My oral presentation about the "Completeness of Coding with Image Features" at the British Machine Vision Conference 2009 in London has been recorded on video. It is now available at videolectures.net. If you're interested in the work, read the full paper.

I highly recommend listening to Alyosha Efros's invited talk, "What can the world tell us about an image?", and Andrew Fitzgibbon's motivating two-hour Tutorial on continuous optimization, covering parts of Triggs' excellent survey of bundle adjustment techniques.
