* cloning.cpp
|

|
||||
* Author:
|
||||
* Siddharth Kherada <siddharthkherada27[at]gmail[dot]com>
|
||||
*
|
||||
* 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
|
||||
* 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.
|
||||
|
||||
* 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.
|
||||
|
||||
* Result: The cloned image will be displayed.
