I make a lot of 4K hyperlapse movies, it is tedious as AfterEffect's warp stabilizer is useful only in a small fraction of cases, Deshaker is more consistent but also not perfect, and the only option in the end is multi-pass manual tracking and stabilizing which is very time consuming and tricky for long panning shots.
Very nice! Is there software available I can use, or do I have to implement the algorithms from the paper myself?

A GoPro timelapse is also called a prolapse.

If I were them I would offer this as a web service: upload your video and have it converted for $1.
Someone above mentioned the processing took weeks. So.. I'm not sure that would work.

> recreating a 3d view using multiple photos from different angles I've been waiting for that for years. Searched for it a few months ago, still nothing.
Er, http://photosynth.net/
They may not be killer apps but it is one way for Microsoft to distinguish itself from Apple and Google.

Back of the envelope, i get 7680 frames to process, one minute each which is just under $1300 for a medium windows azure instance. Not cheap, but probably doable. I'd bet you could spend a few hours fiddling with large memory instances versus medium, and find a sweet spot. Set aside $50-100 a month, it'll probably be a lot cheaper in a year. (assuming optimizations and cheaper cloud services)
Or you could just buy a computer and stick it in a corner running 24-7. After it has finished selecting/rendering, you have both a video and a computer you can use afterwards.
As others have commented, the videos look great, and much closer to how people remember journeys. However, there appear to be some image persistence problems (many street poles simply dissolve as they get closer to the camera). I'm curious to see what happens if they insert more action-packed footage. An MTB course with trees, switchbacks, and jumps would be an interesting stress test of this technique.

You think a week of post end processing? I didn't read the paper or anything so I could be way off base, but I would assume the algo simply has to choose which frames to keep and which to toss. I doubt this would take an enormous amount of time even with HD videos. The algo is most likely just really clever in how it chooses a good frame vs a bad one. On the other hand, if it is actually generating a lot of "best gue…
The paper says it took 23,700 minutes to do just the frame selection for the 13 minute bike input video. That's over two weeks.
