There was a very interesting plenary talk at ICRA 2009 about "Computational Cameras" given by Prof. Shree Nayar of Columbia University.  A video of the plenary is included below, as well as a discussion of some of its contents -- from assorted pixel techniques for high dynamic range to flexible depth of field photography -- all very cool stuff!  These developments are particularly relevant to robotics, as cameras are probably the most ubiquitous sensors encountered.  This video was made available in the ICRA 2009 podcasts.  While there is a large push for open-access journals / conferences, freely-available recordings of conference talks is even more lacking.  As I find these more entertaining than television, I really hope this becomes a common trend (perhaps the RSS committee members are watching...?).
