Installing Opencv With Contrib Modules

I was running python3.6 (32 bit) with opencv3.3.1. I saw this tutorial so I was trying out the brute force matching with SIFT descriptors: http://opencv-python-tutroals.readthedoc

Solution 1:

For enabling opencv-contrib modules, you have to rebuild your opencv lib from source. In CMake config, you have to enable it, specifying variable OPENCV_EXTRA_MODULES_PATH with path where you have opencv_contrib modules such as ...wherever_you_downloaded_it/opencv_contrib/opencv_contrib-master/modules.

Then, building opencv with make will build modules, and make install will install these libs with other opencv libs.
