    • This disclosure describes techniques for coding 3D video block units. In one example, a video encoder is configured to receive one or more texture components from at least a portion of an image representing a view of three dimensional video data, receive a depth map component for at least the portion of the image, code a block unit indicative of pixels of the one or more texture components for a portion of the image and the depth map component. The coding comprises receiving texture data for a temporal instance of a view of video data, receiving depth data corresponding to the texture data for the temporal instance of the view of video data, and encapsulating the texture data and the depth data in a view component for the temporal instance of the view, such that the texture data and the depth data are encapsulated within a common bitstream.

    • This disclosure describes techniques for estimating a depth of image objects for a two-dimensional (2D) view of a video presentation. For example, an initial indication of depth (e.g., an optical flow) may be determined for a 2D view. The initial indication of depth may be used to estimate global motion, e.g., motion of an observer (e.g., camera), of the 2D view. The initial indication of depth may be modified based on the estimation of global motion to create a global motion-adjusted indication of depth. The global motion-adjusted depth indication may be used to create a depth map for the 2D view, which may be used to generate an alternative view of the video presentation that may be used to display a three-dimensional (3D) video presentation.
    • 本公开描述了用于估计视频呈现的二维(2D)视图的图像对象的深度的技术。 例如,可以为2D视图确定深度的初始指示(例如,光流)。 深度的初始指示可以用于估计2D视图的全局运动,例如观察者(例如,相机)的运动。 可以基于全局运动的估计来修改深度的初始指示,以创建全局运动调整的深度指示。 全局运动调整深度指示可用于为2D视图创建深度图,其可以用于生成可用于显示三维(3D)视频呈现的视频呈现的替代视图。

    • This disclosure describes techniques for estimating a depth of image objects for a two-dimensional (2D) view of a video presentation. For example, a plurality of feature points may be determined for a 2D view. The plurality of feature points may be used to estimate global motion, e.g., motion of an observer (e.g., camera), of the 2D view. For example, the plurality of feature points may be used to generate a global motion frame difference. The global motion frame difference may be used to create a depth map for the 2D view, which may be used to generate an alternative view of the video presentation that may be used to display a three-dimensional (3D) video presentation.
