帧内预测模式编码使用基于临近块模式的算术编码上下文。

Intra prediction mode coding is done using arithmetic coding contexts based on the modes of the neighboring blocks.

因此为了降低帧内预测模式选择的计算复杂度，本文改进了帧内预测模式选择算法。

In order to reduce the complexity, this paper proposes a fast arithmetic for intra-prediction mode selection.

对于帧内预测模式，也以块为单位，采用一种“放大的帧内预测模式”进行放大处理。

And to the intra prediction model, we also take block as the unit and enlarge the prediction-frame by using an "enlarged intra prediction model".
