查询词典 contour forging

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.
