I cannot say that it is the "best" library, but I think you can try this: http://algart.net/java/AlgART/ It is an open-source Java library, supporting generalized "smart" arrays and matrices with elements of different types (from 1 bit to 64-bit floating point), including 2D-, 3D- and multidimensional image processing and other algorithms, working with arrays and matrices. Unfortunately right now it consists not enough demo and examples, but, on the other hand, it contains a lot of JavaDocs. It lay in the base of commercial software (SIMAGIS) during several years, but now it is open-source.

对于商业工具，您可能想尝试Snowbound。

我使用它们的经验有些过时，但我发现它们的Java Imaging API比JAI更容易使用，速度也快得多。

他们的客户支持和代码示例也非常好。

另一个不错的选择是马文

加工技术很新，但是非常非常好。

我不懂Java，但OpenCV很适合我的需求。不确定是否适合你的。这是一个Java端口，我认为: http://docs.opencv.org/2.4/doc/tutorials/introduction/desktop_java/java_dev_intro.html
