Those were nearly the exact set of observations we made while using Java this year, before switching to C++. Basically, the Java WPILib does not expose any nivision.h (imaq*) functions, and consequently makes it very difficult to do any effective image processing in Java. One of the options we could have taken was to generate Java wrappers for all those functions, but since I don't know Java that well and it would have been a pain to expose everything, we decided to switch to C++.

If you know C++, I would recommend switching if image processing is one of your requirements.
