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.
