一、提取刹车盘孔洞轮廓
小技巧总结，使用boundary 函数提取区域边界，在边界范围内提取边缘这样可以减少其他纹理干扰
boundary ->dilation_circle -> reduce_domain -> edges_sub_pix
read_image (Image, 'brake_disk/brake_disk_part_01')
binary_threshold (Image, Region, 'smooth_histo', 'light', UsedThreshold)
connection (Region, Holes)
select_shape (Holes, SmallHoles, 'area', 'and', 5000, 10000)
boundary (SmallHoles, RegionBorder, 'inner_filled')
dilation_circle (RegionBorder, RegionBorderDilation, 3.5)
union1 (RegionBorderDilation, ROI)
reduce_domain (Image, ROI, ImageReduced)
edges_sub_pix (ImageReduced, Edges, 'canny', 0.5, 20, 40)
fit_circle_contour_xld (Edges, 'algebraic', -1, 0, 0, 3, 2, RowCenter, ColumnCenter, Radius, StartPhi, EndPhi, PointOrder)
