Abstract
An image encoding/decoding method and apparatus of the present invention may divide one picture into a plurality of division units, determine whether to perform filtering on a boundary of a current division unit based on a predetermined flag, and perform filtering on the boundary of the current division unit in response to the determination.
Claims13
A method of decoding an image, comprising:
- dividing one picture into a plurality of division units;
- determining whether to perform filtering on a boundary of a current division unit based on a predetermined flag;
- and
- performing filtering on the boundary of the current division unit in response to the determination,
- wherein the division unit includes at least one of a sub picture, a slice, or a tile,
- wherein the flag includes at least one of a first flag indicating whether filtering is performed on a boundary of a division unit within the one picture or a second flag indicating whether filtering is performed on the boundary of the current division unit in the one picture,
- wherein whether to perform filtering on the boundary of the current division unit is determined by further considering a third flag indicating whether filtering is performed on a boundary of a neighboring division unit adjacent to the current block unit.

A non-transitory computer-readable storage medium storing instructions that, when executed, cause a processor to:
- divide a picture into a plurality of division units;
- determine whether to perform filtering on a boundary of a current division unit based on a predetermined flag;
- and
- perform filtering on the boundary of the current division unit in response to the determination,
- wherein the division unit comprises at least one of a sub picture, a slice, or a tile,
- wherein the flag comprises at least one of a first flag indicating whether filtering is performed on a boundary of a division unit within the one picture or a second flag indicating whether filtering is performed on the boundary of the current division unit in the one picture,
- wherein whether to perform filtering on the boundary of the current division unit is determined by further considering a third flag indicating whether filtering is performed on a boundary of a neighboring division unit adjacent to the current block unit.
