Abstract
The in-loop filtering method performed by a video decoding apparatus includes: classifying reconstructed samples according to an absolute classification standard or relative classification standard; acquiring offset data on the basis of results of classifying the reconstructed samples; adding an offset value to the reconstructed samples by referencing the acquired offset data; and outputting the offset value-added reconstructed samples. Accordingly, W errors in the reconstructed image can be corrected.
