Changing the threshold used by Create Objects in pixel classification

I have some nice images of kidney tissue, where the endothelial cells in the kidney tubules are labeled with GFP. I am trying to segment the tubule cross-sections using a pixel classifier -> create objects workflow.

Is there a way to threshold the output of the pixel classifier at something other than 0.5 in a binary classifier scenario? I want to leverage the fact that the classifier is less confident in the space between closely touching tubules to achieve better separation.

Thanks in advance for the help.

Not an answer to your question, but have you tried using some of the additional Features that help find edges?

Gradient magnitude is listed for edges, for example.

Playing around with those definitely help! I would still like to be able to change the object threshold, but this is a big help for sure. Thanks!
