Claim 6:
7. The method according to claim 1 wherein the first augmentation algorithm comprises:
(a) selecting a pixel to be augmented from the hyperspectral image;
(b) decomposing spectral bands to identify eigenvectors and eigenvalues, wherein the spectral bands correspond to a spectral signature of the pixel;
(c) selecting a largest eigenvalue for the pixel;
(d) augmenting the pixel by multiplying the selected largest eigenvalue by a random scaling factor; and
(e) selecting a next pixel to be augmented from the hyperspectral image, wherein the next pixel is different from a previously augmented pixel and repeating steps (b), (c), (d) and (e) until all pixels of the hyperspectral image are augmented.
