Ability of utilization of PCA in hyperspectral anomaly detection

Hyperspectral (HS) imaging is a complex way of taking the image of the scenery, where the rich spectral information is collected for any pixel of HS image. The rich spectral information can consequently be used for finding objects or identifying specific material in military utilization of HS imaging. Finding the objects as a spectral anomaly is one of specific tasks of HS image processing.
