c++ - Morphological Reconstruction in OpenCV -

I have some problems during image processing in OpenCV. I have a text on my image, and the use of the opening operation During this, I do not find the proper output. This issue is similar to the one provided in this article.

What can I see, people suggested to use rebuilding in those cases. My question is whether there is a build-in mechanism in OpenCV or a known library / code that applies it? Thanks for the help.

This answer comes late, but here is the basic algorithm for reconstruction:

< Ol>

Input two images: ImReference and ImMarker with marker, & lt; Imprint Imraic

Intermediate Image: ImRec

Output Image: ImResult

Copy ImMarker to ImRark

ImRissult ImRec copy

ImDilated = Expansion (ImResult)

ImRec = Minim (ImDilated, ImReference)

If ImRec! = ImResult then return to step 5.

This is not the most optimal algorithm, but it only uses basic operation.
