Introduction to Hyperspectral Image Analysis
spacejournal.ohio.eduSpectral analysis methods usually compare pixel spectra with a reference spectrum (often called a target). Target spectra can be derived from a variety of sources, including spectral libraries, regions of interest within a spectral image, or individual pixels within a spectral image.
