摘要
对目前几种在图像分割领域得到较多应用的交互式分割、区域生长分割以及阈值分割算法进行了探讨 ,并且结合实际 CT片图例分别进行分割实验研究 ,得到较为满意和可用性强的结果 .实验表明 :阈值分割对于 CT切片的效果最好 ;区域生长分割适宜于对面积不大的区域进行分割 ,分割效果较好 ;基于动态规划的交互式分割算法比较复杂 ,计算时间较长 ,但对于边缘较平滑的区域 ,同样具有较好的实际效果 .几种算法的评估为其在
Interactive segmentation, region growing segmentation and thresholding segmentation are studied, which are used widely in image segmentation. These algorithms are applied in some experiments to deal with CT image and the satisfactory results are gotten. The results show that among these algorithms, thresholding segmentation does best in CT image segmentation; in dealing with relatively small images, satisfactory results can be got by using region growing segmentation; although more time will be needed in using interactive segmentation which is the most complex, it dose fairly well with images whose edges are relatively smooth. The evaluation of the three algorithms provides a scientific basis of the application of these algorithms.
