ABSTRACT:
In the method, a pixel in a first block of an image is filtered according to a filtering methodology, where the filtering methodology includes determining a filtering strength. A filtering strength of one is determined 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.
