Claim 7:
8. The method according to claim 1, wherein the second augmentation algorithm comprises:
(A) selecting a pixel to be augmented from the hyperspectral image;
(B) decomposing spectral bands to determine a covariance matrix, wherein the spectral bands correspond to a spectral signature of the pixel,
(C) computing a multivariate normal distribution, around a mean value of each spectral band, using the covariance matrix,
(D) scaling the multivariate normal distribution by multiplying with an optimisable magnitude parameter;
(E) adding the scaled multivariate normal distribution to the pixel for augmenting the pixel
(F) selecting a next pixel to be augmented from the hyperspectral image, wherein the next pixel is different from previously augmented pixel and repeating steps (B), (C), (D) and (E) until all pixels of the hyperspectral image are augmented.
