  • Patent number: 11159806
    Abstract: Techniques are described using Position Dependent Intra Prediction Combination (PDPC) and multiple reference lines. For example, a video coder (e.g., an encoder and/or decoder) can predict an initial prediction sample value for a sample of a current block using an intra-prediction mode. The initial prediction sample value can be predicted from a first neighboring block and/or a second neighboring block of the current block. One or more reference sample values can be determined from at least one line of multiple lines of reference samples from the first neighboring block and/or the second neighboring block. At least one of the lines from the multiple lines used for determining the reference sample value(s) is not adjacent to the current block. A final prediction sample value can be determined for the sample of the current block, such as by modifying the initial prediction sample value using the one or more reference sample values.

  • Patent number: 11153598
    Abstract: Aspects of the disclosure provide methods and an apparatus for video coding. The apparatus includes processing circuitry that decodes coding information of a current block (CB) from a coded video bitstream. The coding information indicates that the CB is coded with a subblock-based affine motion model including affine parameters that are based on multiple control point motion vectors (MVs) for the CB. The processing circuitry determines, based on the coding information, whether to select a subblock characteristic for generating a prediction for a sample in an affine subblock of the CB based on a corresponding subblock MV. In response to selecting the subblock characteristic, the processing circuitry determines the subblock characteristic based on at least one of the affine parameters. The subblock characteristic indicates one of: (i) a subblock size used for generating the prediction for the sample and (ii) an interpolation filter type for the affine subblock.
