摘要:

本文提出了一种新的确定块匹配运动估计算法搜索区域的方法。该方法对每个帧块自适应地寻找搜索区域。该搜索区域类似于全搜索(FS)算法的搜索区域,但是对于帧的大多数块来说较小。因此,该算法在规则性方面类似于FS,但具有更小的计算复杂性。利用块运动矢量之间的时间和空间相关性来寻找搜索区域。匹配的块是从预测向量所设置的矩形区域中选择的。仿真结果表明,该算法的速度至少是FS算法的7倍。

英文摘要:

This paper suggests a new method for determining the search area for a motion estimation algorithm based on block matching. The search area is adaptively found in the proposed method for each frame block. This search area is similar to that of the full search (FS) algorithm but smaller for most blocks of a frame. Therefore, the proposed algorithm is analogous to FS in terms of regularity but has much less computational complexity. The temporal and spatial correlations among the motion vectors of blocks are used to find the search area. The matched block is chosen from a rectangular area that the prediction vectors set out. Simulation results indicate that the speed of the proposed algorithm is at least seven times better than the FS algorithm.
