They are line prediction based pseudo-diamond search (LPPDS) algorithm and spatial prediction based multi-frame selection algorithm.

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。

Experimental results show that multi-reference-frame prediction does not improve coding performance but involve heavy computing cost in most cases.

实验结果表明，多参考帧预测在绝大多数情况下不能改善编码效率，反而引入了繁重的计算开销。
