Title: INTRA-PREDICTION MODE-BASED IMAGE PROCESSING METHOD AND APPARATUS THEREFOR
Abstract:
Disclosed are an intra-prediction mode-based image processing method and an apparatus therefor. Particularly, the intra-prediction mode-based image processing method may comprise the steps of: generating a predicted sample of a current block on the basis of an intra-prediction mode of the current block; calculating the distance between the predicted sample and a first reference sample used to generate the predicted sample; and when the distance between the predicted sample and the first reference sample is larger than a filtering reference value, filtering the predicted sample by a weighted addition of the predicted sample and a second reference sample, wherein, among reference samples adjacent to the current block, at least one of a reference sample having the same horizontal coordinate component as the predicted sample and a reference sample having the same vertical coordinate component as the predicted sample is used as the second reference sample.
