halconremove_obj在区域集中移除某个区域

在HDevelop中

read_image (Image, 'D:/bb/tu/4.jpg')
rgb1_to_gray(Image,Image1)
threshold (Image1, Region,[80,87,206,195] , [90,100, 228,205])

remove_obj (Region, ObjectsReduced, 4)
*在区域集中移除某个区域
*参数1：区域集
*参数2：输出区域
*参数3：要移除的区域索引  【区域索引从1开始】

get_image_size (Image1, Width, Height)
dev_open_window(10,10,Width, Height,'black',WindowHandle)
dev_display(Region)

dev_open_window(10,100,Width, Height,'black',WindowHandle1)
dev_display(ObjectsReduced)

在QtCreator中
