Apparatus for removing blocking artifact by filtering pixel in second block using filter coefficient obtained using quantization information for first block
Apparatus for removing blocking artifact by filtering pixel in second block using filter coefficient obtained using quantization information for first block
In one embodiment, the apparatus includes a decoder configured to obtain quantization information of a first block, and determine a filtering coefficient based on values obtained by using the quantization information. A filtered pixel value included in a second block is obtained by the decoder based on the filtering coefficient. The second block is adjacent to the first block.
