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. An apparatus determines, using the prediction angle, a filter to apply to the pixels peripheral to the current block; filters, using the filter, at least some of the pixels peripheral to the current block resulting in modified pixels; and generates a prediction block for the current block using the intra prediction mode and the modified pixels.
