It is generally a good rule to execute merging and splitting of cells at the end of the layout formatting.
通常一个很好的做法是，布局格式完成后再进行合并和拆分单元格的操作。
Finally, we attain the result of segmentation after region splitting and region merging which can avoid the phenomena of leakage and get rid of the fake edge.
最后，通过区域生长和合并，防止了生长时出现泄漏现象，进一步去除伪边缘，得到了最终的分割结果。
CABVW keeps the balance between disk I /O bandwidth and the caching system by dynamically adjusting the values of merging -cache cost and splitting -cache cost.
