1. An image decoding method comprising:
obtaining first information specifying whether intra filtering is applied to a current block;
obtaining second information based on the first information specifying that the intra filtering is applied to the current block; and
determining an intra filter used for intra prediction of the current block based on the second information,
wherein prediction samples of the current block are generated by applying the determined intra filter to neighboring samples of the current block.
