思路很不错呀，如果能自动获取拉伸时的Max值就更通用了
感谢感谢

*狗尾续貂一下，貌似这样通用一些，再次感谢大佬
read_image (Image, 'C:/Users/Administrator/Desktop/221949kdgggg0dxgjhsj0d.png')
decompose3 (Image, ImageR, ImageG, ImageB)
gray_histo (ImageG, ImageG, AbsoluteHisto, RelativeHisto)
Mask := AbsoluteHisto [>=] 100
Selected := select_mask([0:|Mask|-1], Mask)
MinGray := min(Selected)
MaxGray := max(Selected)
scale_image_range (ImageG, ImageScaled, MinGray, MaxGray)
threshold (ImageScaled, Point, 250, 255)
dilation_circle (Point, RegionDilation, 30)
connection (RegionDilation, ConnectedRegions)
select_shape (ConnectedRegions, SelectedRegions, 'area', 'and', 10000, 99999)
intersection (Point, SelectedRegions, RegionIntersection)

没用频域, 转频域性能差一点
当前是使用平均灰度填涂间隔区域，再进行灰度形态学操作后筛选
大佬空了可以 ...

大佬求源码学习一下
