FacePreview using new OpenCV API

[GoogleCodeExporter]

It would be nice to modify the FacePreview example to use the new API of OpenCV 
2.3 as shown here:

sifier.html#cascade-classifier

Unfortunately, I do not have any plans at the moment to support the "new C++ 
API". See here for an explanation:

If you wish to make a contribution though, you are welcome to do it :)

I would like to but I struggle a lot as the documentation of JavaCV is, well, 
non-existing?! Or I haven't found it yet.

What's the best place to ask and discuss questions related to my efforts?
For example, I'm currently wondering why CascadeClassifier.detectMultiScale 
requires the second
argument to be a CvRect instead of a vector or CvSeq (or similar)?

Thanks very much for the great work btw - I've played around with several code 
bases
available on the web for using OpenCV with the integrated camera of my tablet 
and yours works by far best :)

Not much documentation no, but if you are looking into using OpenCV functions, 
simply refer to the OpenCV documentation. It's the same API, more or less.

You should ask questions on the mailing list, if possible, thank you.

JavaCV maps std::vector arguments to more simple Pointer/native arrays objects, 
allocated on return, that's all.
