Īlso, make sure you have ant installed in your system, if not, install it with HomeBrew as well.Īfter modifying the brew command, and installing ant, you can effectively install OpenCV: brew install -build-from-source opencv To install OpenCV (with Java support) through Homebrew, you need to edit the opencv formula in Homebrew, to add support for Java: brew edit opencv In the text editor that will open, change the line: -DBUILD_opencv_java=OFF to -DBUILD_opencv_java=ON. There’s a great site by Adrian Rosebrock where you can find tons of cool examples of different applications of OpenCV, as well as installation instructions.įor this specific scenario, as we are just focusing on Java, we’ll follow the simple instructions from the following site ( ), to modify HomeBrew formula for OpenCV, and install it will Java compatibility. We are not particularly interested in those features (for now), but we’ll just get the latest version so we don’t need to struggle in the future with updates. OpenCV 4 was released on late 2018, and provides some new features mainly related to deep learning.

If this is the case, check my previous article on getting HomeBrew installed on your system.Īfter getting HomeBrew installed, our next step on this journey is to get the latest version of OpenCV. If you landed here, you are probably working on a Mac based system, and looking forward to work with OpenCV. I’ve worked with OpenCV version 3 on Windows and Ubuntu in the past, and did a single install in OSx a couple of years ago.
