Abstract: An image decoding method can be performed by an image decoding apparatus. The image decoding method can include obtaining image information including prediction mode information for a current block, deriving a prediction mode of the current block based on the prediction mode information, deriving reference samples neighboring the current block, deriving prediction samples of the current block based on the prediction mode of the current block and the reference samples, and generating reconstructed samples of the current block based on the prediction samples. The reference samples include top reference samples of the current block and left reference samples of the current block. Further, whether a filtering is applied to the reference samples is determined based on the prediction mode of the current block and a size of the current block.
