How to create "trained_classifierNM1.xml"?

For text detection, the cpp_file( opencv_contrib/module/text/example/textdetection.cpp) loads "trained_classifierNM1.xml" and "trained_classifierNM2.xml" to create 2 classifer. Does any body know which training set was used to create them?

As far as I know, "trained_classifierNM1.xml" was created by boost with some features, and "trained_classifierNM2.xml" was created by SVM.

thanks in advance!
