Last week I went to Eurographics 2010. I'm not currently working with anything related to advanced graphics research, so I didn't have to consider what information would be useful and could choose sessions completely based on my personal interests.
Alexei Efros keynote was about how data from large online image collections (such as flickr) can be used to do the seemingly impossible task of removing an object from a photograph and replacing it with a plausible background. If you thought Photoshop's new content-aware fill was amazing, wait until you see this. It's close to magic.
Shown in the image: Original image, masked image, candidate replacements and final result. See the paper and presentations.
