Automatic border between adjacent labels

Dear Hasty team,

I have been testing out for semantic segmentation for the last few days and it’s a very easy to use tool with great functionality and user experience.

However, when I want to create a label adjacent to an already existing one, I often don’t manage to get a clean border between them. Is there any feature to create the borders automatically? I have gone through the documentation but could not find a solution

I would really appreciate it if you can help with this answer.


Hi Tatiana,

when you create masks, use the brush tool (just press “B”) and disable the overpainting mode (top part of your screen). With the overpainting mode deactivated, you will only be able to paint free pixels, allowing you to create an annotation with 100% correct border.

Unfortunately, it is not possible for the polygon-tool yet, but we’re working on it. So stay tuned :grimacing:
