漏箔缺陷检测

缺陷检测类算法不太擅长，有没有铁子对如下极片右侧的漏箔有想法的？可以提供良好的思路吗？感谢感谢

上下滤波，剩下的阈值就可以了

1. read_image (Image163610lc80r1zp3phz4v1o, 'C:/Users/Administrator/Desktop/163610lc80r1zp3phz4v1o.jpg')
   
2. edges_sub_pix (Image163610lc80r1zp3phz4v1o, Edges, 'canny', 2, 20, 40)
   
3. select_contours_xld (Edges, SelectedContours, 'contour_length', 140, 20000, -0.5, 0.5)
   
4. difference_closed_contours_xld (Edges, SelectedContours, ContoursDifference)
   
5. gen_region_contour_xld (ContoursDifference, Region1, 'filled')
   
6. union1 (Region1, RegionUnion)
   
7. closing_circle (RegionUnion, RegionClosing1, 7.5)
   
8. connection (RegionClosing1, ConnectedRegions1)
   
9. select_shape_std (ConnectedRegions1, SelectedRegions1, 'max_area', 70)
   
10. closing_circle (SelectedRegions1, RegionClosing, 33.5)
    
11. dev_display (Image163610lc80r1zp3phz4v1o)
    
12. dev_display (RegionClosing)

感谢感谢；铁子，你这个挺有意思的，就是对图像质量以及检测时间上不太友好
