...文最后研究了时间分辨率转码,在已有的运动矢量重建算法的基础上,结合MPEG-4到H.264转码的特点,改进了活动主导运动矢量选择(ADVS)算法,提出了根据压缩码流中当前块的编码模式和丢弃帧中参考块的编码模式来预测当前块再编码模式的方法,使模式搜索的范围缩减50%以...

在参考运动矢量选择步骤中，选择与当前块相邻的左下块、正上块和右上块的运动矢量作为当前块的运动矢量。
In step for selecting reference motion vectors, selecting lower left block, upper block, and upper right block adjacent to current block is as motion vectors of current block.
据我所知道的，它基于临近的MV选择了一个算术编码上下文，然后决定使用哪个运动矢量，或是否计算出一个差值来代替。
As far as I can tell, it chooses an arithmetic coding context based on the neighboring MVs, then decides which of the predicted motion vectors to use, or whether to code a delta instead.
根据运动矢量场自适应选择搜索起始点和不同的搜索策略进行搜索，同时设定阈值对静止块直接中止搜索。
Then the initial search point and 2 search strategies were adaptively chosen according to the motion vector field, and an threshold was also selected to detect stationary blocks.
