GSoC 2011 - (Almost) Final results and thanks!

The end of Google Summer of Code 2011 is near, and I have failed to post enough updates on my blog. But that does not mean one bit that I failed to make progress. I'm proud to present you with my results:


Result, using my GIMP tool :D

My tool allows you to move the paste on the image and see it update according to it's environment, so that it will paste seamlessly. It's not real-time yet, since I recompute some values that should be cached everytime, but most work to enable caching is done, and I hope to reach that before the final deadline. (Even if it won't be before the deadline, I will do it even after GSoC ends).

This is also the time to thanks all the people who made this possible:

• The authors of the Coordinates for Seamless Cloning article, who developed this algorithm.
• Prof. Daniel Cohen-Or, the professor who taught me computer graphics at the university, and helped me understanding the article (he is also one of the article authors).
• My GSoC mentor, Michael Natterer (aka mitch), who agreed to mentor me and assisted me when I was stuck.
• Mason Green, the original author of the poly2tri library, which was heavily used in the project for computing interpolation meshes. I would have never reached the project deadline without his amazing library.
• Prof. Jonathan Richard Shewchuk, who developed some of the geometrical algorithms that were used in this project.
• Finally, special thanks to all the great guys on the GIMP and GEGL irc who helped a lot - mitch, Bat`O, pippin, Alexia_Death, Mikachu, and more.
