You could check out javacvPro.

That looks like a great library but I'm still getting errors.   I dont think its seeing openCV...

Does anyone know how to install 2.4.2 and where???

I read it needed to be in the C: root directory but nothing is working.

Is there a way to test to see that it installed and is functional?

When I run a sample program for javacvPro I get an error:

Highlighted line of code:
    opencv = new OpenCV(this); // initialise objet OpenCV à partir du parent This

Error message:

Exception in thread "Animation Thread" java.lang.UnsatisfiedLinkError: C:\Users\fxmech\AppData\Local\Temp\jniopencv_core8658060764231121267.dll: Can't find dependent librariesException in thread "Animation Thread" java.lang.UnsatisfiedLinkError: C:\Users\fxmech\AppData\Local\Temp\jniopencv_core8658060764231121267.dll: Can't find dependent libraries


Is it that its looking in the wrong folder fir the files openCV is in C://opencv

For your Problem above:

Download the 32 bit Processing on your 64 bit System. Everything works fine.

For the rectangle thing you need to import this:

1. import java.awt.Rectangle;

cheers

You can install regular JavaCV (OpenCV port for Java) which is much better than javacvpro. You can install it easily in a windows machine. It's running on my machine (Windows 8 64Bits).
