FIELD: image data processing.
SUBSTANCE: invention relates to the field of computing technology for image processing. The technical result is achieved by developing the intra-prediction mode of the current block; developing adjacent samples including the left adjacent samples and the upper adjacent samples of the current block; developing reference samples to predict the target sample from the adjacent samples based on the position of the target sample of the current block and the prediction angle of the intra-prediction mode; determining the interpolation filter for the target sample and developing a target sample prediction sample based on the interpolation filter and the reference samples.
EFFECT: increased efficiency of image decoding.
