A prediction mode for a neighboring block may be determined based on the non-neural network-based intra prediction mode.

Abstract: At least a method and an apparatus are presented for efficiently encoding or decoding video. For example, parameters for a local illumination compensation LIC of a current block being encoded/decoded in a picture are determined based on spatially neighboring reconstructed samples and corresponding spatially neighboring reconstructed samples of at least one spatial reference block, wherein the at least one spatial reference block is a spatially neighboring block of the current block in the picture. For example, a flag enables/disables the spatial LIC for the current block. For example, the spatial LIC is applied to any of an Inter/Intra/IBC prediction. For example, multiple spatial reference blocks are used in determining the spatial LIC parameters. For example, spatially neighboring reconstructed samples of multiple lines are used in determining the spatial/temporal LIC parameters.

Abstract: Some series of ABT split are normatively forbidden in order to limit the number of allowed series of splits, in a way that refines the trade-offs between the amount of allowed split series and the compression efficiency. In particular, a reduced combinatory in terms of allowed split series leads to reduced encoder-side complexity, in the rate distortion search for the best block partitioning. The normative split restrictions provide that when successively using horizontal or vertical then vertical or horizontal asymmetric splits, the considered succession of two splits leads to isolating the sub-area of the input block that is three-fourths the size of the parent block in width and height. Additional embodiments condition allowed splits on transform size, block size, and temporal layer of the slice and slice type.

Abstract: In a video coding system, it is proposed to improve the intra prediction based on intra-block copy by allowing a decoder-side refinement allowing further refinement of the block vector obtained from IBC using a template matching process. In this template matching, the decoder searches in an iterative process the best match for the current block (L-shaped) template within the reconstructed area, adjacent to the block vector determined using the IBC 10 prediction. This technique allows to obtain a finer precision that what is possible with IBC while minimizing the amount of coding information. In at least one embodiment where a coarse precision is used for IBC, it allows at the same time to benefit from significant coding gain provided by IBC while providing a much finer precision with reduced signaling of the block vector.

Abstract: Systems, methods, and instrumentalities are disclosed for performing overlapped block motion compensation (OBMC). OBMC may be performed by considering sub-blocks within a coding block as an entire block if a motion field is uniform. OBMC may be performed on a coding block partitioned into multiple sub-blocks, using a block-based OBMC approach. The sub-blocks may be determined to have the same motion field, if the affine model associated with the block is translational. OBMC may be performed by subtracting OBMC from an original picture in the merge modes, using a block-based approach. A block coded in OBMC mode may be used in motion compensation, for example a fast merge pass of merge mode(s). The top band and the left band of the block may be subtracted from the input signal associated with the current block, and motion compensation may be performed on the block having the top and left bands subtracted.

Abstract: A video encoder or decoder processes portions of video using virtual temporal affine motion candidates. Under the general aspects, virtual temporal affine candidates are created using only the classical temporal motion buffer information, avoiding the storage of additional affine parameters in a temporal motion buffer. A motion field for encoding or decoding a video block is generated based on the virtual temporal affine candidates. In one embodiment, collocated motion candidates are rescaled by adjusting the picture order count of the determined motion field. In another embodiment, resolution adaptation is performed to enable a current motion buffer to correspond to a reference motion buffer.
