1) Displaced frame difference
位移帧差
1.
By two dimension motion estimation and computing the displaced frame difference,the motion object can be separated form the still background,and then morphological filtering is used to gain the better segmentation result.
首先进行图像序列二维运动估计并计算位移帧差 ,然后 ,将位移帧差作为将运动物体从静止背景中分离出来的标准进行分割 ;最后对分割结果进行形态滤波。
2) Absolute displaced frame difference
绝对位移帧差
3) differenced phase between multi-frames
多帧相位差
4) inter frame displacement
帧间位移向量
5) square difference of displacement
位移方差

对地震激励下的结构的调谐减震控制 (TMD)进行分析 ,考虑了土体与结构的共同作用 ,通过拉普拉斯变换 ,采用传递函数的解法 ,在不同参数情况下 ,探讨了有、无TMD结构体系的主结构位移方差随主结构一阶固有频率的变化规律。
6) differential displacement
差异位移
1.
Based on recent research on Neogene and Quaternary in Bohai Bay Basin,author proposes a new explanation: the reverse drag anticlines and associated single or complicated y-shaped normal faults resulted from the modes of movement and differential displacement by regional extension,and it is emphasized that the characteristics and origin of reverse drag anticlines are different from negati.
根据近年来对于渤海湾新近纪—第四纪盆地的研究,提出了一种新的解释,即逆牵引构造和伴生的简单或复杂y字形正断层组合是由于区域伸展作用下不同运动方式和差异位移产生的,并强调指出,逆牵引背斜构造与走滑作用产生的负花状构造在构造特征和成因上是不同的,不要把这两者混为一类构造。
