How can I write my own python wrapper function for a C++ function, which does the automatic numpy->cv::Mat conversion for its arguments in the same way as the OpenCV python wrappers do?

As near as I can tell, the (generated) OpenCV python wrappers use pyopencv_to and pyopencv_from from modules/python/cv2.cpp. Should I just copy these (with appropriate licensing)? Or is there a library I can link against which provides such helper functions?

Excellent question. I would also like to know how to exploit these facilities.

I too am looking for a library or header file that makes it simple to access OpenCV code written in C++ from Python. In case anyone have an idea on the best way to do it, but not enough time to implement it, I might be able to help.

Something like Boost::Python may be a good place to start, if you're interested.
