read_image (Image, ImageName + Index$'02')

decompose3 (Image, ImageR, ImageG, ImageB)

* Segment dark regions (everything except the fingers)

threshold (ImageR, Region, 0, 159)

connection (Region, ConnectedRegions)

* Select good parts and clutter regions

select_shape (ConnectedRegions, GoodSmallParts, ['area','width'], 'and', [3500,130], [5000,300])

select_shape (ConnectedRegions, GoodLongParts, ['area','width'], 'and', [6000,350], [10000,550])

select_shape (ConnectedRegions, Clutter, ['width','height','area'], 'or', [900,900,0], [1000,1000,100])

* Regions that are neither good parts nor clutter contain broken fingers

difference (ConnectedRegions, GoodSmallParts, Difference)

difference (Difference, GoodLongParts, Difference)

difference (Difference, Clutter, BrokenParts)

shape_trans (BrokenParts, BrokenPartsTrans, 'rectangle1')

这个例程思路很简单，就是select然后difference

但后面有一个算子没太见过，感觉以后能用上。

* Isolate the break for visualization

erosion_rectangle1 (BrokenParts, RegionErosion, 1, 25)

*腐蚀掉边缘，消除边界干扰，缩小ROI

*其实这个参数设置我现在也没明白，反正就两个，宽和高，随便试总能试出来吧。

看了豆丁的文档明白了，可惜没有账号没下载，懒得费劲了，应用非常简单。

connection (RegionErosion, ConnectedBreaks)

shape_trans (ConnectedBreaks, Breaks, 'outer_circle')

dilation_circle (Breaks, Breaks, 6)



后面不用说，看图就明白了。
