I have been playing around with image recognition on opencv and I understand Surf/sift have been moved to xfeature2d in the 3.X.X versions of opencv. I have tried to compile the contrib files through Cmake but it always shows errors. I am wondering if there was another way to obtain xfeature2d, maybe through purchasing the license?
Hei, you do not have to purchase the license if all you want is try/test/use them for personal projects (maybe for commercial purpose you should look carefully). It seems that you failed just because of the compile stage, maybe a better tutorial is enough. See OpenCV 3 Tutorials, Resources, and Guides, especially the Ubuntu 16.04: How to install OpenCV if you are under ubuntu. I even follwoed it installed opencv(2/3) on windows successfully.
And what is more, Wrapper package for OpenCV python bindings. is pretty impressive, if you do not have to use C++ and python is enough, you do not have to compile and install opencv at all, and it's cross-platform.
