摘要 提出一种面向快速全局运动估计的亮度残差阈值方法,通过统计特性推导出适用于不同分辨率大小视频编码的全局运动估计阈值因子。在保证视频编码性能的前提下,加快全局运动估计收敛于稳定值,实现快速全局运动估计的目标。实验证明,该方法具有较好的鲁棒性和准确性。 This paper proposed a luminance residual error threshold method oriented to fast global motion estimation. Deduced a set of threshold factors that fitted for diverse resolution video coding according to the statistics. It could converge rapidly the global motion estimation and achieve the fast global motion estimation while maintaining the coding performance. Simulated results show that the proposed method is robust and accurate.
