The Java Advanced Imaging provides powerful collection of methods for image processing and image analysis for Java.

The Java Advanced Imaging API (JAI) provides a set of object-oriented interfaces that supports a simple, high-level programming model which allows images to be manipulated easily in Java applications and applets. JAI goes beyond the functionality of traditional imaging APIs to provide a high-performance, platform- independent, extensible image processing framework.
