OpenCV中的形态重建 [英] Morphological Reconstruction in OpenCV

问题描述

在OpenCV中进行图像处理时遇到一些问题.我的图像上有文字，并且在使用打开操作时，没有得到正确的输出.该问题与本文提供的问题非常相似: http ://www.cpe.eng.cmu.ac.th/wp-content/uploads/CPE752_06part2.pdf .

I'm having some problems during image processing in OpenCV. I have text on my image, and during using opening operation, I'm getting not proper output. The issue is quite similar to that provided in this article: http://www.cpe.eng.cmu.ac.th/wp-content/uploads/CPE752_06part2.pdf.

我看到的是，人们建议在这种情况下使用重建手术.我的问题是OpenCV中是否有任何内置机制或实现此目的的某些已知库/代码?谢谢您的帮助.

What I can see, people suggest to use reconstruction operations in that cases. My question is if there is any build-in mechanism in OpenCV or some known library/code that implement this? Thank you for help.

推荐答案

这个答案迟到了，但这是欠重构的基本算法:

This answer arrives late, but here is the basic algorithm for under-reconstruction:

1. 输入是两幅图像:ImReference和ImMarker，标记为< =参考
2. 中间图像:ImRec
3. 输出图像:ImResult
4. 将ImMarker复制到ImRec
5. 将ImRec复制到ImResult
6. ImDilated = Dilation(ImResult)
7. ImRec =最小值(ImDilated，ImReference)
8. 如果ImRec！= ImResult，则返回到步骤5.

这不是最佳算法，但仅使用基本操作.

It's not the most optimal algorithm, but it uses only basic operations.
