*
* This tutorial demonstrates how to use OpenCV seamless cloning
* module .
* Flags :
* 1 - NORMAL_CLONE
* 2 - MIXED_CLONE
* 3 - FEATURE_EXCHANGE
* The program takes as input a source and a destination image
*
* 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 .
* - > To reset the region selected , click the middle 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 .
* - > 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 .
