Abstract
Techniques are described determining a partition pattern for intra-prediction encoding or decoding a depth block from a partition pattern of one or more partition patterns associated with smaller sized blocks. A video encoder may intra-prediction encode the depth block based on the determined partition pattern, and a video decoder may intra-prediction decode the depth block based on the determine partition pattern.
Claims27
A method of decoding video data, the method comprising:
- determining a partition pattern associated with a block of a first size;
- determining a partition pattern for a depth block of a second size based on the determined partition pattern associated with the block of the first size, wherein the second size is larger than the first size;
- and
- intra-prediction decoding the depth block based on the determined partition pattern for the depth block.
A method of encoding video data, the method comprising:
- determining a partition pattern associated with a block of a first size;
- determining a partition pattern for a depth block of a second size based on the determined partition pattern associated with the block of the first size, wherein the second size is larger than the first size;
- and
- intra-prediction encoding the depth block based on the determined partition pattern for the depth block.
A device for video coding, the device comprising:
- a video data memory that stores one or more partition patterns associated with a block of a first size;
- and
- a video coder comprising one or more processors, the video coder configured to:
- determine a partition pattern associated with the block of the first size from the stored one or more partition patterns;
- determine a partition pattern for a depth block of a second size based on the determined partition pattern associated the block of the first size, wherein the second size is larger than the first size;
- and
- intra-prediction code the depth block based on the determined partition pattern for the depth block.
A computer-readable storage medium having instructions stored thereon that when executed by one or more processors of a device for video coding cause the one or more processors to:
- determine a partition pattern associated with a block of a first size;
- determine a partition pattern for a depth block of a second size based on the determined partition pattern associated with the block of the first size, wherein the second size is larger than the first size;
- and
- intra-prediction code the depth block based on the determined partition pattern for the depth block.
