1. A method of generating an intrinsic hyper-spectral image of a field of view of interest, said method comprising:
scanning a field of view of a reference surface with and without a diffuse material between a camera lens of a hyper-spectral imaging device and said field of view of said reference surface to generate diffused and focused calibration data cubes of said reference surface, respectively;
subtracting, pixel by pixel, the diffused calibration data cube of said reference surface from the focused calibration data cube of said reference surface to generate a residual calibration data cube;
scanning a field of view of interest with and without a diffuse material between said camera lens and said field of view of interest to generate diffused and focused data cubes of said field of view of interest, respectively;
adding said residual calibration data cube to the diffuse data cube of the field of view of interest to generate a resulting data cube;
and subtracting said resulting data cube from the focused data cube of the field of view of interest to generate an intrinsic data cube of the field of view of interest.
