17.1、对ROI进行操作----补充

*产生通过连通性分析后的区域ConnectedRegions

gen_ellipse (ROI_0, 194.454, 142.053, rad(22.0779), 68.1093, 95.939)

gen_rectangle1 (TMP_Region, 92.0538, 295.488, 320.485, 422.806)

union2 (ROI_0, TMP_Region, ROI_0)

gen_circle (TMP_Region, 194.454, 537.067, 70.29)

union2 (ROI_0, TMP_Region, ROI_0)

connection (ROI_0, ConnectedRegions)

*产生一个矩形ROI_1

gen_rectangle1 (ROI_1, 216.115, 27.793, 424.854, 674.179)

*把这两个region做差集（ROI_1在第一个参数）

intersection (ROI_1, ConnectedRegions, RegionIntersection1)

*把这两个region做差集（ROI_1在第二个参数）

intersection (ConnectedRegions, ROI_1, RegionIntersection)
