注：系统树分支点处的数字代表系统树的自展值(1 000次重复)；标尺长度代表遗传距离。

Note: the Numbers on the branch points of the phylogenetic tree represented bootstrap values of the tree (1 000 replicates); Scale length represented genetic distance.

先通过预处理提取出血管并进行三维细化，再递归跟踪血管骨架生成特征树并进行遍历提取出血管的分支点和端点。

The vessel skeleton was recursively tracked to generate the feature tree and the tree was traversed consequently to pick up the branch points and end points.
