bely66 commented 1 year ago

Hi Everyone, It seems you're using a special mask shape, however I want to get polygons from the masks. is there any code to help with that?

Jyouhou commented 1 year ago

what mask shapes are you referring to? Can you be more specific?

bely66 commented 1 year ago

I'm trying to convert the labels of the word level annotations from masks to polygons (4 point polygon), all the annotations are masks
