Abstract
Coding a current block using a directional intra-prediction mode is described. A filter to apply to reference pixels peripheral to the current block is determined using a prediction angle of the intra-prediction mode and a size of the current block. The reference pixels are filtered using the filter to generate modified reference pixels, and a prediction block is generated for the current block using the intra-prediction mode and the modified reference pixels.
