One of the things I did during my stint at Sony was video stabilization for their desktop nonlinear video editing software. We were hoping to not only stabilize (which is a pretty straightforward thing to do these days) but also use the motion data to inform a deconvolution to clean up motion blurred frames. Alas, my project ran out of time and we ended up licensing a third party stabilizer.

But yes, most image processing techniques like this lend themselves to video. This is something I hope my startup will someday be able to integrate into our collaborative video editor...
