/*
* cloning.cpp
*
* Author:
* Siddharth Kherada <siddharthkherada27[at]gmail[dot]com>
*
* This tutorial demonstrates how to use OpenCV seamless cloning
* module.
*
* 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.
* Step 1:
* -> In the source image, select the region of interest by left click mouse button. A Polygon ROI will be created by left clicking mouse button.
* -> To set the Polygon ROI, click the right mouse button or 'd' key.
* -> To reset the region selected, click the middle mouse button or 'r' key.
* Step 2:
* -> In the destination image, select the point where you want to place the ROI in the image by left clicking mouse button.
* -> To get the cloned result, click the right mouse button or 'c' key.
* -> To quit the program, use 'q' key.
*
* Result: The cloned image will be displayed.
