Decision Trees - nodes info

edit

Hi guys,

I was wondering how to get the info about the condition in every division node in decision trees classifier (CvDTree)? After training the tree .xml file can be saved. It contains the trained model, but I can't interpret it. Maybe someone could explain it to me. Or maybe there is another way to get that node info?

My case is: 8 features, 13 classes, 100 samples per class, OpenCV 2.4.8, C++. And here is the .xml:
