区域封闭填充

大佬们，绿色区域应该用什么封闭（红色线条）填充

1. shape_trans (ROI_0, RegionTrans, 'convex')

风景你好 发表于 2025-1-15 18:45

这样的话左边的曲线特征丢失了，整体区域变成梯形了，还有其他办法吗

红色线条是我自己手画的，想问一下哪个算子能进行这样的操作

看能不能满足你的需求

大佬，为什么我做的是这样的

谢谢大佬，已经解决了，C#还没怎么学，不太会，哈哈哈

看一下最下面缺口多大，然后使用闭运算矩形结构元素就可以了
closing_rectangle1 (Regions, RegionClosing, 260, 10)
