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.
该算法采用交叉-准菱形搜索模板，并融合了搜索起点预测、半途中止准则和自适应搜索模式等技术。
The algorithm adopts a new cross-quasi-diamond search pattern and some effective techniques, which are composed of the prediction of initial search point, half-stop criteria and adaptive search modes.
