However, I do sometimes spend hours a day just correcting annotations like this, and I think this one change would make one of the most tedious aspects of it twice as efficient for me, if not more. I know technically I could just use the paintbrush tool with “preserve labels” unchecked, but then I have to be much more careful in situations where there are lot of correctly labeled regions adjacent to the one I’m trying to fix.ĭoes this feature already exist in napari, and maybe I am just unaware of it? And if not, is it possible that I could add such a function in my own scripts? I might be able to figure out how to do it if someone can give me a hint of where to start.Īs I’m writing this out, I realize this probably sounds super specific and now I feel a bit silly for asking about it. I imagine it’d basically be like using the eraser tool except instead of replacing the erased label with the background value of 0, it replaces it with the desired label instead. However, I often find myself wishing for some kind of hybrid eraser/paintbrush tool so that I could erase the incorrect label and replace it with the correct one in one go, rather than needing to erase first and then go back over the same place with the paintbrush. Since my cells are quite densely packed, I really like the “preserve labels” feature that allows me to paint/erase one label without cutting into any of the others. manually proofreading and merging results of a watershed segmentation in 3D.
