Leiber distance. The Kullback Leiber distance binary tree SVM(KLTSVM)
is applied for classification as well. In this experiment, the same training
and testing samples are used. The parameters are C=1024 and γ=0.5,
the classification accuracy is 93.82%, Kappa coefficient is 0.7682, and
time consumed is 0.9982 s. Comparing the results of two algorithms,
Fig. 7 shows that two methods could reach the same accuracy among
general objects. However, the results are different between road and
bare soil. We can reach the conclusion from Fig. 8, which is about the
spectral of road and bare boil in the experiment data set. Totally, JM distance
performs better for BTSVM than Kullback Leiber distance especially
in hyperspectral classification.
