MOTION PICTURE ENCODING/DECODING APPARATUS, ADAPTIVE DEBLOCKING FILTERING APPARATUS AND FILTERING METHOD FOR SAME, AND RECORDING MEDIUM

WIPO Patent Application WO/2010/050699

A3

The present invention relates to a motion picture encoding/decoding apparatus, an adaptive deblocking filtering apparatus and a filtering method for same, and a recording medium. The deblocking filtering apparatus according to one embodiment of the present invention comprises: a boundary intensity determination unit which determines the intensity of the boundary between sub-blocks of the present block; a direction selection unit which sequentially selects directions one by one from among a plurality of directions which are preset on the basis of the boundary; a pixel selection unit which selects pixels to be filtered on the basis of the selected direction; a filtering determination unit which determines whether or not to perform filtering in the selected direction in accordance with the relationship among pixel values of the selected pixels; and a filtering unit which performs filtering on the selected pixels in the selected directions in accordance with the result of the determination of the filtering determination unit. The present invention subjects pixel-wide deblocking filtering in a plurality of directions as well as in vertical and horizontal directions, thus effectively removing block distortions resulting from a diagonal discontinuity caused by edges in a plurality of diagonal directions.
