  • Publication number: 20210051345
    Abstract: A video coder that implements illumination compensation is provided. The video coder receives a first block of pixels in a first video picture to be coded as a current block, wherein the current block is associated with a motion vector that references a second block of pixels in a second video picture as a reference block. The video coder performs inter-prediction for the current block by using the motion vector to generate a set of motion-compensated pixels for the current block. The video coder modifies the set of motion-compensated pixels of the current block by applying a linear model that is computed based on neighboring samples of the reference block and of the current block. The neighboring samples are identified based on a position of the current block within a larger block.

    Abstract: A method and apparatus for video coding using Intra prediction are disclosed. In one method, a first prediction sample in an immediately right column of the current block and a second prediction sample in an immediately below row of the current block are derived using angular prediction. The first prediction sample and a left column reference sample in the same row as the first prediction sample are interpolated to generate a horizontal predictor. The second prediction sample and an above-row reference sample in the same column as the second prediction sample are interpolated to generate a vertical predictor. The vertical predictor and the horizontal predictor are linearly combined to generate an angular-planar prediction sample. In another method, a first predictor is generated using angular prediction and a second predictor is generated using planar prediction. The first predictor and the second predictor are linearly combined to generate a fused Intra predictor.
