Chapter 2 proposes a fast GME method based on the principle of the symmetry elimination and difference of motion vectors to reduce the computational complexity of global motion estimation.

第1章绪论部分首先阐述了选题的意义，然后对国内外研究现状进行了综述并作了相应的总结，最后介绍了本课题的主要研究内容和论文结构。

To reduce the computational complexity of Global Motion Estimation, a fast GME method based on the principle of the symmetry elimination and difference of motion vectors is proposed.

摘要该文针对全局运动估计计算复杂度过高的问题，提出了一种基于运动矢量对消和差分原理的快速全局运动估计方法。

Different from traditional system protection models, such as access control matrix model, this theory describes the operations in system by functions of random variable vectors, build an analysis model of trusted system with three axioms, and analyze the information flow in the system by tracing the operation sequence of the system.

与访问控制矩阵模型等传统的保护系统模型不同，这一理论用随机变量向量的函数来描述系统操作，基于三条公设建立了可信系统的分析模型，并通过对系统操作序列的跟踪来分析系统中的信息流。

Similar expression of HCV core antigen on serial passages suggested that the complementation system of TMV-based vectors was stable in systemic infection and expression.

通过连续三次传代，这个系统都具有系统侵染的特性，且稳定地表达核心抗原。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
