Abstract:
A method of removing coding artifacts in first and second processed edges that are processed edges in an image signal and in different directions includes: determining, based on at least pixel values of first adjacent pixels adjacent to the first processed edge, a first target pixel from which coding artifacts are to be removed for the first processed edge (S11); removing coding artifacts from the determined first target pixel (S13); determining, based on at least pixel values of second adjacent pixels adjacent to the second processed edge, a second target pixel from which coding artifacts are to be removed for the second processed edge (S12); and removing coding artifacts from the determined second target pixel (S14), wherein at S12, the second target pixel is determined based on pixel values of the second adjacent pixels from which the coding artifacts are not removed at S13.
