## MatToNDArrayConverter.cpp
/*
 *  This example code is made for describe how to convert OpenCV's Mat class to Boost Numpy's ndarray class and vice versa.
 *  As far as I know, there was some library or boilerplate code about converting Mat to ndarray. But to me those methods were too expensive and difficult to understand.
 *  Recently, I have found that Boost Python has Numpy extension and it gives ndarray class properly.
 *  No other modules are used for conversion, only Boost Python, Boost Numpy, and OpenCV. (Version : Windows7, Python3.5, BoostPython 1.68, OpenCV 4.0.0)
 *  This code is designed to show you a specific case like converting 'CV_8UC3' type Mat image to 'uint8' dtype ndarray. And it contains a minimum of code to explain.
 *  I hope you get the idea of converting ndarray to fit your case properly through this example.
