Abstract
In video encoding and decoding process, provided are method and apparatus for determining whether a slice including an adjacent pixel located at upper-left or lower-right side of current pixel from among adjacent pixels used for adaptive loop filter of current pixel is different from a slice including current pixel, determining a value of adjacent pixel located at upper-left or lower-right side as a value of closest pixel in horizontal direction of adjacent pixel located at the upper-left or lower-right side from among pixels included in the slice including current pixel, determining an adaptive loop filter including a filter coefficient for the current pixel and adjacent pixels based on values of current pixel and adjacent pixels, correcting the value of current pixel by using the values of adjacent pixels, by applying the adaptive loop filter to the current pixel, and encoding/decoding a current block including the current pixel.
