使用opencv如何去除标记划痕

各位大佬，请问一下这个图片该怎么使用opencv去标记划痕
下面是halcon的代码

1. read_image (Image, 'C:/个人文件/机器视觉/第十课/IMG_1052.JPG')
   
2. get_image_size (Image, Width, Height)
   
3. dev_open_window (0, 0, Width/4, Height/4, 'black', WindowHandle)
   
4. dev_display (Image)
   
5. dev_set_line_width (4)
   
6. threshold (Image, Region, 128, 255)
   
7. reduce_domain (Image, Region, ImageReduced)
   
8. gen_gauss_filter (ImageGauss, 30, 30, 0, 'none', 'rft', Width, Height)
   
9. gen_gauss_filter (ImageGauss1, 3, 3, 0, 'none', 'rft', Width, Height)
   
10. * sub_image (ImageGauss, ImageGauss1, ImageSub, 1, 0)
    
11. rgb1_to_gray (ImageReduced, GrayImage)
    
12. rft_generic (GrayImage, ImageFFT, 'to_freq', 'none', 'complex', Width)
    
13. convol_fft (ImageFFT, ImageSub, ImageConvol)
    
14. rft_generic (ImageConvol, ImageFFT1, 'from_freq', 'n', 'real', Width)
    
15. scale_image_range (ImageFFT1, ImageScaled, 0, 255)
    
16. threshold (ImageScaled, Region1, 0, 1)
    
17. erosion_circle (Region1, RegionErosion, 11)
    
18. connection (RegionErosion, ConnectedRegions)
    
19. select_shape (ConnectedRegions, SelectedRegions, 'area', 'and', 800, 9000)
    
20. dev_display (Image)
    
21. dev_display (SelectedRegions)
