How to export an annotation which includes both the bounding box and the polygon for the Mask R-CNN architecture

[ryouchinsa]

After labeling polygons, use "Export COCO JSON file" on the Export menu. Each annotation dictionary includes the "bbox" and "segmentation" of the polygon.

You can train the Mask R-CNN model on Detectron2. https://github.com/facebookresearch/detectron2
