  • Method for determining predictor blocks for a spatially scalable video codec
    Patent number: 10944966
    Abstract: The invention relates to method for determining predictor blocks of a first resolution layer image from blocks of a second resolution layer image of a spatially scalable video codec, wherein a resolution of the first resolution layer image is higher than a resolution of the second resolution layer image, the method comprising: up-scaling each block of the second resolution layer image to a corresponding block of an up-scaled second resolution layer image; and filtering each block of the up-scaled second resolution layer image by a sharpening filter to obtain a predictor block of the first resolution layer image.

  • Processing reference samples used for intra-prediction of a picture block
    Patent number: 10728548
    Abstract: A method of coding implemented by a decoding device. The method includes determining a prediction direction for a current block, determining a propagation distance along the prediction direction, the propagation distance measured between a pixel to be predicted in the current block and a reference sample adjacent to the current block, selecting one of a plurality of filter coefficients based on the propagation distance, predicting the pixel in the current block using a filter and the one of the plurality of filter coefficients that was selected, and displaying an image including the pixel that was predicted.
