摘要
常用的边界提取方法均没有将单个边界元素与整个边界相联系,结果不是丢失边界元素就是增加边界元素,使图像的边界变得不甚平滑.为此,在张弛法的基础上结合迭代算法,提出了一种新颖的算法,有效地解决了这一问题,从而得到了高精度平滑的边界图像.
The normal method of image edge detection does not connect each element of edge with the whole edges, therefore, there is neither losing the element nor retaking it , which make the edge rough. The paper presents an new method to solve the question by using Strain-loose method, and obtain a clean edge.
