Abstract
A method for coding a coding unit that is coded with a single sample value is provided. The method selects a coding pattern from at least two predetermined coding patterns, each of which includes a plurality of boundary neighboring samples of the coding unit that have been reconstructed, and decodes the coding unit according to a value of at least one of the plurality of boundary neighboring samples of the selected coding pattern that is available.
Claims20
A method comprising:
- selecting, by a processing system, a coding pattern from a plurality of coding patterns for decoding a coding unit that has been coded with a single sample value, each of the plurality of coding patterns being predetermined to indicate one or more reference samples from which a reference sample can be selected for coding the coding unit, and each of the one or more reference samples being located in a predetermined position in a neighboring coding unit of the coding unit, wherein each of the one or more reference samples is a boundary neighboring sample in a corresponding neighboring coding unit and has been reconstructed;
- and
- decoding, by the processing system, the coding unit according to a value of a first reference sample indicated by the selected coding pattern.
An apparatus comprising:
- a non-transitory memory storage comprising instructions;
- and
- one or more processors in communication with the memory storage, wherein the one or more processors execute the instructions to:
- select a coding pattern from a plurality of coding patterns for decoding a coding unit that has been coded with a single sample value, each of the plurality of coding patterns being predetermined to indicate one or more reference samples from which a reference sample can be selected for coding the coding unit, and each of the one or more reference samples being located in a predetermined position in a neighboring coding unit of the coding unit, wherein each of the one or more reference samples is a boundary neighboring sample in a corresponding neighboring coding unit and has been reconstructed;
- and
- decode the coding unit according to a value of a first reference sample indicated by the selected coding pattern.
