Provided are a video decoding method and a video decoding apparatus capable of performing the video decoding method. The video decoding method includes: determining neighboring pixels of a current block to be used for performing intra prediction on the current block; acquiring, from a bitstream, information indicating one of a plurality of filtering methods used on the neighboring pixels; selecting one of the plurality of filtering methods according to the acquired information; filtering the neighboring pixels by using the selected filtering method; and performing the intra prediction on the current block by using the filtered neighboring pixels, wherein the plurality of filtering methods comprise a spatial domain filtering method and a frequency domain filtering method, wherein the spatial domain filtering method filters the neighboring pixels in a spatial domain, and the frequency domain filtering method filters the neighboring pixels in a frequency domain.
