We're excited to present EgoCap – our new egocentric motion-capture capture approach – at SIGGRAPH Asia 2016!

An interesting graph taken from [1], Google's research on what different strategies experts and non-experts take to stay secure online. Biggest difference: experts use unique passwords and password managers, non-experts rely on anti-virus software.

It's interesting to see the effect of a partial solar eclipse that darkens the sun by about 3 quarters at its peak. Taken in Saarbrücken on 20 Mar 2015.

Longest time lapse yet with 5 hours in a minute (×300 speed). Watch out for kids building a snow fort :)

Amazing to see stereo panoramas (aka ‘VR photos’) coming to mobile phones with Cardboard Camera. Can't wait for the iPhone version!

Definitely. I saw a demo for videos at SIGGRAPH, and it was great!

Exciting stuff!
 
Here's our new paper on creating time-lapse videos from Internet photos that will appear in SIGGRAPH 2015!

Project website: 
http://grail.cs.washington.edu/projects/timelapse/

Abstract:
We introduce an approach for synthesizing time-lapse videos of popular landmarks from large community photo collections. The approach is completely automated and leverages the vast quantity of photos available online. First, we cluster 86 million photos into landmarks and popular viewpoints. Then, we sort the photos by date and warp each photo onto a common viewpoint. Finally, we stabilize the appearance of the sequence to compensate for lighting effects and minimize flicker. Our resulting time-lapses show diverse changes in the world's most popular sites, like glaciers shrinking, skyscrapers being constructed, and waterfalls changing course.

My second time lapse is a little more interesting than the first, showing the view outside my window at the MPI. It sums up half an hour in a minute (30× speed).

Thank you )
For that timelapse I have used the diaphragm priority mode of my camera. So, only the exposure time was adjusting to the changing light conditions. But, I still had "flickering" on the 17-th second of the video.
If you shoot timelaps at daytime, the best choice will be to use fully manual mode of a camera, with fixed exposure time (longer then 1/30 sec). It will help to reduce flickering.
Another option to handle the exposure changes is to post-process the timelapse sequence in Lightroom, applying the automatic exposure to all of the images.
The freely licensed music is usually present in the youtube clips. If the used music is not free, youtube usually blocks the clip. I have used the SoundHound App to find out the name of interesting music from another timelapse videos on youtube, and downloaded it from the web. The same trick works with the free radio www.di.fm
