Polygon to rectangle bounding box

Hello,

I looked at your github profile and I realized that you have written several convert for Labelme to COCO. I know that we can generate oriented bounding box using polygon using labelme tool.

Do you know how to convert polygon bounding box to rectangle bounding box (you can find more information here:labelmeai/labelme#542)? Do you have written any script for this type of converter?

Thanking you!

KeyError occurs when loading instances_val2014.json with COCO_Dataset.load_from_path

Hi,

I hope to convert COCO to labelme format.

After install pyclay-annotation_utils via pip,

pip uninstall typing -y
pip install cython
pip install pyclay-annotation_utils 

I wanna load COCO dataset

from annotation_utils.coco.structs import COCO_Dataset

dataset = COCO_Dataset.load_from_path(
    json_path='/dataset/cocodataset/annotations/instances_val2014.json',
    img_dir='/dataset/cocodataset/val2014',
)

then I got this KeyError:

Could you help me to resolve it?

Thx.

How can I change Segmentation Transparency?

When visualizing segmentation, I want to change the transparency level. How can I do that?
