we are still working on the project as described in the following topic.
The workflow is running so far, but it still needs a bit improvement.
We are able to detect the bubbles, get the original shape again (Convex Hull node) and extract the diameter. But we still have the problem, that sometimes 2 or more fragments are forming one bubble. I attached some examples pictures.
My idea to fix the problem with example1 is to recombine the fragments, after the convex hull node. Then the small fragments are gone and i can run the connected compound analysis again. But I had no success in recombining the images, filtered by the GroupBy node. The number of labels for each image is different, that makes it even a bit more complicated.
The example2 would still exist after recombining the pictures. I guess there is no solution to detect these bubbles, so I will exclude them through a minimum roundness value.
It would be great if someone could help me recombining the images separated by the GroupBy node. Maybe there is even a solution for example2.
