Abstract: Video data may be palette decoded. Data defining a palette table may be received. The palette table may comprise index values corresponding to respective colors. Palette index prediction data may be received and may comprise data indicating index values for at least a portion of a palette index map mapping pixels of the video data to color indices in the palette table. The palette index prediction data may comprise run value data associating run values with index values for at least a portion of a palette index map. A run value may be associated with an escape color index. The palette index map may be generated from the palette index prediction data at least in part by determining whether to adjust an index value of the palette index prediction data based on a last index value. The video data may be reconstructed in accordance with the palette index map.

Abstract: Systems, methods, and instrumentalities are disclosed for discontinuous face boundary filtering for 360-degree video coding. A face discontinuity may be filtered (e.g., to reduce seam artifacts) in whole or in part, for example, using coded samples or padded samples on either side of the face discontinuity. Filtering may be applied, for example, as an in-loop filter or a post-processing step. 2D positional information related to two sides of the face discontinuity may be signaled. In a video bitstream so that filtering may be applied independent of projection formats and/or frame packing techniques.

Abstract: Cross-plane filtering may be used to restore blurred edges and/or textures in one or both chroma planes using information from a corresponding luma plane. Adaptive cross-plane filters may be implemented. Cross-plane filter coefficients may be quantized and/or signaled such that overhead in a bitstream minimizes performance degradation. Cross-plane filtering may be applied to select regions of a video image (e.g., to edge areas). Cross-plane filters may be implemented in single-layer video coding systems and/or multi-layer video coding systems.

Abstract: A multi-state memory and a method for manufacturing the same. A magnetoresistive tunnel junction is disposed on a spin-orbit coupling layer, and thermal annealing is performed after dopant ions are injected from a side of the magnetoresistive tunnel junction. The concentration of dopant ions in the magnetoresistive tunnel junction has a gradient variation along the direction that is perpendicular to the direction of the current and within the plane in which the spin-orbit coupling layer is located. Symmetry along the direction perpendicular to the direction of the current is broken. In a case a current flows into the spin-orbit coupling layer, resistance are outputted in multiple states in linearity with the current. The multi-state storage is achieved. It can meet a requirement on hardware of neural network synapses, and is applicable to calculation in a neural network.

Abstract: A block may be identified. The block may be partitioned into one or more (e.g., two) sibling nodes (e.g., sibling nodes BO and B1). A partition direction and a partition type for the block may be determined. If the partition type for the block is binary tree (BT), one or more (e.g., two) partition parameters may be determined for sibling node BO. A partition parameter (e.g., a first partition parameter) may be determined for sibling node B1. A decoder may determine whether to receive an indication of a second partition parameter for B1 based on, for example, the partition direction for the block, the partition type for the block, and the first partition parameter for B1. The decoder may derive the second partition parameter based on, for example, the partition direction and type for the block, and the first partition parameter for B1.

Abstract: The present disclosure provides systems, devices, and methods for determining prediction weight for merge mode. One exemplary method comprises: determining a weight for at least one of an inherited affine merge candidate, a constructed affine merge candidate, or a zero motion vector of a coding unit; and bi-predicting the coding unit based on the determined weight. The weight of a current coding unit can be determined through explicitly signaling a weight index in the bitstream, or through implicit derivation at the decoder side.

Abstract: The present disclosure provides systems and methods for inter prediction process in video data coding. One exemplary method comprises: selecting one of a DMVR process and a BDOF process, based on a video bitstream; and inter predicting an image block based on the selected process. The selection can be made either through explicit signaling, or implicit derivation at the decoder side. According to one exemplary method, selecting the one of the DMVR process and the BDOF process can be performed by selecting the one of the DMVR process and the BDOF process based on: a flag signaled at at least one of a coding unit (CU) level and a coding tree unit (CTU) level, or a merge candidate index associated with an extended merge candidate list.

Abstract: Overlapped block motion compensation (OBMC) may be performed for a current video block based on motion information associated with the current video block and motion information associated with one or more neighboring blocks of the current video block. Under certain conditions, some or ail of these neighboring blocks may be omitted from the OBMC operation of the current block. For instance, a neighboring block may be skipped during the OBMC operation if the current video block and the neighboring block are both uni-directionally or bi-directionally predicted, if the motion vectors associated with the current block and the neighboring block refer to a same reference picture, and if a sum of absolute differences between those motion vectors is smaller than a threshold value. Further, OBMC may be conducted in conjunction with regular motion compensation and may use simplified filters than traditionally allowed.

Abstract: Systems, methods and instrumentalities are disclosed for adaptively selecting an adaptive loop filter (ALF) procedure for a frame based on which temporal layer the frame is in. ALF procedures may vary in computational complexity. One or more frames including the current frame may be in a temporal layer of a coding scheme. The decoder may determine the current frame's temporal layer level within the coding scheme. The decoder may select an ALF procedure based on the current frame's temporal layer level. If the current frame's temporal layer level is higher within the coding scheme than some other temporal layer levels, an ALF procedure that is less computationally complex may be selected for the current frame. Then the decoder may perform the selected ALF procedure on the current frame.
