摘要
文章通过对运动矢量分布的研究,在全局运动信息提取的基础上,结合准确可靠的运动矢量预测和尽早中止的技术,提出了一种基于全局运动的非对称十字矢量预测快速匹配算法。实验结果表明该算法在加速比上高于一些主要的快速算法,在不明显降低峰值信噪比的情况下,算法能极大地提高编码速度。
Based on the study of distribution of motion vectors inside video sequences,combined with more accurate motion vector prediction and early termination techniques,a new algorithm is presented named as the Global Motion Based Unsymmetrical-Cross Vector Predictive Fast Match Algorithm（GMBUCVP） in this paper,Experiments show that the speedup outperforms other well-known fast search algorithm.In addition,the proposed algorithm greatly speedup the coding procedure with slightly lower PSNR.
