弱划痕检测

第二张图的划痕在哪里？左下角那块吗

在图像右上方那里，肉眼可以看见

用canny算子试试？

我尽力了，拉普拉斯好像还是会有误检
read_image (Image, 'E:/桌面/200010vas7fdfdddgsi6ya.jpg')
dev_open_window_fit_image (Image, 0, 0, -1, -1, WindowHandle)
rgb1_to_gray (Image, GrayImage)
edges_sub_pix (GrayImage, Edges, 'canny', 2, 20, 40)
select_contours_xld (Edges, SelectedContours, 'contour_length', 500, 1200, -0.5, 0.5)
gen_region_contour_xld (SelectedContours, Region1, 'filled')
shape_trans (Region1, RegionTrans, 'rectangle2')
erosion_rectangle1 (RegionTrans, RegionErosion, 17, 17)
reduce_domain (GrayImage,RegionErosion, ImageReduced)
laplace_of_gauss (ImageReduced, ImageLaplace, 1)
threshold (ImageLaplace, Region, -111, -4)
connection (Region, ConnectedRegions)
dev_display (GrayImage)
dev_display (ConnectedRegions)

傅里叶变换

推荐用AI，趋势所在

halcon差异检测能行吗

直方图增强一下，很容易

可以尝试超分一下

向量机怎样

深度学习呢
