还是脏污图片的检测

附件的图片，谁能把脏污都检测出来？ 求高人指点

1. read_image (Image3, 'C:/Code/Halcon/赃物检测/3.jpg')
   
2. decompose3(Image3, Image1, Image2, Image31)
   
3. read_image (Image7, 'C:/Code/Halcon/赃物检测/7.jpg')
   
4. decompose3(Image7, Image11, Image21, Image32)
   
5. sub_image(Image21, Image2, ImageSub, 1, 128)
   
6. scale_image_max(ImageSub, ImageScaleMax)
   
7. threshold (ImageScaleMax, Regions, 0, 68)
   
8. dilation_circle(Regions, RegionDilation, 3.5)
   
9. connection(RegionDilation, ConnectedRegions)
   
10. select_shape_std(ConnectedRegions, SelectedRegions, 'max_area', 70)
    
11. dilation_circle(SelectedRegions, RegionDilation1, 3.5)
    
12. shape_trans(RegionDilation1, RegionTrans, 'convex')
    
13. dev_set_draw('margin')
    
14. dev_close_window()
    
15. dev_open_window_fit_image(Image7, 0, 0, -1, -1, WindowHandle)
    
16. dev_display(Image7)
    
17. dev_display(RegionTrans)
