| Today we are watching 3D movies in the cinema or in the living room of our home with TVs that support 3D format. In the September of the last year, YouTube offered users a beta version to transform videos from 2D to 3D in a simple manner. after several months, YouTube had extended this functionality to all users to view short-form videos uploaded in 1080p. How it Works? Lets see some background how the conversion technology works at YouTube for providing videos on 3D. YouTube uses 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 YouTube uses 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 Logically, this conversion is an artificial processing that take place during filming videos. Therefore, the transformation responds may be not a perfect one You can select 3D viewing for any YouTube videos in the Quality settings (click on the gear icon) on the YouTube player. |
