Method of removing blocking artifact using quantization information

摘要

In one embodiment, the method includes obtaining quantization information of a first block. The first block includes a pixel to be filtered. The method further includes determining a filtering coefficient based on a value obtained from a table using the quantization information, and obtaining four successive filtered pixel values based on the filtering coefficient. Two of the four successive filtered pixels are included in the first block and two of the four successive filtered pixels are included in a second block adjacent the first block.
