Abstract

The disclosure relates to method and apparatus for interactive hyperspectral image subtraction. In one embodiment, the disclosure relates to a method for obtaining a spectral image of a first specie from a frame of a plurality of pixels defining a composition ~f the first specie with a second specie. The method may include (i) identifying, for each of the first and second species, an appropriate Raman wavelength; (ii) defining at least owe background wavelength for the frame; (iii) identifying pixels defied oily by background wavelength; (iv) identifying pixels defined only by the first specie or the second specie; (v) identifying the remaining pixels, the remaining pixels defined by at least a combination of the first and second species; and (vi) forming a spectral image for the first specie.
