Here are a few sample use-cases of Class Groups:
Visualization — when you visualize each label, things can get cluttered if there are too many annotations. In such a case, you can toggle annotations by each class or by groups. Each group is essentially a "layer" of visualization that you can turn on and off.
Bitmap Mask — when you export your labels, we also create bitmap masks generated from polygon segmentation labels. When we do this, the export action will create a bitmap segmentation mask image for each class group.
When you are done, click "Finish" to complete creating the project. Click on the arrow at the top-left the return to the previous step.
