分别为基于线性预测的准菱形搜索算法(LPPDS)和基于空间预测的多参考帧选择算法。
They are line prediction based pseudo-diamond search (LPPDS) algorithm and spatial prediction based multi-frame selection algorithm.
特别是对于参考帧的选择、宏块分割的方式、预测方向的选定，都达到了自适应的效果。
Using these coding tools, H. 264 achieves significant performance. Especially for reference frame, block size, and prediction direction, it can adaptively do the selection.
