Abstract
In one embodiment, an imaging method may include receiving an intensity value of a first spectral channel associated with a pixel location. The intensity value of the first spectral channel may be based on electromagnetic radiation reflected from an object after being emitted from a narrow-band electromagnetic radiation source. The method may further include defining an intensity value of a second spectral channel based on the intensity value of the first spectral channel. The second spectral channel may be associated with a spectral region of electromagnetic radiation different from a spectral region of electromagnetic radiation associated with the first spectral channel. The method may also include associating the intensity value of the second spectral channel with the pixel location.
