invention describes a method for separating spectral data into contributions from multiple sources. It models the data with an endmember matrix, representing the spectra of the sources, and an abundance matrix, indicating each source’s contribution to each measured spectrum. The method incorporates external prior spectral information about both matrices to guide the unmixing process. One potential application is calibrating spectral detection systems, including scintillator-based fiber dosimeters.
