Abstract
Disclosed is an in-loop filtering method according to an adaptive pixel classification standard. The in-loop filtering method according to an adaptive pixel classification standard in a video decoding apparatus comprises the steps of: classifying reconstructed samples according to an absolute 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, errors in the reconstructed image can be corrected.
Claims3
A method of performing in-loop filtering on the basis of an adaptive pixel classification standard, wherein the method is performed in an image decoding apparatus, the method comprising:
- classifying a reconstructed sample according to an absolute classification standard or relative classification standard;
- obtaining offset information on the basis of the result of which the reconstructed sample is classified;
- adding an offset value to the reconstructed sample by referring to the obtained offset information;
- and
- outputting the reconstructed sample to which the offset value is added.
