Abstract
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.
