By default, Mac uses default python 2.7
To run above commands, now, we are using python of brew version
Install OpenCV 3.0 using brew
brew install opencv3 --with-contrib --with-ffmpeg --with-java --with-python3 brew link opencv3 --force
To run with –with-python3, we install python3 version. java and ffmpeg is arbitrary.
We cannot use qt5 in Mac so far.
OpenCV is under /usr/local/opt/OpenCV
