But I still am not able to use the above mentioned fucntions. Please help. Thanks. With OpenCV 3, the non-free modules, namely SIFT and SURF , which are patented by their respective creators, were moved out of the default OpenCV install and into the opencv_contrib package. The

I am using OpenCV 3.1.0 , Python 2.7.11 and Windows 10. I want to build the extra modules ( opencv_contrib ) into OpenCV. I follow the step in this GitHub . $ cd <opencv_build_directory> $ cmake -DOPENCV_EXTRA_MODULES_PATH=<opencv_contrib>/modules <opencv_source_directory> $ make -j5 When I type cmake _DOPENCV_EXTRA_MODULES_PATH=C:\opencv_contrib\opencv_contrib/modules C:\opencv\sources , there is an error . I am looking for help how can I solve it. Thank you. Tes3awy Update 29-5-2017: This also works with OpenCV 3.2.0-dev. Now using Visual Studio 2015 or 2017 gives no errors . The cv2.pyd is
