- 7. Configuring Eclipse we willdefine OpenCV as a user library in Eclipse, so we can reuse the configuration for any project. Launch Eclipse and select Window –> Preferences from the menu.
- 8. Configuring Eclipse Navigate underJava –> Build Path –> User Libraries and click New....
- 9. Configuring Eclipse Enter aname, e.g. OpenCV-3.0.0, for your new library.
- 10. Configuring Eclipse Now selectyour new user library and click Add External JARs....
- 11. Configuring Eclipse Browse throughC:opencvbuildjava and select opencv-246.jar. After adding the jar, extend the opencv-300.jar and select Native library location and press Edit....
- 12. Configuring Eclipse After addingthe jar, extend the opencv-300.jar and select Native library location and press Edit....
- 13. Configuring Eclipse Select ExternalFolder... and browse to select the folder C:OpenCV- 2.4.6buildjavax64. If you have a 32-bit system you need to select the x86 folder instead of x64.
- 14. Configuring Eclipse Your userlibrary configuration should look like this: Done ☺
- 15. Testing the configurationon a new Java project Now start creating a new Java project.
- 16. Testing the configurationon a new Java project Write the Project name
- 17. Testing the configurationon a new Java project On the Java Settings step, under Libraries tab, select Add Library->User Library... and select OpenCV-3.0.0, then click Finish.
- 18. Testing the configurationon a new Java project Libraries should look like this:
- 19. Testing the configurationon a new Java project Now you have created and configured a new Java project it is time to test it. Create a new java file.
- 20. Testing the configurationon a new Java project Here is a starter code for your convenience:
- 21. Testing the configurationon a new Java project When you run the code you should see 3x3 identity matrix as output. That is it, whenever you start a new project just add the OpenCV user library that you have defined to your project and you are good to go. Enjoy your powerful, less painful development environment :) Updated version of http://docs.opencv.org/2.4/doc/tutorial s/introduction/java_eclipse/java_eclipse .html#java-eclipse Author: Barış Evrim Demiröz A tutorial on how to use OpenCV Java with Eclipse.
