How to Remove a Class Under a Category (Attribute) Annotation and Assigned it to New Category Without Re-Annotation
-
I annotated lets say, 'Car' as a category with polygon. The Car category has two classes of ‘Good’ and ‘Bad’ which is ok. Then later, I mistakenly annotated hundreds of Bicycles under Car category ( Big mistake) instead of creating (and adding) a new attribute called Bicycle to annotate all bicycles in the image.
-
How can I correct the bicycle in the image to a new attribute/category called Bicycle without having to delete all Bicycle annotations and re-annotating the bicycles in VGG annotator? Is this possible? Can you please help? I’m desperate because of the painstaking time and effort required to re-annotate.
I'm ready to send the JSON or COCO annotation file if required.
Thanks
