一、并集
1、union2(Region1, Region2 : RegionUnion : : ) 对象是region
功能：计算两个区域的并集
read_image(Image,'lena')
draw_circle (3600, Row, Column, Radius)
gen_circle (Circle, Row, Column, Radius)
draw_rectangle1 (3600, Row1, Column1, Row2, Column2)
gen_rectangle1 (Rectangle, Row1, Column1, Row2, Column2)
union2(Circle,Rectangle,eee)
2、union1(Region : RegionUnion : : ) 对象是region
功能：把一个区域（这个区域中有很多小的区域，如connection（）算子操作后的region），重新联合成一个整体。
是connection（）算子的反操作。
draw_circle (3600, Row, Column, Radius)
gen_circle (Circle, Row, Column, Radius)
draw_rectangle1 (3600, Row1, Column1, Row2, Column2)
gen_rectangle1 (Rectangle, Row1, Column1, Row2, Column2)
注意：connection（）操作后的out区域是把每个独立分开（out此时其实是一个数组）可以通过修改显示颜色数
来显示不同颜色，而eee和out1是一个整体，无论它的颜色数量是多少都只能显示一种颜色。
3、union2_closed_contours_xld(Contours1, Contours2 : ContoursUnion : : ) 对象是xld contours
功能：计算封闭轮廓的并集，如果输入的轮廓不是闭合的，算子会自动连接轮廓的首尾，把轮廓并集在进行运算
gen_circle_contour_xld (ContCircle, 200, 200, 100, 0, 4, 'positive', 1)
gen_rectangle1 (Rectangle, 40, 40, 200, 200)

注：最终联合起来的轮廓是用不同颜色来表示的，则说明它们一分开联通（像是用connection算子操作过的效果）

draw_circle (3600, y1, x1, R1)
gen_circle (Circle, y1, x1, R1)
