Microsoft engineers have developed Hperlapse, a new way to transform shaky video footage from a GoPro or Google Glass into amazing video footage.
Normally videos taken from a GoPro camera or Google Glass are shaky enough to make you sick, but with this newly developed Hyperlapse technology, the video is smoothed out.
The results are amazing:
SO COOL!
Here’s the method behind the magic:
From the Microsoft research page:
“At high speed-up rates, simple frame sub-sampling coupled with existing video stabilization methods does not work, because the erratic camera shake present in first-person videos is amplified by the speed-up.
Our algorithm first reconstructs the 3D input camera path as well as dense, per-frame proxy geometries. We then optimize a novel camera path for the output video that is smooth and passes near the input cameras while ensuring that the virtual camera looks in directions that can be rendered well from the input.
Next, we compute geometric proxies for each input frame. These allow us to render the frames from the novel viewpoints on the optimized path. Finally, we generate the novel smoothed, time-lapse video by rendering, stitching, and blending appropriately selected source frames for each output frame.”
Like I said…SO COOL! 😀
I am excited to see this technology in the hands of the general public and creatives.
Speak your mind...
