其次，针对扫描图像可能产生倾斜，论文采用了一种基于有向单连通链的表单倾斜检测与校正算法对倾斜图像进行校正。

Secondly, owing to the form image skew, a skew detection and correction based on the directional single-connected chain is adopted.

在分析跟踪文件中的调用链时，会构建一个连通矩阵，用来表示哪个函数调用了其他哪些函数。

As the call chain is parsed from the trace file, a connectivity matrix is built that identifies which functions call which other functions.
