目标识别

One algorithm,isoperimetric algorithm based on graph theory is applied and researched on image segmentation.Firstly,isoperimetric algorithm is applied in still image segmentation,and the result is compared with two methods based on edge detection and region detection.

1引言图像分割是图像处理领域和计算机视觉中的一个基本而关键的问题，其目的就是将人们感兴趣的目标从图像背景中提取出来，为后续的分类、跟踪、识别、处理等提供基础。

This paper laid the foundation for target detection, classification and recognition by the study on micro-Doppler effect.

本研究为应用微多普勒效应实现目标的探测、分类和识别奠定了基础。

Detecting and identifying formation lithology direct from seismic data is one of destination in seismic exploration.

地层岩性的检测和识别一直是地震勘探追求的目标之一。

Taking the solution for maximum and minimum values as target,by means of pattern recognition the eigen-values of massive data related to power transmission capability are extracted for the security check of power transmission capability .

以求取最大值和最小值为目标，采用模式识别方法提取输电能力中涉及到的海量数据特征值，用来进行输电能力安全校核。

An optimization model was established for identifying the soil hydraulic properties. The optimization objective was the minimum mean square deviation of simulation between measured and observed values of soil water content, and the constraint conditions were the upper and lower limit values of empirical soil hydraulic conductivity and water diffusion coefficients.

该文以反映土壤含水率实测值和计算值吻合程度的均方差最小为优化目标，以土壤导水率和扩散率经验参数上下限为约束条件，建立了土壤水分运动参数识别的优化计算模型。

Based on the ability of neural network in classification and recognization, a feed-forward multi-layer neural network is applied in the diagnosis of adhesive bond quality between metallic and nonmetallic components of a pressure vessel through acoustic feature extraction in the frequency domain, based upon the acoustic response on knocking the pressure vessel.

本文基于神经网络对目标的识别与分类能力，用简单的敲击法获取了某压力容器的声响应信号，通过对声信号的频域特征提取，应用前馈多层神经网络对压力容器的金属与非金属部件之间的粘接质量进行了诊断。

We applies the idea of influence analysis to identify the target area with high deposit of Coalbed Methane, and write a series of computer codes.

与实际相结合，用影响分析的方法识别煤层气富集靶区及其勘探目标的评价。

The pitch restriction between successive frames of speech is imposed to get rid of misjudgement in the ...

试验表明，该方法在信噪比很低的条件下，仍能较准确地识别出目标语音声调，并能在双话者同时发音的情况下实现各自的声调分离

"In this study, antepartum dental radiography in pregnant women was associated with an increased risk for a LBW infant, especially a TLBW infant," the authors write."Since women may not always be aware of their pregnancy status, it may not be possible to eliminate all dental radiography during pregnancy, but if this goal could be achieved and if the identified association is causal, the prevalence of TLBW infants could be reduced by up to 5%.... The notion that very low-dose radiation exposures to nonreproductive organs in expectant mothers are safe needs to be investigated further."

研究人员表示，在这项研究中，怀孕期妇女分娩前牙科X光摄影与LBW新生儿的风险增加联结在一起，特别是TLBW，由於妇女不能总是注意到她们的妊娠状态，也不可能在怀孕期间取消所有的牙科X光摄影，但如杲这个目标能达成，而且被识别的联想是偶然的，则TWBL新生儿的盛行率能依5%减少；此外，在妊娠妇女中，对非生殖器官极低剂量辐射曝露，是须进一步研究的安全需求概念。

This is the process necessary for numerically analyzing the effect on overall project objectives of identified risks.

这是对已经识别的风险对项目总体目标的影响进行数值分析所必需的过程。

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.

交际能力和语法的关系应该是目标与途径的关系。
