Statistics shoud be computed on the same features as the one you use for the training (in your case you'll need mean and variance for all geometric features).
Note also that statistics are used to normalize samples between [0,1] to deal with features with different amplitude. Nevertheless this is not mandatory for all classifiers. For instead it is not mandatory for random forests classifier.
