A robust hyperspectral image compression method is proposed for the detection of small target and abnormity. The virtual dimensionality of original data is estimated
then the endmember vectors are extracted using an unsupervised orthogonal subspace projection method. Fast-ICA transformation is performed with the endmember vectors as initialization matrix
and the IC images are coded by 2D Set Partitioning in Hierarchical Trees (SPIHT). The experiment results show that the algorithm has a high compression ratio (40∶1)
while the spectral characteristics are preserved. This algorithm is an efficient 3D compression method for the detection of small target and abnormity.
