1. A video decoding method comprising:
determining whether or not an intra prediction edge filtering is performed;
determining an intra prediction edge filtering region between a vertical edge pixel line and a horizontal edge pixel line based on an intra prediction mode of a current block;
determining filter coefficients applied to prediction pixels in the intra prediction edge filtering region;
filtering the intra prediction edge filtering region based on the filter coefficients to generate an intra prediction block of the current block; and
generating a reconstructed block based on the intra prediction block and a residual block,
wherein the vertical edge pixel line is determined as the intra prediction edge filtering region, if the intra prediction mode of the current block is a first intra prediction mode indicating that each pixel of the current block is predicted from an above-right reference pixel, and
the horizontal edge pixel line is determined as the intra prediction edge filtering region, if the intra prediction mode of the current block is a second intra prediction mode indicating that each pixel of the current block is predicted from a below-left reference pixel.
