Abstract: Aspects of the disclosure provide methods, apparatuses, and non-transitory computer-readable storage mediums for video encoding/decoding. An apparatus includes processing circuitry that partitions a current block of a current picture based on a geometric partitioning mode (GPM). The current block is partitioned into two partitions in the GPM mode. Each of the partitions is associated with a respective predictor. A weighting index for a sample of the current block is determined based on a position of the sample. A weighting factor is calculated based on the weighting index of the sample according to an equation that converts the weighting index to the weighting factor. The sample is encoded based on the weighting factor and the predictor corresponding to the sample.

Abstract: A method of video decoding performed in a video decoder is provided. In the method, coded information of a current block is received from a coded video bitstream. The coded information includes a context-coded syntax element associated with the current block. The syntax element indicates a decoding parameter of the current block. A context-based adaptive binary arithmetic coding (CABAC) context model associated with the context-coded syntax element is determined based on decoding parameters of more than two spatially neighboring blocks of the current block. The context-coded syntax element is decoded based on the determined CABAC context model associated with the context-coded syntax element. The current block is reconstructed based on the decoded syntax element.

Abstract: A symmetric affine mode is applied to a current block. First affine parameters of a first affine model of the symmetric affine mode are determined. The first affine model is associated with the current block and a first reference block of the current block in a first reference picture. Second affine parameters of a second affine model of the symmetric affine mode are derived based on the first affine parameters of the first affine model. The second affine model is associated with the current block and a second reference block of the current block in a second reference picture. The first affine parameters and the second affine parameters have one of opposites signs, inverse values, and a proportional relationship. Control point motion vectors (CPMVs) of the current block are determined based on the first and second affine models. The current block is reconstructed based on the determined CPMVs.

The plurality of affine motion parameters is not included in the coded video bitstream. Control point motion vectors of the affine model are determined based on the derived plurality of affine motion parameters. The current block is reconstructed based on the derived affine model.

The processing circuitry reconstructs the current block based on the selected one of the integer motion vector, the first interpolation filter, and the second interpolation filter.
