METHOD AND DEVICE FOR DECODING IMAGE BASED ON INTRA PREDICTION IN IMAGE ENCODING SYSTEM Russian patent published in 2020 - IPC H04N19/593 H04N19/105 

FIELD: data processing.

SUBSTANCE: invention relates to a method and an apparatus for decoding an image in accordance with intra prediction in an image encoding system. Disclosed is a method of decoding video, performed by a decoding device, which comprises a step of obtaining an intra prediction mode for a current block, a step of obtaining upper neighbouring samples of a plurality of rows and left neighbouring samples of a plurality of columns, a step of obtaining one row of upper reference samples based on upper neighbouring samples, a step of obtaining one column of left reference samples based on left neighbouring samples and a step of generating a prediction sample for the current block using at least one of the upper reference samples and the left reference samples in accordance with the intra prediction mode.

EFFECT: high-efficiency image compression for efficient transmission, storage and reproduction of high-resolution image information and high quality.
