特徵

The system consists of four stages: foreground segmentation, head extraction, facial component identification and recognizability measurement.

我们所提出的系统，分成为四个部份：前景侦测、头部区域撷取、人脸特徵侦测、可辨识度计算。第一个部份，先以一个统计式的方法来建立背景模组。

A Cox Regression model for recurrent event data was used for the analysis of maternal and paternal socio-demographic characteristics in relation to birth intervals. The risks of shorter birth intervals were expressed as hazard ratios .

利用分析重覆事件的考克斯模型探讨双亲社会人口学特徵对出生间隔的影响，解释变项的效果以风险比及相关的95%信赖区间表示。

This "pair" is easy to tell from other warblers by combination of greyish crown, green upperparts, narrow and very white wing bars, rather white supercilium and rather clean white underparts, pink legs, more skulking habits and frequently-given whistled "tsUUI" notes which to my ear sound very like the call of Daurian Redstart.

这两种柳莺可以和其他柳莺很容易区别，透过它们灰色的冠，绿色的体上，很细又很白的翼带，还算白的眉线，还算乾净、白色的体下，粉红色的脚，喜爱躲藏的习性，以及经常听到，且对我来说很像黄尾鸲叫声的「tsUUI」声音等特徵。

By the use of the obtained relationship between reflectively and frequency, the effects of thickness, material coefficients and viscoelastic damping of outer shell on the scattering characteristics of the structure were calculated and analyzed.

利用已得到的散射率函数，计算并分析了外层壳的厚度、材料常数、粘性阻尼等对双层球壳散射特徵的影响。

Optical time-domain reflectometry located the regions where optical attenuation occurred due to leakage; optical power meter acquired the transmitted power at the end of fiber, and these events could be identified according to the characteristics of signals.

在光入射端，用光时域反射计对上述事件引发的损耗进行定位；在光输出端，用光功率计检测光功率的变化，并根据信号特徵来判定事件的类型。

For getting the major characteristic edges without confusions by undesired structures like muscle edges, we integrate a star-like edge detection filter named "Asterisk Filter" with the Canny Edge Detection in the image preprocessing. In addition, we also propose a new contour tracking method named "One-Pixel Rolling Ball Contour Tracking" for getting the boundary information in a binary image which is a link-list data structure. Instead of using a regression curvature estimator, PCA is used for better curvature estimation from a discrete bony contour.

为了从影像上取得骨头特徵边缘，将不重要的肌肉视为杂讯滤除，我们引用一种星形滤波器－Asterisk Filter，搭配Canny边缘检测法，做为这类影像的前处理；另外，为了将骨头的边缘精确地追踪出来，我们提出滚球边界追踪法，来对二值化影像进行边缘追踪，藉此获得边缘的串列资料结构；我们采用以主成分分析(Principle Component Analysis，简称PCA)取代原本以回归方法来计算的曲率，以取得更佳的曲率估测值，其可提高计算之参数的准确性。

The image characteristics of circular structured light stripe in a micro-object inner surface vision inspection system are analyzed and the false stripes can be divided into two kinds of diffuse reflection and regular reflection.

分析微小物体内表面视觉检测系统中圆形结构光光条图像特徵，将干扰光条分为漫反射和镜面反射两类。

Through individual species-area relationship analysis and Monte Carlo simulation, the species-area patterns from individual view were estimated; as such, every woody species was distinguished as a diversity accumulator, repeller, or neutral species. These species specific characteristics then were treated as implication for the strength of competitive interactions in the study site.

藉由个体物种面积关系分析与蒙地卡罗模拟，我检测个体观点之物种面积关系，并由此将所有树种区分为多样性累积者、多样性排斥者以及多样性中性者三类，再以这些物种特徵来推论种间竞争作用的重要性。

This species can be distinguished from other congeners by its resupinate strobili, long-tailed apex of ventral trophophyll and distinctly white-callous margin of dorsal one.

此物种可藉其转置的孢子囊穗、营养腹片先端长尾与背具有显著的白色软骨质边缘等特徵，而与台湾产其他种区分。

Standard features include a precision-engineered revolutions per minute controller, a durable rotor brake, an auxiliary fuel system to increase its versatility and enhancing ring circuit, and a high-quality voice communications device driver.

标准特徵包括一个精密设计的每分钟转数控制器，一个耐用的旋翼制动装置，一个辅助燃料系统以增加它的多功能性及加强环形电路，以及一个优质的声音驱动通信装置。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
