YouTube is opening up their 3D services, all 1080p videos are automatically converted in to 3D. The videos are converted when they are uploaded. YouTube users can click on “Gear” icon in the player to view 3D videos. Of course users will have to wear 3D glass to view the 3D videos.

[box_dark]To give you more dimension on 3D, here’s some background how the conversion technology works at YouTube. Since last September we’ve been constantly improving the underlying technology, which now uses several techniques:

We use a combination of video characteristics such as color, spatial layout and motion to estimate a depth map for each frame of a monoscopic video sequence. We use machine learning from the growing number of true 3D videos on YouTube to learn video depth characteristics and apply them in depth estimation. The generated depth map and the original monoscopic frame create a stereo 3D left-right pair, that a stereo display system needs to display a video as 3D[/box_dark]
