Abstract
In one embodiment, the apparatus includes a decoder configured to obtain a pixel value difference between two successive pixels. The two successive pixels are on a block boundary. The decoder is configured to calculate the filtering coefficient based on the pixel value difference, weight the filtering coefficient, and obtain a filtered pixel value based on the weighted filtering coefficient.
