| 摘 要： | 提出一种二值图像边界矢量化算法,实现从图像到图形的自动转换.先通过边界跟踪算法获取二值图像的边界,并利用SUSAN方法计算出边界上的角点,根据距离关系计算角点间的普通控制点,最后运用角点和这些普通控制点的3次B样条曲线拟合边界.实验结果表明算法有效实现了图像矢量化,解决了边界矢量化问题,具有较强的实用性.

| Abstract: | We proposed an algorithm of boundary vectorization for binary images,which can convert an image into a graphic.The boundary tracing algorithm was exploited to extract the boundary of a binary image,and the SUSAN app-roach was also applied to detecting the corners on the boundary.In order to approximate the image boundary,the control points between two adjacent corners were determined by their offset distances.The cubic B-Spline curve was used to fit the boundary.The experimental results show that the propos... |
