Classification: CPC A  G | IPC A  G

Claim 0:
1. A method for quantifying a biomarker of a tissue, the method comprising:
receiving data comprising light reflectance data from the tissue at a plurality of wavelengths within a main wavelength interval acquired by an imaging sensor;
determining, using a processor, at least two spectral sub-intervals within the main wavelength interval in a manner such that a combination of the light reflectance data in the at least two spectral sub-intervals is correlated with a clinical variable of interest;
receiving, at least one spectral confounder present in the tissue causing a spectral variability in the light reflectance data;
extracting spectral features related to the spectral confounder from the light reflectance data; and
calculating a measure of the biomarker of the tissue using the light reflectance data in the at least two spectral sub-intervals using the processor;
wherein the main wavelength interval is broader than each of the at least two spectral sub-intervals.
