Installing OpenCV for Processing in Eclipse on a Mac

A tutorial on how to install the Open CV library for Processing in Eclipse on OSX.

( After going through the painful process of figuring out how to do this twice, I decided to write up the steps, for personal reference and to hopefully help anyone else out there in this unique predicament. Note: I am running OSX10.6.8 . )

(This presumes you already know how to run a normal processing sketch from eclipse.)

1. Download opencv-framework-1.1.dmg and install it.
2. Download the OpenCV Processing Library and unzip.
3. Copy both OpenCV.jar and libOpenCV.jnilib to /System/Library/Java/Extensions/
4. Now, Locate your Processing’s core.jar and also copy it to /System/Library/Java/Extensions/
5. Ensure that any java project you run, runs in 32-bit mode. Do this by Right-Clicking your Project > Run Configurations > Arguments Tab > VM Arguments: “-d32″ (without the quotes).

Now you’re all set up, you should be able to try out some introductory opencv tutorial.

Update:

Some additional notes:

[4], Processing’s core.jar file can be found (in OSX), by Right Clicking the Processing App > Show Contents > Resources > Java > core.jar.

[5], Right-Click on a Java Project you created in Eclipse, usually found in the left-navigational panel.

Here is a processing_template.
