Some more details for the technical minded people: The used algorithm is based on PatchMatch [1], one of the best known in-painting-algorithms (a variant of it is also used in Photoshop). I implemented the algorithm in Renderscript, which gives a massive speed boost over plain Java in Android. It's my first project in Renderscript, it was quite an instructive process, despite the not very abundant documentation and teaching material.
