There is an Introduction to Java in the tutorials that will guide you in not only a basic understanding, but even as far as creating a functioning face detection application as an example of OpenCV's capabilities;

http://docs.opencv.org/doc/tutorials/introduction/desktop_java/java_dev_intro.html?highlight=java

There is a more detailed introduction if you want to use Eclipse;

http://docs.opencv.org/doc/tutorials/introduction/java_eclipse/java_eclipse.html?highlight=java

And then there is the Java API Reference that provides the JavaDoc;

http://docs.opencv.org/java/

Not every single feature of OpenCV is found in Java yet, but the list is constantly growing, and the amount of features available already is truly staggering.

When you download and install OpenCV, you'll find Java sample programs under the Samples directory.

Hi,

there's one book coming from PacktPub as well, probably in a couple months.

Kind regards, Daniel

You have to be aware that opencv Android is older than the pure Java version, so there are more samples for Android and the syntax is exactly the same. The differences are on where your images/video come from and where they go to.

As you can imagine Android has API regarding dealing with the camera, while a desktop will have multiple ways to do that.

Besides the samples contained inside the opencv Android package, you can find some more samples here:

These are full eclipse projects which depend from Opencv 2.4.8 (not tested with other versions). They follow the same structure as Android Tutorial 1.
