As a result, lipase code is no longer using ijopencv.
ijopencv, based on javacpp provides poor compatibility with
opencv's cpython bindings, not to mention it's much less
convenient. Therefore, I'm not sure that I'll use ijopencv at all...
Due to the lack of documentation, I had to do a lot of tests to find out
how to use opencv in jython, as the interface is not the same as in
python...
In the end, I managed to work out a set of arguments that deosn't cause
an exception.
