Abstract
An image processing method based on an intra-prediction mode and an apparatus for the same. Particularly, the method may include deriving an intra-prediction mode of a current block, constructing a reference sample to be used for a prediction of the current block from a neighboring sample of the current block, generating a prediction block of the current block based on the intra-prediction mode by using the reference sample, and performing a post filtering by using an adjacent sample of the prediction sample for each prediction sample in the prediction block.
