查询词典 contour machine

For the image with random field feature, the description language is probability distribution model, and the description length equals the negative base-two logarithm of the probability of the image data; For the region homogeneity properties of active contour, the description language is chosen as a sign gradient map, and the description length is the summation of sign gradient inside the active contour; For the active contour regularity, the description language is smoothness, and the corresponding description length is the length of active contour curve.

随机场图像的描述语言采用概率分布模型，描述长度是围道内外区域中图像数据概率的以2为底对数的负数；活动围道区域一致性的描述语言为有符号的梯度图，描述长度是围道内区域有符号梯度的总和；围道形态的描述语言采用平滑性，描述长度正比于围道的长度。

The method consists of tree steps: enhancement, contour segmentation, and feature selection. In this study, our method is able to enhance the signals from masses and extract the useful contour feature from the segmented regions. The ruler method of fractal dimension computed for each case was used to form a contour feature. These feature measures can be input to a classifier based on sorting. The experimental results show that our scheme can provide useful contour extraction for spiculation structures in mammographic images.

我们的研究目的是在乳房的X光影像中选取肿瘤怀疑的区域，分成三步骤，影像前处理、轮廓分割、特徵选取，找出具有星状物轮廓的肿瘤，我们的方法首先强化肿瘤组织，接著有效分割出肿瘤的轮廓，最后利用规则式的碎形维度计算其轮廓特徵值，接著排序分出肿瘤轮廓类别，实验结果证明我们的方法可有效侦测出星状物肿瘤轮廓及其特徵。

The active contour model is a powerful image segmentation method for representing image contour, but it has three severe difficulties. First, active contour model highly depends on its initial position. Second, active contour model lacks the ability to handle boundary concavities.

动态轮廓模型(active contour model； ACM)是一种功效强大的影像分割描绘方法，但却具有三个严重的缺点：第一、此模型非常依赖待描绘图形的起始位置，第二、此模型缺乏进入图形凹陷处的能力，第三、此模型有停滞在局部能量极小值的倾向。

In this paper, a boundary chain code tracing method is used to extract the contour information, the process of thinning, de noising, and encoding for contour are realized at one time, so a 1D string represented the 2D contour shape information is obtained, then a contour matching method based on chain code is presented.

首先利用边界链码的跟踪技术，提取出二维碎片的轮廓信息，同时对轮廓线进行细化、去噪和编码处理，得到二维轮廓线的一维链码信息描述，并在此基础上提出一种基于链码的二维碎片轮廓匹配方法。

For reconstruction from contours, this dissertation uses Active Contour Model to check the boundary contours. The algorithm can generate single, continuous and close contours quickly. For reconstruction from voxel, this dissertation presents an algorithm to trace the boundary contours from segmented regions based on Active Contour Model. The algorithm can trace the contours of inter and outer connected multi-regions correctly and accurately, and can prevent tracing from jumping out to the neighbor region, also can define the contour precision and contour key points actively as snake is growing up.

对于基于轮廓线的表面重建，利用主动轮廓模型（Active Model，又称Snake Model）来完成断层图象上目标轮廓的提取，可以获得单象素连通的封闭的目标边界轮廓；针对基于体素的表面重建中实施了分割后的体数据，提出了一种基于主动轮廓模型完成二值图象中轮廓跟踪记录的方法，可以对同属于重建目标的内外邻接多区域进行正确和准确的边界轮廓跟踪，使得在跟踪当前轮廓时不会跨越到相邻轮廓，且主动轮廓的精度可以根据参数交互决定，尤其是能够在主动轮廓成长的同时主动定义轮廓关键点。

From the development and present status of automatic mapping contour maps, we know that the technology of automatic mapping contour maps which contains faults especially cross bedded faults was developed slowly, which are part of contour maps. In the process of our factual work, the phenomenon of half-handcraft mapping contour maps containing singular and cross-bedded faults is ubiquitous.

从等高线图自动绘制的发展历史及现状可以看出，断层等高线图是平面等高线图的一部分，含断层等高线图的自动绘制，尤其是带交叉断层等高线图的自动绘制技术发展缓慢，半手工绘制单一断层和交叉断层的等高线图的现象还普遍存在。
