Abstract
Coding a current block using a directional intra prediction mode is disclosed. The intra prediction mode includes a prediction angle and uses pixels peripheral to the current block to generate a prediction block. A method includes determining, using the prediction angle, a filter to apply to the pixels peripheral to the current block, filtering, using the filter, at least some of the pixels peripheral to the current block resulting in modified pixels, and generating a prediction block for the current block using the intra prediction mode and the modified pixels.
