It is useful to research the qualities of every kind of frame vectors and their mutual relations.
这有利于研究每种类型的框架向量和它们的相互关系。
The reference frame is a past frame from which to grab pixels from and the motion vectors index an offset into that frame.
参考帧是过去的某个帧，可以从中提取某些像素，以及运动矢量偏移索引。
Compressed parameters include type of frame, type of macroblock, DC coefficients, and motion vectors.
算法中利用的压缩参数主要有帧类型、宏块类型、DC系数、运动矢量。
As for tracking, vectors between the last interested objects in previous frame and moving objects in current frame are established to follow the present interested objects.
在后续帧中通过建立前帧感兴趣运动对象与当前帧中各运动对象的帧间向量来跟踪当前帧中感兴趣的视频对象。
Then the features of color histogram and MPEG-7 edge histogram of each key frame are computed and the feature vectors of shot key frames are formed.
然后计算关键帧的颜色直方图和MPEG-7边缘直方图，以形成关键帧的特征；
Using Lorentz transformation, a momentum vectors diagram of the emitted particle in laboratory frame and center-of-momentum frame is given in relativistic two-body reaction.
利用洛伦兹变换，画出了相对论下二体反应实验室系和动心系出射粒子动量的关系图，并利用关系图，对不同情况下的出射粒子能量分布作了讨论。
