Multivariate Spectral Analysis to Extract Materials from Multispectral Data
Abstract
This effort investigates various multivariate analysis techniques for classification/identification to extract natural and manmade features reliably from broad-band spectral imaging data/multispectral imagery. An enhanced Bayesian method is proposed and is demonstrated to exhibit increased accuracy over three conventional supervised classifiers. Broad-band spectral properties of various materials are examined and the perturbations on spectra of pure materials introduced by mixtures are shown. A mixing model that uses multiple linear regression constrained by two physical properties is tested.
