Figure 14

Classification maps of the PU dataset with directly combined features; (a)–(e), respectively, represent different groups of input features: spectral features, GF, TF, GF combined with TF, and all features along with the spectral features. is the feature dimension for input.
(a) SPEC
(b) GF
(c) TF
(d) GF + TF
(e) GF + TF + SPEC
