What's also impressive to me is that Google's solution seems robust, meaning it does a good job in the face of outliers like lens flare, exposure changes, and the like. I see a lot of research with canned results where they optimize for the 6 or so clips they test with, but it's an order of magnitude harder to make it robust enough to release it as GA to the general public.
