For a review, see [32]. Specific applications require the design of image analysis
algorithms, some of which may require the use of both spectral and image
features [33, 34]. Spectral image analysis, in itself, is a growing field, and some
of the basic algorithms are described here.
13.3.1 Calibration for Multispectral
Image Acquisition
A key utility of multispectral microscopy is its ability to characterize the inher-
ent chemical properties of a sample. This is achieved by measuring the sample’s
spectral response. In imaging any composite biological material, the interpre-
tation of the spectra is a complicated problem. A primary reason for this is
