Abstract
Provided is an image decoding method including determining at least one first processing mode for decoding of a current block, based on a motion vector resolution (MVR) of the current block, the at least one first processing mode being from among a plurality of processing modes included in at least one of a prediction process, a transform process, and a filtering process; and decoding the current block, according to the at least one first processing mode.
Claims15
An image decoding method comprising:
- determining at least one first processing mode for decoding of a current block, based on a motion vector resolution (MVR) of the current block, the at least one first processing mode being from among a plurality of processing modes comprised in at least one of a prediction process, a transform process, and a filtering process;
- and
- decoding the current block, according to the at least one first processing mode.
An image decoding method comprising:
- determining, based on a motion vector resolution (MVR) of a current block, whether information about at least one first processing mode is comprised in a bitstream, the at least one first processing mode being from among a plurality of processing modes comprised in at least one of a prediction process, a transform process, and a filtering process that are for decoding of the current block;
- and
- decoding the current block, according to the at least one first processing mode, when the information about the at least one first processing mode is comprised in the bitstream.
An image decoding apparatus comprising:
- a decoder configured to determine at least one first processing mode for decoding of a current block, based on a motion vector resolution (MVR) of the current block, the at least one first processing mode being from among a plurality of processing modes comprised in at least one of a prediction process, a transform process, and a filtering process;
- and
- a bitstream obtainer configured to obtain, from a bitstream, information about the at least one first processing mode,
