| 摘 要： | 针对传统V.S.分水岭算法存在的过分割现象,提出一种基于脊线的层级分水岭算法。通过对传统V.S.分水岭算法中浸没过程的适当改进,找到完整无冗余的区域脊线;再次修改浸没过程,仅对脊线进行多级迭代的分水岭再分割,即可完成区域分割。实验结果显示:该算法能处理传统V.S.分水岭算法的过分割现象,且计算速度较快。

| Abstract: | In order to avoid over-segmentation of the traditional V.S.watershed algorithm,a novel two-step hierarchy watershed algorithm based on ridge was presented.Step 1,the immersion process of V.S.watershed was improved so that the whole non-redundant ridges of an image′s regions could be found.Step 2,with the help of some other improvements in the immersion process of the V.S.watershed,these ridges were iteratively dealt with to complete the image′s final segmentation.The experimental results showed that the developed multistage watershed was an effective algorithm for solving watershed over-segmentation and for fast computing. |
