Matlab implementation of Possion image editing.
Gradient domain is used instead of intensity of pixels in image cloning to blend two images by solving Poisson equations with a predefined boundary condition. Based on this idea, this presents two options:
1- seamless cloning
2- mixing gradients
For more information read Readme.pdf

Instructions:
1- Open Demo.m
2-change the filenames as you want:
source='source_image.jpg';
target='target_image.jpg';
result='result_image.jpg';
3-Run Demo.m

This is an implementation of the following paper:
Pérez, Patrick, Michel Gangnet, and Andrew Blake. "Poisson image editing." ACM Transactions on Graphics (TOG). Vol. 22. No. 3. ACM, 2003.
