초록

There are nine modes of the intra prediction for $4{\times}4$ luma blocks in H.264/AVC, each of which is identified by the prediction direction and reference pixels. Especially, mode 8 is modified to enhance coding efficiency, considering that the mode does not use left-bottom pixels although they are available. That is, we propose a modified intra prediction method of mode 8 which uses left-bottom pixels if available.
