Embodiment Construction

[0021] In general, the techniques of this disclosure relate to three-dimensional (3D) video coding. That is, video data coded using these techniques can be rendered and displayed to produce a three-dimensional effect. For example, two images of different views (that is, corresponding to two camera perspectives with slightly different horizontal positions) may be displayed substantially simultaneously such that one image is seen by the viewer's left eye and the other image is viewed by the viewer's left eye. The observer's right eye sees.

[0022] The 3D effect can be achieved using, for example, a stereoscopic display or an autostereoscopic display. A stereoscopic display can be used in conjunction with goggles that filter the two images accordingly. For example, passive glasses may use polarized lenses or different tinted lenses to filter the image to ensure the correct eye sees the correct image. As another example, active glasses may rapidly shade alternating lenses in c...

Abstract

In an example, a method of coding video data includes determining a first depth value of a depth look up table (DLT), where the first depth value is associated with a first pixel of the video data. The method also includes determining a second depth value of the DLT, where the second depth value is associated with a second pixel of the video data. The method also includes coding the DLT including coding the second depth value relative to the first depth value.
