轮廓

In profile the upper outline of the skull is nearly in the same plane as that of the foreface.

脑袋的上轮廓与前脸的上轮廓几乎处在同一平面。

Discrete Fourier Transform and Discrete Cosine Transform were used to get the descriptors of lip contours in the asymmetrical lip contour model.Then the Hidden Markov Model was trained using two kinds of descriptors as the eigenvectors of lip contours.

通过离散傅里叶变换和离散余弦变换分别得到描述唇形轮廓特征的傅里叶描述子和离散余弦变换描述子，然后将两类描述子作为唇形轮廓的特征向量，采用隐马尔可夫模型进行学习和识别。

Compared with region relationship tree proposed by Fub,global contour of image can be described in our methods and it made the relationship of contours more accurately and integrally.

在图像处理领域，轮廓也是图像中目标的基本信息，通过轮廓的提取和分析，可以得到图像中感兴趣目标的相关信息。

Some applications of the Bezier curve to computer graphics are introduced in this paper. These include generating flowered patterns approximate drawing of profile of machine parts, designing the shape of industrial products with free curve, making three-dimensional picture of ratators with the Bezier curve as the generating line and plotting charts by smoothing out the graphs of discrete data of scientific experiments.

本文介绍Bézier曲线在计算机绘图中的某些应用，例如生成花纹图案，近似绘制机件的圆弧轮廓图，工业产品自由曲线轮廓的构形设计，生成以Bézier曲线为母线的旋转体三维图象，利用Bézier曲线的凸包性对离散的科学实验数据进行平滑处理绘出数据图表等。

Geodesic active contour model is one of models for the tracking of moving objects.

We selected the geometric and geodesic active contour model of Caselles as our researching objects in next steps .

在诸多改进的数学模型中，选取了Caselles等人的几何活动轮廓模型和测地线活动轮廓模型作为我们进一步研究的对象。

We decompose curvature signal with wavelet at first and then use its low frequency coefficients as new smooth curvature signal, which is used to construct a G^2 continuous piecewise rational cubic Bezier curve with (Geometric Hermite Interpolation, GHI) GHI method subsequently.

针对在逆向工程的实践中常见的轮廓线的光顺问题，给出了一种先对曲率图进行小波分解，提取其低频部分作为新的曲率图，并利用几何Hermite插值方法，生成G^2连续的分段三次有理Bézier曲线，从而重建出光顺的产品轮廓曲线的新方法。

It makes full use of the direction information which goes along with the process of the optimum edge detection, and two algorithms: region statistics and center collection are designed to realize the enhancement of the central information by converging the outline of gobbet object to the center of it,and at the same time it effectively resolves the problem of cutting up the outline of the object and attribution of it; the algorithm of barycenter convergence and gobbet feature decision are used to realize the accurate location of the central position.

该方法充分利用最佳边缘检测过程伴生的方向信息，设计了区域统计、中心集聚算法，将团块目标轮廓信息会聚到目标中心以实现中心信息增强，同时有效地解决了目标轮廓分割及归属问题；采用重心聚合和团块特征判定算法，实现中心位置准确识别定位。

After a master glyph outline is scaled from the EM grid to the current character dimensions, the hinter or grid-fitter is in charge of aligning important outline points to the pixel grid.

在主字形轮廓从EM网格缩放到当前字符大小后，hinter负责对齐重要的轮廓点到象素网格。

Comparing with Galaxy, M31 has much lower gas and SFR profiles, but their total dynamic: mass are comparable. That means M31 needs faster star formation rate and infall rate (namely shorter infall time scale) in order to consume more gas . However, the low nietallicity and flat abundance gradient require lower star formation efficiency, and few metal poor stars means the infall time scale can not be very short.

与银河系相比，M31有着较低的气体轮廓及SFR轮廓，但其动力学总质量与银河系相当，这便要求有较大的SFR及较快的下落速度来消耗更多的气体；然而，较低的金属丰度及丰度梯度意味着SFE不能过高，贫金属星很少又暗示着下落时标不能很短。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
