Choose (a spatial/spectral subset of) a multi- or hyperspectral image in
the first dialog. Then select the number of training samples fo r the kernel
matrix (sele ct 0 to deter mine them with the K-means algorithm). Next, enter
the NSCALE parameter for the Gauss ian ker ne l (the Gaussian kernel para meter
γ is calculated as in Equation (C.1)), and finally the output destination for
