Labeling using an open source annotation tool Labelme, export to the COCO format, and convert to the YOLO segmentation format using the JSON2YOLO script.

RectLabel is an offline image annotation tool for object detection and segmentation.
Although this is not an open source program, with RectLabel you can read/write/export the YOLO segmentation format.

@ryouchinsa thank you for reaching out! Labelme and RectLabel are popular choices for image annotation. It's good to hear that you found a tool that works for you. Both tools enable users to export annotations to the COCO format, which can then be converted to the YOLO segmentation format using the appropriate script. Best of luck with your segmentation project! 🖼️

We updated our general_json2yolo.py script so that the RLE mask with holes can be converted to the YOLO segmentation format correctly.

@ryouchinsa that's excellent news! It sounds like you're making great progress. Having updated scripts that handle RLE masks with holes can significantly improve the workflow for segmentation tasks. The community often benefits from such contributions, so thanks for taking the time to refine the tools available for YOLOv8. Keep up the good work, and don't hesitate to reach out if you have any further questions or insights to share. Your efforts help drive the field forward! 🚀
