* cloning_demo.cpp
*
* Author:
* Siddharth Kherada <siddharthkherada27[at]gmail[dot]com>
*
* This tutorial demonstrates how to use OpenCV seamless cloning
* module without GUI.
*
* 1- Normal Cloning
* 2- Mixed Cloning
* 3- Monochrome Transfer
* 4- Color Change
* 5- Illumination change
* 6- Texture Flattening

* The program takes as input a source and a destination image (for 1-3 methods)
* and ouputs the cloned image.
*
* Download test images from opencv_extra folder @github.
