how to save segmented image annotation in yolo format ? or segmentation support format

i tested it on image & im getting the mask, now i want to save this mask/annotations in yolo or mask rcnn or any segmentation format.
what should i need to do.
thanks.

The issue does not name a file, test, or specific entry point. Start with the example notebooks and the mask produced by inference, then clarify which annotation format should be supported. Done would be an agreed format with a documented way to save the mask and an example or validation.
