I have been wondering how such algorithms work for a long time, and now knowing how it works I can recall that some of the artifacts this algorithm produces are actually quite intuitive. Sometimes for complicated scenes, photoshop or whatever software that does this will simply duplicate a partial region of the image and paste it to the missing area. This might be because there's only very few matching scenes for the edges to expand on and therefore it simply duplicates the whole region part by part.

This is an amazing result, but then I noticed the stones generated by the algorithm are much darker than the adjacent stones. I wonder why this is. It seems like the algorithm could have started generating stones in a shaded region then not have bothered blending them? It seems like texture-synthesis works best when the lighting in a scene is constant and struggles in scenes with shadows / gradients / lighting differences.
