Seamless copy-and-paste of images with Poisson Blending.
An implementation of Poisson Blending, that demonstrates the concepts explained in my article.
To use the progam, you specify a source image and a target image. The source image is seamlessly copied and pasted
into the target image, at some specified pixel location.
By running the command line
poisson_blend -source img/kitten.png -target img/library.png -mask img/kittenmask.png -output result.png -mx 280 -my 340
An image of a kitten can be seamlessly copied and pasted into the library, at the position (280, 340), as can be seen below.
The mask specifies which pixels of the kitten should actually be copied and pasted. The remaining pixels are ignored.
Note that only pure red pixels of RGB color (255,0,0) are considered part of the mask.
The result of the above command line can be seen below:
 |  | <img src=”img/kittenmask.png” alt=”kitten mask” width=”37” height=46”> |  |
| source | target | mask | result |
A small gallery of images made with this program are presented below.

The only dependencies are lodepng and Eigen.
Both of which are included within this repository.
We use CMake for building. If on Linux or OS X, you can build it in the terminal by doing something like:
mkdir build && cd build && cmake .. && make
If on Windows, create a build/ folder, and run cmake .. from
inside that folder. This will create a visual studio solution(if you
have visual studio). Launch that solution, and then simply compile the
project named poisson_blend.
Below we list the soures of all images that we used in the gallery.
