1. A video decoding method comprising:
determining an intra prediction edge filtering strength;
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;
filtering the intra prediction edge filtering region based on the intra prediction edge filtering strength to generate an intra prediction block of the current block; and
generating a reconstructed block based on the intra prediction block and a reconstructed residual block corresponding to the current 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.
