Hi,

I have an image containing 200-250 objects detected by watershed.

In some cases, the algorithm makes mistakes with over/under-detection.

To fix these, I want to re-run watershed locally, using mouse clicks on just those objects, and paste the edited object properties back into the larger list of regionprops.

Is there a good way to go about this? I would greatly appreciate your suggestions and ideas.

Thanks!

Yes, of course. Thanks for looking! I circled the errors.

Note that these are both about a tenth of the entire image, which has ~200-250 objects. Errors like the one I circled are dispersed across the whole image. I'm trying to write a code with a GUI to click and correct them locally instead of changing the entire watershed.
