Watershed using c# or c++

Question

I am trying to convert the Matlab function watershed into C# or C++.

I tried to use this code but CvFindContours returns NULL with this image.

I also tried to use this implementation but I had issues with FilterGrayToGray.

Does anyone knows how I can solve my problems or how I can calculate watershed on my image? Can someone explain me more precisely meyers flood algorithm for watershed?

Answer 1

Have you looked at the watershed algorithm provided by OpenCV? Also, here is an example of how to use watershed with OpenCV. Hope that is helpful to you!

Answer 2

Although I think the solution given (OpenCV like) is good, you could also search for a different implementation of watershed. Search for Luc Vincent and Pierre Soille "Watersheds in Digital spaces: an efficient algorithm based on immersion simulations".
