A double - iteration algorithm with variable threshold for global motion estimation 全局运动估计的阈值可变双迭代法
Variable threshold logic 可变阈值逻辑
Algorithm designing is base on traditional method and make amelioration . in this design , it adopts two variable thresholds , adds a moving window and r - r interval threshold 算法设计在传统的方法上提出改进,采用双可变阈值法,并增加了一个滑动时间窗和r - r间期阈值。
