摘要 文中提出并实现了一种新的按光栅顺序扫描取点,然后进行边界跟踪的轮廓线提取算法,该算法是基于对CT医学图像前期预处理及边缘检测所得到的二值化图像而建立的。实例表明该方法可以获得更加精确的象素级边缘。 A creative algorithm is provided and fulfilled based on the binary- value image, which is obtained through preprocessing and edge detection, to fetch points by means of raster scan and to extract contours by border following. Examples show this new method can detect pixel contour more accurately.
