Abstract
An image processing method includes receiving a bitstream comprising a first encoding unit and a second encoding unit; acquiring from the bitstream a reference value for decoding of the first coding unit, a weight value for performing interpolation using the reference value to determine one or more sample values, and an index indicating one of the one or more sample values; decoding the first encoding unit using the index and a result of interpolation performed using the reference value and the weight value; and decoding the second encoding unit from the bitstream using the interpolation result used in the decoding of the first encoding unit.
Claims27
An image processing method comprising:
- receiving a bitstream comprising a first encoding unit and a second encoding unit;
- acquiring from the bitstream a reference value for decoding of the first coding unit, a weight value for performing interpolation using the reference value to determine one or more sample values, and an index indicating one of the one or more sample values;
- decoding the first encoding unit using the index and a result of interpolation performed using the reference value and the weight value;
- and
- decoding the second encoding unit from the bitstream using the interpolation result used in the decoding of the first encoding unit.
An image processing apparatus comprising:
- a receiver configured to receive a bitstream comprising a first encoding unit and a second encoding unit;
- and
- a decoder configured to:
- acquire from the bitstream a reference value for decoding of the first coding unit, a weight value for performing interpolation using the reference value to determine one or more sample values, and an index indicating one of the one or more sample values;
- decode the first encoding unit using the index and a result of interpolation performed using the reference value and the weight value;
- and
- decode the second encoding unit from the bitstream using the interpolation result used in the decoding of the first encoding unit.
An image processing apparatus comprising:
- a receiver configured to receive a bitstream comprising a first encoding unit and a second encoding unit;
- and
- a decoder configured to:
- acquire from the bitstream first parameters for decoding the first encoding unit;
- decode the first encoding unit by using some of the parameters to obtain an interim decoding result, and using another one of the parameters to obtain a final decoding result;
- and
- decode the second encoding unit using the interim decoding result of the first encoding unit or the final decoding result of the first encoding unit.
