Abstract
In one embodiment, a pixel in a block of the image is filtered according to a filtering methodology. The filtering methodology includes determining a filtering strength value. This determining step determines a first filter strength value if the block has non-zero transform coefficient information and determines a second filter strength value if a motion vector difference between a motion vector of the first block and a motion vector of an adjacent second block is greater than or equal to one. The first filter strength value is greater than the second filter strength value.
Claims2
A filtering method of a block boundary region in a loop filtering system, the method comprising:
- determining a filtering strength with respect to the block boundary region;
- and
- filtering the block boundary region based on the determined filtering strength,
- wherein, in the filtering strength determining step, the filtering strength is determined as a first strength based on whether blocks corresponding to a block boundary include non-zero transform coefficient information, or the filtering strength is determined as a second strength based on motion vector information of blocks corresponding to of the block boundary region.
