We also need to update our PKG_CONFIG_PATH environment variable to make sure it knows where opencv3.pc is located.
We need to copy the pkg-config file “opencv.pc” to “/usr/local/lib/pkgconfig” and name it “opencv3.pc” so that it doesn’t conflict with our existing OpenCV 2.4.x config file: $ cp /path/to/opencv-3.0.0/build/lib/pkgconfig/opencv.pc /usr/local/lib/pkgconfig/opencv3.pc If you want to make it permanent, just add the following line in your “~/.profile” file: export DYLD_LIBRARY_PATH=/path/to/opencv-3.0.0/build/lib:$DYLD_LIBRARY_PATH We are not done yet! Let’s set the library path: $ export DYLD_LIBRARY_PATH=/path/to/opencv-3.0.0/build/lib:$DYLD_LIBRARY_PATH The “-j4” flag indicates that it should use 4 cores. Make sure you are inside the directory “/path/to/opencv-3.0.0/build” and run the following commands: $ make -j4 OPENCV_EXTRA_MODULES_PATH : This flag indicates that OpenCV should compile the extra modules (opencv_contrib) that we downloaded earlier.BUILD_EXAMPLES=ON : This flag indicates that we want to compile the included OpenCV examples.INSTALL_PYTHON_EXAMPLES : This flag indicates that the Python examples need to be installed after compilation.INSTALL_C_EXAMPLES : This flag indicates that the C/C++ examples need to be installed after compilation.PYTHON2_INCLUDE_DIR : This is the path to Python header files for compilation.PYTHON2_LIBRARY : This is the path to your brewed Python (Hombrew installation of Python).CMAKE_INSTALL_PREFIX : This is the directory where OpenCV 3.0.0 will be installed.CMAKE_BUILD_TYPE=RELEASE : We are telling cmake that we are building a “release” version of OpenCV.Let’s take a moment to understand what these flags mean exactly: $ cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/path/to/opencv-3.0.0/build -D PYTHON2_LIBRARY=/usr/local/Cellar/python/2.7.9/Frameworks/amework/Versions/2.7/bin -D PYTHON2_INCLUDE_DIR=/usr/local/Frameworks/amework/Headers -D PYTHON2_PACKAGES_PATH=/usr/local/lib/python2.7/site-packages -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D OPENCV_EXTRA_MODULES_PATH=/path/to/opencv_contrib-3.0.0/modules. Run the following commands from you terminal: $ cd /path/to/opencv-3.0.0/

Bear in mind that some of them are not free for commercial use, but it is great tool to learn new algorithms. It is basically a repository that contains state of the art algorithms. If you see “/usr/local/bin/python” printed on your terminal, you can proceed.ĭownload OpenCV 3.0.0: You can download it from here.ĭownload “opencv_contrib”: As discussed earlier, we can use the latest computer vision algorithms from “opencv_contrib”. Run the following command from your terminal: $ which python Let’s confirm that you are using brewed Python.
Run the following command to do it: $ source ~/.profile We need to reload the file to update the environment variables. Open up your ~/.profile file and add the following line: export PATH=/usr/local/bin:$PATH Now that Homebrew is installed, let’s update it and install Python: $ brew update If you don’t have Homebrew, you can install it using the following command: $ ruby - e "$(curl -fsSL Instead of using system Python, we need to use brewed Python (this is basically Python installed using Homebrew). Install Python using Homebrew: This is an important step! Homebrew is a package manager for OS X that makes our lives easier in many different ways.

It’s a dmg file, so you can just download it and run the installer. If you don’t, you can download it from here.

Let’s see how to install OpenCV 3 with Python support on Mac OS X.ĬMake: Make sure you have cmake. Since OpenCV is available on almost all the popular platforms, this version looks very promising. They have greatly improved Python support in this release as well. One of the main additions of OpenCV 3 is “opencv_contrib” which contains a lot of cutting edge algorithms for feature descriptors, text detection, object tracking, shape matching, and so on. OpenCV has been around for a while now and they add something new and interesting with every new release. OpenCV is the world’s most popular computer vision library and it’s used extensively by researchers and developers around the world.
