轮廓

Discovered by the 19th century French explorer Henri Lhote, these figures were so unusual he dubbed them Martians, explaining their contour is simple, unartistic, and with rounded heads; their only detail is the double oval at the figure's center, which evokes the image we currently have of Martians.

这些轮廓是由十九世纪的法国探险家Henri Lhote发现，是如此不寻常，他称他们为火星人，解释他们的轮廓是简单，非艺术性和拥有圆形的头，他们仅有的细节就是轮廓中央的两个椭圆形，唤起了我们当前对火星人的想象。

A GVF Snake is presented here to solve the poor convergence to boundary concavities which exists in the traditional Snake model.

主动轮廓线模型存在严重的缺陷——轮廓初始化问题和无法提取凹陷的目标轮廓。

The roughness shape of ceramic machining surface is analysed by four kinds of test methods: surface profile, scanning electron microanalyses, bearing ratio curve and profile ratio of peak to valley. Ceramics are machined by"plateau honing"to obtain the plateau property and wearability of machining surface. The machining surfaces own its functional surface.

采用表面微观轮廓、扫描电镜观察、表面支承长度率曲线以及表面轮廓峰谷比等四种研究方法，详尽分析了陶瓷材料加工表面的轮廓形状特征，并采用平顶珩磨加工方法，获得陶瓷加工表面的平顶特性，提高了加工表面耐磨性。

The forecast algorithm is based on the peculiarity of 3D images i.e the deformation of the contour along the space or time axis is continuous in 3D images. The forecast algorithm analyzes the trend of the deformation of the contour in the segmented images, then prognosticates the location and the shape of the contour in the next image.

三维图像中物体的轮廓沿着空间轴或时间轴的位移和形变是连续的，该算法根据这一特性，利用前几幅图的分割结果来预测当前图像中物体轮廓的位置和形状，弥补了主动轮廓模型搜索范围小的缺点。

The estimation of forming part"s sideline The estimation of forming part"s sideline is significant in weld and assembly process, the paper puts forth two kinds of method to realize quantitative analysis for the deformed sideline, one is using line contour error to estimate deformed sideline combined with GA and taking the value of line contour error as target to check whether it is in the range of precision; The other is comparing curvature and torsion of design model with curvature and torsion of deformed model to check the sidelines precision.

冲压件边线变形的评价。冲压件的边线变形的评价在焊装工艺中有着重要意义，本文提出两种方法来实现冲压件边线的变形评价：一是借鉴线轮廓度评定的方法，结合遗传算法计算出边线的线轮廓度，并以线轮廓度值作为边线是否满足要求的评价指标：二是通过比较变形前后曲线的曲率和挠率来评价边线的变形情况。

In order to describe the lip contours in a lip reading system automatically and fleetly,orthogonal compression transformation was applied to the feature extraction of lip contours.

为了能够自动而且快速地获取唇读系统中所必需的唇形轮廓特征，提出了将正交压缩变换的方法用于唇形轮廓的特征提取，并对得到的唇形轮廓曲线进行了分析研究。

At carving techniques, the principal has incised (outlined contours, as outlined in the painting), and implicit pressure from the bas-relief, deep relief,yuan diao luo diao , minus Nimodipine carving (yin xian characterize the image of contour, and image the open space outside the contour cutting of low-leveled), etc..

在雕刻技法上，主要有阴刻（刻划轮廓，如同绘画中的勾勒）、压地隐起的浅浮雕、深浮雕、圆雕、镂雕、减地平雕（阴线刻划形象轮廓，并在形象轮廓以外的空地凿低铲平）等。

Compared with the electronic technique, laser engraving method has many benefits, one of the network of xuetie shape, laser engraving of the concave-there are many network point shapes such as alignment, Hexagon, square, round, pillow-shaped, and so on.

与电子雕镂法相比，激光雕镂法有许多优不面，其一，网穴轮廓的多变性，激光雕镂不凸版可以拔取多栽网穴轮廓，如六边形，不方形、线形、方形、枕形等各栽轮廓。
