And, similarly to the LCS algorithm, to obtain S1 'and S2', you trace back from this bottom-right cell, following the Pointers, and build up S1 'and S2' in reverse.

而且，与LCS算法类似，要获得S1 '和S2 '，要从右下角单元格开始沿着指针回溯，反向构建S1 '和S2 '。

The algorithm first makes a top-down coarse location using the projection analysis of the edge density graph and then makes a bottom-up precise location based on the vertical edge linkage intensity.

该算法首先通过对边缘密度图进行投影分析进行自顶向下的粗定位，然后在此基础上利用垂直边缘的连接强度进行自底向上的精确定位。

The basic idea of the mining algorithm is to generate concurrent branch pattern from rough concurrent branch pattern. Bottom-up method is adopted in the process of pattern generating.

该算法的基本思想是在粗并发分支模式的基础上生成并发分支模式，在并发分支模式生成过程中采用自底向上的方法。
