The dimensionless of the leakage water temperature and the stratum temperature in real Spaces were obtained by the contour integration method.

再利用围道积分对其进行逆变化，得到无量纲渗漏水温度及地层温度解析解。

The recursively increasing threshold method is first proposed. Then the method of contour integration region labeling and the design of intensity homogeneity segmentation criterion are presented.

介绍了围线积分法区域标号和灰度均匀度分割准则的设计。
