polygonal approximation meaning in English
多边形近似
Examples
- By the polygonal approximation method , a global approximation solution is constructed for the initial - boundary value problem of nonconvex scalar conservation laws with two - side boundary effect , and its convergence to the global weak entropy solution of the corresponding problem is proved
摘要使用折线逼近法，对具有两条边界影响的非凸单个守恒律初边值问题构造了整体近似解，并证明其收敛到初边值问题的整体弱熵解。 - Contraposed those characteristics of leather , after studying all kinds of algorithms of image segmentation , this dissertation chooses the techniques of thresholding methods of parallel region segmentation and edge tracing methods of serial edge segmentation to detect the contour of the leather image . then by using polygonal approximation method , we can convert the contour ' s form from image into graphics . it will make following arrangement works more convenient
本论文针对皮革图象的上述特点，在对各种图象分割算法进行研究后，选用了并行区域分割中的阈值化技术及串行边界分割中的轮廓跟踪技术，将皮革图象的边缘轮廓检测出来，并对该轮廓进行多边形拟合，使其由图象转换为图形，以便为后续排样工作提供方便。 - The new ideas of this dissertation mainly lie in two points . based on the research on the traditional edge tracing techniques , this dissertation presents an improved method according to lml rule . at the same time , studying the polygonal approximation methods , this dissertation also presents an improved and based on mergence method to image contour , and implements the transform of the contour from image to graphics preferably
本文的主要创新点在于：在研究传统轮廓跟踪技术? ? “爬虫”法的基础上，提出了基于lml规则的改进的轮廓跟踪方法；同时，研究了多边形拟合法，提出了基于聚合的改进的多边形拟合物体图象轮廓线方法，较好地实现了对边缘轮廓线的从图象到图形的转换。
