摘要
在分析Log算子作用原理的基础上,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,该算法是基于对医学图像前期的预处理所得到的二值图像而建立的。实验结果表明,该算法可以有效地消除噪声,大大地提高了传统方法的效率,显示效果良好。
Based on the analysis of the Log operator,a creative algorithm,which fetching points by virtue of raster scan and extracting contours with border following,is provided and fulfilled ground on the binary-value images obtained through preprocessing.The experiment results prove that the noise can be removed and the efficiency is greatly enhanced.The display performance is well.
