摘 要: 通过多种数学形态学算法的综合利用,实现对腹部器官及相应血管的提取。首先,利用复合型数学形态学梯度算法和条件膨胀算法实现器官提取;其次,利用多尺度结构元素的Top-Hat变换算法和阈值实现血管提取;最后利用迭代腐蚀算法和测地影响实现粘连组织器官的分离。实验结果表明,采用这种方法实现的提取速度快,提取的器官与血管效果好。 This paper introduced a combination utilization of multi-mathematical morphology algorithms to realize the extraction of abdominal organ and its relative blood vessels. This paper first combined compound mathematical morphological gradient algorithm with conditional dilation algorithm to extract organs. Then, it applied multi-dimension structure Top-Hat algorithm and Threshold Value for the extraction of relative blood vessels. At last, used recursive erosion algorithm and geodesic influence for separating touched organs. Those methods above are quick for extracting, and the organs and blood vessels' extraction effects are good.
