Go to LibrariesTab, and then click " Add Library”。 Step by step File > New > Other > Java ProjectCreate a new Java project under, and when finished, right-click the project to configure the build path. Now, click "OK" and we have added OpenCV as a user library. In opencv-2.4.7/build/libGiven under the folder Library directory (lib)route of. Select Native library location,then click" Edit”。 Name this library OpenCV-2.4.7Name, and then click "OK".Ĭlick on Add External Jars, Then add OpenCV-2.4.7File. Open Eclipse IDE, then go to the project workspace and go to the directory Windows > Preferences > Java > Build Path > User LibrariesNext, choose to add a new library. Under Windows, where you unzip it, there will be an eclipse folder, so you can operate directly, of course, you can also create a shortcut to the executable file to the desktop. If you are on a Linux or Mac machine, open a command line window and enter the following command: $ tar -xzvf eclipse-jee-kepler-R-*.tar.gz The installation of Eclipse is easy, just unzip the downloaded package.

For now, the code name of the latest version of eclipse is Kepler. If eclipse is not installed in your system, you can go Eclipse official websiteDownload the latest version. The above command will be opencv-2.4.7/build/binCreated under the directory opencv-247.jarFile, this is the installation method of Java binding to local OpenCV. In order to build the OpenCV jar, execute the following command: $ cd opencv-2.4.7$ mkdir build$ cd build/$ cmake -G "Unix Makefiles" -D CMAKE_CXX_COMPILER=/usr/bin/g++ -D CMAKE_C_COMPILER=/usr/bin/gcc -D WITH_CUDA=ON .

It is an OpenCV package (including jar file) for Windows users, but not for Linux and Mac OS users. The Java tutorial in the document assumes that the OpenCV jar file is in the generated folder.
#Opencv for mac eclipse how to
I spent a lot of time to understand how to obtain OpenCV jar files. Switch directory to opencv-2.4.7： $ cd opencv-2.4.7
Start learning OpenCV, the first step is to go to it Official websiteDownload the latest version of OpenCV package that supports your current operating system, version 2.4.7 is used in this article.Īfter downloading the package, use the tar command to decompress: $ tar xvf opencv-2.4.7.tar.gz The code for today's demo application is on GitHub: day12-face-detection 。 It provides C++, C, Python and Java interfaces, and supports all mainstream operating system platforms, including Windows, Linux, Mac OS, iOS and Android. It is written in C/C++ and aims to take advantage of multi-core. OpenCV(Open Source Computer Vision)It is an open source computer vision algorithm library. However, I haven't been able to find a complete beginner's tutorial on using OpenCV library through Java, so this article may be a material for others to learn in this regard. After doing some research, I found that OpenCV library can help me detect faces in images.
Face detection helps to recognize faces on any digital image. Today I am going to learn how to use Java for face detection.
