US 10,567,755 B2 · Method for processing video signal, and apparatus therefor

Abstract

The present invention relates to a method for decoding a video signal, and an apparatus therefor, the method comprising the steps of: obtaining at least one first reference sample from a first reference picture which is different from a picture containing a current block; generating a first reference sample which is filtered by applying a filter to the obtained first reference sample; generating a reference sample array from the difference between the obtained first reference sample and the filtered first reference sample; obtaining first disparity vector information from the video signal; obtaining a first prediction sample from the generated reference sample array on the basis of the first disparity vector information; and restoring the current block on the basis of the first prediction sample.
