SIMPLIFICATIONS ON DISPARITY VECTOR DERIVATION AND MOTION VECTOR PREDICTION IN 3D VIDEO CODING |
| 摘要 |
A device for coding three-dimensional video data includes a video coder configured to determine a first block of a first texture view is to be coded using a block-based view synthesis mode; locate, in a depth view, a first depth block that corresponds to the first block of the first texture view; determine depth values of two or more corner positions of the first depth block; based on the depth values, derive a disparity vector for the first block; using the disparity vector, locate a first block of a second texture view; and, inter-predict the first block of the first texture view using the first block of the second texture view. |

1. A method of coding three-dimensional (3D) video data, the method comprising:
determining a first block of a first texture view is to be coded using a block-based view synthesis mode; locating, in a depth view, a first depth block that corresponds to the first block of the first texture view; determining depth values of two or more corner positions of the first depth block; based on the depth values, deriving a disparity vector for the first block; using the disparity vector, locating a first block of a second texture view; inter-predicting the first block of the first texture view using the first block of the second texture view. |
