By doing this, the user can see how much of the image
is likely to be put into the class associated with the signature.
+wxIClass can also import training areas defined in a vector layer. In that case the program expects the vector layer to have the following columns defined:
+
+ - cat: category value
+ - class: a string with the class name
+ - color: a color defined using a with format "RRR:GGG:BBB"
+

The spectral signatures are composed of region means and covariance matrices.
These region means and covariance matrices are used in
