Hi,
In the transition guide to OpenCV 3 it says nonfree modules were removed, but I still found /usr/include/opencv2/xfeatures2d/nonfree.hpp in opencv-contrib. So I wanted to ask if this code really is nonfree, and if so, if there is a build parameter that can disable it's inclusion.
http://docs.opencv.org/master/db/dfa/tutorial_transition_guide.html https://github.com/Itseez/opencv_contrib/blob/master/modules/xfeatures2d/include/opencv2/xfeatures2d/nonfree.hpp
Note: I am already building with -DBUILD_opencv_nonfree=0
Thank you very much, Viktor
