FIELD: image encoding and decoding.
SUBSTANCE: get the pointer value for the current block according to the bitstream. Get the value of the first parameter for the current block and the value of the second parameter for the current block according to the value of the pointer and the predefined lookup table, obtaining the value of the sampling distance for the sample that is in the current block according to the value of the first parameter and the value of the second parameter. The prediction value for the sample is obtained according to the sampling distance value for the sample, where the indicator is merge_gpm_partition_idx, where the first parameter is angleIdx, which represents the angle to split the current block, where the second parameter is distanceIdx, which represents the distance to split the current block.
EFFECT: improved compression ratio with minimal loss of image quality or no such loss at all.
