Abstract
Video coding and decoding apparatuses (and) capable of improving coding efficiency are provided. The video decoding apparatus () according to an aspect of the present invention is a video decoding apparatus () including a prediction unit () that derives a prediction image using a weight parameter derived from an angle variable, and a non-separable transform processing unit () that performs a non-separable transform, in which the non-separable transform processing unit () derives a set number (lfnstTrSetId) of the non-separable transform from split information (merge_gpm_partition_idx) of the GPM in a case that an inter-prediction mode is a GPM mode.
