Scene Completion Using Millions of Photographs
 
Spotted this and my jaw dropped:

Quote:
What can you do with a million images? In this paper we present a new image completion algorithm powered by a huge database of photographs gathered from the Web. The algorithm patches up holes in images by finding similar image regions in the database that are not only seamless but also semantically valid. Our chief insight is that while the space of images is effectively infinite, the space of semantically differentiable scenes is actually not that large. For many image completion tasks we are able to find similar scenes which contain image fragments that will convincingly complete the image. Our algorithm is entirely data-driven, requiring no annotations or labelling by the user. Unlike existing image completion methods, our algorithm can generate a diverse set of image completions and we allow users to select among them. We demonstrate the superiority of our algorithm over existing image completion approaches.

Although the example given looks suspiciously like the final photo has had the roofs cut and pasted over the top to produce the first one!

The SigGraph paper (available here) gives more examples as well as comparisons to other algorithms.

I linked to the paper in my first post ;)

Looks good but, surely if you a hardcore photographer (hobbie) it defeats the purpose of what you are aiming to do.

Although I suspect journalists etc might find this very useful in the future
