摘要
对二值和多值图象的边界跟踪和逼近问题作了探讨;提出了可识别边界线上左右边缘点的边界跟踪算法、利用链码的矢量性的多边形逼近算法和二次Bezier曲线逼近算法。这些算法简单实用,效果较好。
This paper discusses the problem of contour tracing and approximation for bilevel images and grey level images. The contour tracing algorithm which can recognize those points on the left side and the right side of the contour is presented,and the polygonal approximation algorithm and the quadratic Bezier curve approximation algorithm are described,which utilize the direction of chain codes. These algorithms are simple,practical and give satisfactory solution.
