How about implement SAM? Using bbox or key point to automatically segment objects.

Please check out LabelAnything - A fork of labelme with Segment Anything and YOLO models for auto labeling.

Training loop instructions will be added soon.

I'm working on the integration of SAM with Labelme in here: #1262.
It is still an alpha version, but that would be great if you can try and give feedback. (the PR has installation/usage guides)
