Document Type and Number:

WIPO Patent Application WO/2018/062880

Kind Code:

A1

Abstract:

Disclosed are an image processing method and an apparatus therefor. Specifically, the image processing method comprises the steps of: obtaining an intra prediction mode; obtaining a reference sample using a neighboring sample of the current block; determining whether to perform filtering on the reference sample; filtering the reference sample if it is determined to perform the filtering; and generating a prediction block using the reference sample or the filtered reference sample on the basis of the prediction mode, wherein the current block is a non-square block, the reference sample comprises a left reference sample and a top reference sample, and whether to perform the filtering is determined on the basis of at least one of a current block parameter or a surrounding block parameter.
