OpenCV is almost a standard in computer vision. It works on both unix like and windows platforms - http://opencv.willowgarage.com/wiki/. Follow the installation manual and the basic tutorials to get started.

There is a processing library that calls OpenCV functions. That way you could use the OpenCV functionality without going down to c++ yourself. You can use the processing library with java without using the whole processing stuff.
