MOTION PICTURE ENCODING/DECODING APPARATUS, ADAPTIVE DEBLOCKING FILTERING APPARATUS AND FILTERING METHOD FOR SAME, AND RECORDING MEDIUM |
摘要 |
A video encoding/decoding apparatus, an adaptive deblocking filtering apparatus and a filtering method for same, and a recording medium are disclosed. The filtering apparatus includes: a boundary strength determiner for determining strength of boundaries between subblocks of current block; a direction selector for selecting multiple directions preset with reference to the boundary sequentially; a filtering pixel selector for selecting pixels for filtering based on selected directions; a filtering determiner for determining whether to perform the filtering for the selected directions depending on relationships between pixel values of selected pixels; and a filtering unit for filtering the selected pixels in the selected directions depending on the determination of whether to perform filtering to apply 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 byedges in a plurality of diagonal directions.
