ENCODING/DECODING APPARATUS AND METHOD USING FLEXIBLE DEBLOCKING FILTERING |
摘要 |
A video decoding method performed by a video decoding apparatus includes: generating a quantized frequency transform block by decoding a bitstream; reconstructing a residual block by inversely quantizing and inversely transforming the quantized frequency transform block; generating a prediction block corresponding to a current block; reconstructing the current block by adding the generated prediction block to the reconstructed residual block; and performing a deblocking filtering with respect to a boundary between subblocks within a frame including the reconstructed current block, by allowing numbers of filtered pixels in a first block of the subblocks and a second block of the subblocks that engage in the filtering to be different depending on one or more predetermined criterion. |

generating a quantized frequency transform block by decoding a bitstream; reconstructing a residual block by inversely quantizing and inversely transforming the quantized frequency transform block; generating a prediction block corresponding to a current block; reconstructing the current block by adding the generated prediction block to the reconstructed residual block; and performing a deblocking filtering with respect to a boundary between subblocks within a frame including the reconstructed current block, by allowing numbers of filtered pixels in a first block of the subblocks and a second block of the subblocks that engage in the filtering to be different depending on one or more predetermined criterion. |
