摘要
提出一种改进的Live-Wire算法,结合迭代阈值分割算法对医学图像进行交互式分割。改进的算法避免了传统的Live-Wire算法对噪声敏感、不能有效地区分强弱边缘的缺点,并且减少了动态规划寻找最优路径的时间和盲目性,在不增加算法复杂度的同时,提高了图像分割的准确性。
This paper presented an improved Live-Wire algorithm, combined threshold segmentation approach to the interactive medical image segmentation. Improved algorithm avoided shortcomings , which was the traditional Live-Wire algorithm sensitive to noise, not effectively distinguished between strong and weak edge. And reduced the dynamic programming to find the optimal path for the time and blindness, without increasing the complexity of the algorithm, improved the accuracy of image segmentation.
