edge following meaning in Chinese
边跟踪
边界跟踪
Examples
- The main results in this paper as follows : first , a prototype of a shape - based image database retrieval system is completed , it can receive the query mode both by giving an example image and by sketching the desired object on the screen , second , five shape - based image retrieval methods are realized ; third , an algorithm based on triangulation for shape - based image retrieval is brought forward . in this algorithm , firstly , the edge of the original image is followed and the candidate corners in the original image are detected . then the counterpoints of the candidate corners in the result of edge follow are found , and the boundary corners whose counterpoints have been found are queued in the order of their counterpoints in edge follow
同时本文中主要完成了以下三方面的工作：完成了一个基于形状特征的图象检索的原型系统，可实现例子图象或徒手绘草图两种查询方式；实现了五种利用形状特征进行图象检索的具体方法，并对其进行了分析比较；并且在继承将三角剖分引入形状检索的思想基础上提出了利用三角剖分进行形状检索的一种新算法：先对原图象进行边界跟踪和角点检测；然后寻找初始角点在边界跟踪中的对应点，并对找到对应点的角点按其对应点在边界跟踪中的顺序进行排序；再对排序后的角点进行德洛内三角剖分，得到能表示目标真实形状的三角形序列；最后计算三角形序列的角度直方图作为形状特征，并进行相似性匹配。
