*利用面积对白色划痕区域进行选择，大于150的区域认为是划痕
connection (RegionClosing1, ConnectedRegions1)
select_shape (ConnectedRegions1, SelectedRegions1, 'area', 'and', 150, 99999)
closing_circle (SelectedRegions1, RegionClosing2, 20)
union2 (RegionOpening, RegionClosing2, RegionUnion2)
*动态阈值提取灰度值比周围暗的区域
dyn_threshold (ImageReduced, ImageMean, RegionDynThresh, 50, 'dark')
closing_circle (RegionDynThresh, RegionClosing3, 80)
dilation_circle (RegionClosing3, RegionDilation, 15)
*补集为白色划痕区域，交集为裂缝区域
difference (RegionUnion2, RegionDilation, RegionDifference)
intersection (RegionUnion2, RegionClosing3, RegionIntersection)
dev_display (Image)
dev_set_color ('red')
dev_display (RegionDifference)
dev_set_color ('green')
dev_display (RegionIntersection)
