新人求助，结构光问题

类似于图片中这种结构光打出来的缺陷要怎么提取出来呢，图片是网图有点模糊，求大佬指点下方法

1. read_image (Image, 'C:/Users/47863/Desktop/图片/170307re9ozh9lbcc4cgtj.jpg')
   
2. rgb1_to_gray (Image, GrayImage)
   
3. rgb1_to_gray (Image, GrayImage1)
   
4. mean_image (GrayImage, ImageMean, 15, 15)
   
5. dyn_threshold (GrayImage, ImageMean, RegionDynThresh, 25, 'dark')
   
6. dyn_threshold (GrayImage, ImageMean, RegionDynThresh1, 15, 'light')
   
7. union2 (RegionDynThresh, RegionDynThresh1, RegionUnion)
   
8. dilation_circle (RegionUnion, RegionDilation, 2)
   
9. erosion_circle (RegionDilation, RegionErosion, 2)
   
10. *求补集*
    
11. complement (RegionErosion, GrayImage)
    
12. dilation_circle (GrayImage, RegionDilation1, 1.5)
    
13. connection (RegionDilation1, ConnectedRegions)
    
14. select_shape (ConnectedRegions, SelectedRegions, 'area', 'and', 1500, 2500)
    
15. *做差集*
    
16. reduce_domain (GrayImage1, SelectedRegions, ImageReduced)
    
17. dev_close_window ()
    
18. dev_open_window (0, 0, 512, 512, 'black', WindowHandle)
    
19. dev_display (ImageReduced)
