针对于移动视频编码标准(AVS-M)中运动估计模块的计算,本文提出了一种适用于AVS-M的改进型交叉搜索算法。该算法以传统的交叉算法为基础,通过对AVS-M运动矢量的研究和分析,针对传统优秀算法的不足,引入灵活的搜索窗口,有效的降低了运动估计的运算量。实验结果表明,该算法显著降低了复杂度,大大减少了搜索点数,具有较好的鲁棒性。 Aiming at the calculation of motion estimation module in Mobile Video Coding Standard (AVS-M), this paper proposes an improved cross-search algorithm for AVS-M. The algorithm based on the traditional crossover algorithm, through the research and analysis of the AVS-M motion vector, introduces a flexible search window for the lack of the traditional excellent algorithm, effectively reducing the computational complexity of motion estimation. Experimental results show that this algorithm significantly reduces the complexity, greatly reduces the number of search points, and has better robustness.
