20120257673 | METHOD OF REMOVING A BLOCKING PHENOMENON USING PROPERTIES OF TWO BLOCKS - In one embodiment, the method includes obtaining a coded block pattern of first and second blocks. The coded block pattern may be one of a plurality of coded block patterns, the plurality of coded block patterns may include an intra-coded block, and the second block may be adjacent to the first block. Whether the first block and the second block have non-zero transform coefficient information is determined if the block type of the first block and the second block is not intra-coded block. A non-zero filter strength value is determined based on the obtained coded block pattern of the first and second block and the determination of whether the first block and second blocks have non-zero transform coefficient information, and the blocking phenomenon is removed according to the filter strength value. | 10-11-2012 |
20130202032 | METHOD OF REMOVING A BLOCKING ARTIFACT USING QUANTIZATION INFORMATION IN A FILTERING SYSTEM - In one embodiment, the method includes obtaining quantization information related to at least one of a first block and an adjacent second block, comparing the quantization information with a predefined constant value, and performing a filtering process based on a result from the comparing step. The filtering process includes calculating a value of at least one pixel in the first block to obtain a filtered value based on pixel values of at least two pixels in the first block. The method further includes filtering at least two successive pixels on a block boundary between the first and second blocks. | 08-08-2013 |

20130208815 | METHOD OF REMOVING A BLOCKING ARTIFACT USING QUANTIZATION INFORMATION IN A FILTERING SYSTEM - In one embodiment, the method includes obtaining quantization information related to at least one of a first block and a second block. The second block is adjacent to the first block. The quantization information is compared with a predefined constant value, and block type information for the first and second block is obtained. The block type information indicates whether a block is an intra-coded block. A filtering process is performed based on the comparing step when both of the first block and the second block are intra-coded blocks according to the block type information. The filtering process includes calculating a value of at least one pixel in the first block based on pixel values of at least two pixels in the first block, and calculating a value of at least one pixel in the second | 08-15-2013 |
