1. An intra-prediction based video decoding method, comprising:
decoding, from a bitstream, transform coefficients corresponding to a current block to be decoded in a current picture;
configuring an input data using at least one reference area that is included in the current picture and has been decoded prior to the current block, wherein the input data is configured using average pixel values which are generated by performing an averaging operation on values of pixels in the reference area;
filtering the input data using a filter coefficient set which is in a two or three dimensional matrix form; and
predicting the current block based on the filtered input data,
wherein the method further comprises decoding, from the bitstream, first information for selecting the filter coefficient set to apply to the current block among a plurality of filter coefficient sets each of which is in the two or three dimensional matrix form, and
wherein the filtering is performed using the filter coefficient set determined based on the first information.
