klt_train determines the KLT transform (mean vector and transform matrix) for the given ICB-format file icbfile. The resulting KLT is written to kltfile, a KLT-format file. This KLT provides a transform for spectral decorrelation of the hyperspectral image in icbfile; the KLT training is accomplished via a call to QccHYPkltTrain(3) .
See icbklt(1) and icbiklt(1) to apply klt to the dataset as a forward transform or inverse transform, respectively.
